The video contains only a scratch of the details I’m about to explain in this blog.\n潜艇4.0 背景/RC Submarine 4.0 – background (1/10) # 博主做了3个潜水艇。深度不稳定是前几个潜水艇的命门。This project began from a simple question: how to keep a submarine depth at a constant level? Unsteady depth had been a nuisance with the three submarines I made earlier, especially subs 1 and 3. Those submarines were always either at the bottom or at the surface. A good challenge to overcome.\nPID控制可能可以解决这个问题。用树莓派Zero2作为船载电脑，根据压力传感器输入参数调整深度。I thought PID control might resolve the problem. I had some previous experience using PID with a Reaction Wheel Inverted Pendulum, so I knew the basics and had some parts already available, e.g. Raspberry Pi Zero 2. I could buy a pressure sensor and use that as an input for the controller. The whole idea that you could measure depth with a pressure sensor felt very intriguing.\n这次还想尝试用透明亚克力管子来做外壳，这样在水下游起来比较快。自己做盖子，这样的好处是可以用比较薄的材料。磁力传输系统就可以传输比较大的力矩。之前的潜艇用的磷酸铁锂电池来实现遥控，这一代抛弃，实现只有一块电池在潜水艇上。配重方面：之前咏是钢板或者是铅珠，这次使用钨珠，应该可以有效节省空间。There were other things I wanted to try. For the hull I would try a see-though acrylic plastic cylinder, which would be narrower than the previous hulls and therefore faster underwater. I would make the end caps myself, which would enable me to use very thin material, good for magnetic couplings to transfer a lot of torque. The previous subs had a separate Li-Po battery for radio control, which I wanted to get rid off and use only one battery onboard. Extra weight had been steel plates or lead pellets in previous subs, but now I wanted to try tungsten pellets to save space for other stuff. So, a lot of new things, that’s the way I like it.\n如何保持深度 How to maintain depth? # I struggled with this question with my first submarine. What physical principle makes the submarine go to depth X? Then I realized, it doesn’t go to depth X automatically. You need to drive it there, the same way a car needs to be driven to position X by pressing the gas pedal and the brake pedal. The forces in a submarine are buoyancy and gravity. The depth is the result of these forces over time, following Newton’s second law. In mathematics, this would be a double integral: force / acceleration -\u0026gt; velocity -\u0026gt; position.\n悬浮在水中需要浮力=重力。Buoyancy is an upward force caused by the surrounding liquid. It equals the weight of the liquid being displaced. If the submarine volume is 2400 ml, then the displacement is also 2400 ml. 2400 ml of water weighs about 2400 grams. To keep the submarine in neutral buoyancy, not moving up or down, the gravity should be equal to the buoyant force. In this example, the mass of the submarine, including the hull, motors, propellers, tungsten pellets and everything else, should be 2400 grams.\n此处注意浮力不取决于深度。Note that the buoyant force does not depend on depth. If your submarine is 5 grams negatively buoyant, meaning it has slightly more mass than is being displaced, it will sink at the same downward force from surface to bottom. That assumes the submarine stays unaffected during the dive. If the submarine leaks, it’s mass will increase, which will make it sink faster. Or if the hull compresses under water pressure, it’s volume of displacement will decrease, which will again make it sink faster.\n注意压力 Respect the force of pressure # When you as a human dive in a swimming pool, you don’t feel the pressure. That’s why it is surprising how large it is. I had first hand experience of it with my Submarine 2.0 that had a soft plastic lid. I calculated that in 1.5 meters of depth, a normal swimming pool depth, the water pressure will press the lid with 35 kg force. That is like a frigging small human standing on it. No wonder it bent heavily. It resulted in a loss of buoyancy, which I measured to be 66 grams. That was enough to prevent the submarine from rising from the bottom, as the propellers didn’t have enough thrust force. The problem was finally fixed when I added red Lego beams under the lid to support it from bending.\n图中盖子下方的红色横条是用来对抗水中压力的\n如何控制深度 How to control depth # 博主用了三种方法来控制深度。2.0版本中采用的桨叶的方式来控制潜水艇的上下。重力永远等于浮力，靠桨叶的输出来驱动潜艇。按照我的经验，这是最简单的一种方式。对于遥控你有最直接的响应。唯一的问题就是称重得非常精确，不然潜艇就会一直飘上飘下。 I’ve tried three methods for controlling the depth of a submarine. Submarine 2.0 had propellers pushing water up or down. In this method the submarine is weighed to be neutrally buoyant. Gravity and buoyancy stay always the same while the propellers exert force. In my experience this is the easiest to control. You get fast response to radio control buttons. You see the submarine immediately start moving up or down, and when you stop pressing the buttons, it will quickly slow to to a halt due to water resistance. Maybe the only problem I see is that the weighing has to be very accurate, otherwise the sub is always sliding up or down.\n黄色气球通过蓝色管子充气膨胀。The yellow balloon is inflated through the blue hose that connects to a compressor inside the hull.\n3.0版本的潜艇中搭载了一个空气压缩机和一个气球。空气到气球里面时，排水量增加，浮力增加。重力始终保持不变，改变浮力大小。根据我的经验，这是最难控制的。气球膨胀需要时间，特别是乐高的压缩机，效率不怎么高。而且由于压力的变化，气球气体体积带来的变化很不稳定。 Submarine 3.0 was equipped with an air compressor and a balloon. When the balloon is filled with compressed air, it will expand and displace more water, and thus increase buoyancy force. In this method, gravity stays always the same. In my experience this is the most difficult to control. It takes time to inflate the balloon, at least when using inefficient Lego compressors, and therefore the response time from radio control buttons to actual movement is long. Moreover, you’re always at a loss where the neutral buoyancy point is. You need to guess from the sub movement whether to inflate or deflate the balloon. Even worse, as the balloon air compresses under pressure, you’ll lose buoyancy as it goes deeper. 60 ml balloon will shrink to 52 ml at 1.5 m depth, so you’ve gone from neutrally buoyant to 8 grams negatively buoyant while diving to the swimming pool floor. This will make the depth position inherently unstable.\n1.0版本中有一个活塞可以吸水进来，一个电机控制注射器，注射或吸收水到外界。这个方法中吸收水相当于增加了一部分重力。浮力一直保持一致。这个方法和上一个方法的缺点一样，响应的时间比较长，而且平衡的浮力位置比较难找到。 Submarine 1.0 had a piston ballast to suck water in. Here a motor moves a syringe, which has a hose connected to outside the hull, through which water will move into the syringe chamber. In this method the sucked-in water acts as an extra weight that will increase gravity. Buoyancy stays always the same. This has a lot of the same problems as the balloon method, having a poor response time to buttons and difficulty to know neutral buoyancy position for the syringe. In one respect this is better, as the syringe will not compress under pressure like the air balloon does, leading to better stability.\nSubmarine 1.0 has a syringe to suck water in. I’ll try to use syringe ballast for Submarine 4.0. 这次我沿用1.0版本的浮潜方法，一个原因，你可以测量活塞的位置用乐高EV3电机，这个乐高EV3点击有一个转速计tachometer。这就可以帮忙控制循环。这三个方法里最好的应该是2.0版本的，直接浮力=重力，用桨驱动。但是这样是没法设计的很流线型的。（而且我感觉比较费电）。 Why? For one reason, you can measure the piston position with an Lego EV3 motor that contains a tachometer. That will help the control loop. With an air balloon you would have to measure the deflation time, which would be less accurate. The best method out of the three would probably be propellers as in Submarine 2.0, but the hull shape would need to be less streamlined.\nOk, let’s start building.\n潜艇4.0-注射器压舱/RC Submarine 4.0 – syringe ballast (2/10) # 用1.0版本的注射器。到5米都没有问题。所以它能够保持0.5bar不变形。 The first thing to build is a piston ballast. I’ll use the same syringe I did in Submarine 1.0, since it worked very well. It didn’t even leak 5 meters under water, so it should handle at least 0.5 bar of pressure.\nThe syringe # 我觉得普通的60ml注射器就行。 The syringe is a food syringe or marinade injector created by Eotia. It cost 4 euros in a Finnish hardware store, link: https://www.puuilo.fi/marinadiruisku-60-ml\nThe capacity is 60 ml. That should be enough based on my experiences with the first submarine. The hull volume will be roughly 2000 ml, so the syringe will have about 3% control range. Of course you would like to have more capacity to provide safety in case the hull leaks or compresses. Also, fine-tuning the extra weights to neutral buoyancy would be easier. But larger syringe also takes more space inside the hull, so it is a compromise.\n实际上，1.0版本中只用到了60 ml中的25 ml。因为用的乐高的线性传动器（id:61927c01)。动力比较弱，长度比较小。只能维持0.3 bar。 Actually, Submarine 1.0 used only 25 ml of the available 60 ml capacity. That was because it was driven by a Lego linear actuator, part id 61927c01, which has a short range. The linear actuator is also weak, as it couldn’t empty the syringe in 5 meters under water. Max pressure for control was about 0.3 bar.\nSyringe ballast from Submarine 1.0.\nThis time I want to try a different build, to get more range.\n开始搭建🏠/Build # Gear Rack 1x4, 3743\nI put gear racks, Lego part id 3743, alongside the syringe rod. A little grey part to the end to help hold the rack lines in place.\nThe biggest problem was to push gears hard enough against the racks so they won’t skip. I put two 8-tooth gears (10928) to push the rod from both sides, therefore supporting each other. They would also help to hold the gear racks in place. Luckily all dimensions were good so all parts fit very tightly.\nThen I used one of the syringe handles to hold the gears in place lengthwise, to the direction of the rod. This required a lot of trial-and-error until I found a Lego part combination that wouldn’t break.\nLastly, I needed to gear down to provide enough torque. Lego gearbox, part id 6588, has a 24:1 gear reduction. It needs a worm gear (4716) and a 24-tooth gear (3648) to work. Besides increasing torque 24-fold, minus friction, it is very compact, perfect for a submarine.\nThe Lego motor I selected was EV3 Medium motor, because it has a tachometer inside that I can use to keep track of the syringe position.\nI tested the construct for max pressure using a Lego manometer (64065). At first Lego parts slipped out of the handle when pressure increased to 0.3 bar. I put a Deltaco Velcro Strap around to pull the syringe and Lego parts together. That increased the max pressure to 0.5 bar. Beyond that I didn’t try, as parts started to bend dangerously, as you see from the image below. I did multiple tests to verify that it should work under 0.5 bar, which equals 5 meters of depth. But to be safe, I decided to limit the submarine depth to 4 meters.\n注射器的速度是2.7 ml/sec。这个速度不是很快，但是对于PID控制来说足够了，16秒可以从3 ml到45 ml。The syringe speed is 2.7 ml/sec. Not very fast. Moving from min to max position (3 to 45 ml) takes 16 seconds. This will make the submarine react slowly to depth control changes. But as it turns out, it is enough for PID control.\nSo, the construct provides enough force. Actually too much. I had to be careful not to let the syringe run to the end, because it would probably break teeth from the gears. That was a problem. I briefly tried to replace 24-tooth gears with Lego clutches (60c01) that are designed to limit torque, but then the max pressure dropped to 0.17 bar. No good.\nHow to save the gears from destroying themselves? I resorted to tachometer data. I’ll read tachometer pulses and put limits to code on how the syringe is controlled. That was a source of annoyance further down the road, as Raspberry would not always catch tachometer pulses. Therefore I had to routinely check the syringe position data and tune it.\nWirings # Lego EV3 Medium motor is connected to Raspberry using a Lego EV3 cable. I cut one EV3 cable and crimped female DuPond connectors to the end.\nLego EV3 cable with DuPond connectors attached to the end.\nThe cable has 6 wires. M1 and M2 are for driving the motor. TACHO A and TACHO B for reading the tachometer pulses. GND and VCC are used to power the tachometers.\nYou should supply VCC with 5V according to the specs, but that is not an option, as the tacho pulses would have too high voltage for Raspberry to read them directly. Therefore I’ll supply VCC with 3.3V. I’ve used that setup previously with my Reaction Wheel Inverted Pendulum, and it works. I also have checked that the current draw from VCC is 6.5 mA, which is small enough for Raspberry.\n代码/Code # Then I wrote a Python code to read the tachometers. There are two tachometer signals and you know the direction of rotation based on which signal goes to 1 first. The code looks more complex than it should be, but that is because it provides the most reliability. E.g. you can’t read tachoA.value in the signal handler, because by the time that code is executed, the value has already changed. I tested multiple implementations with my Inverted Pendulum. As a side note, you could improve reliability by doing sleeps in the main control loop in small increments. I guess the rising/falling edge detection needs the CPU to be idle or something.\ntachoPower = DigitalOutputDevice(20) tachoA = DigitalInputDevice(16) tachoB = DigitalInputDevice(19) tachoAValue = tachoA.value tachoBValue = tachoB.value def tachoA_rising(): global tachoCount global tachoAValue global tachoBValue tachoAValue = 1 if tachoBValue == 0: #A in rising edge and B in low value # =\u0026gt; direction is clockwise (shaft end perspective) tachoCount += 1 else: tachoCount -= 1 def tachoA_falling(): global tachoAValue tachoAValue = 0 def tachoB_rising(): global tachoCount global tachoAValue global tachoBValue tachoBValue = 1 if tachoAValue == 0: tachoCount -= 1 else: tachoCount += 1 def tachoB_falling(): global tachoBValue tachoBValue = 0 tachoA.when_activated = tachoA_rising tachoA.when_deactivated = tachoA_falling tachoB.when_activated = tachoB_rising tachoB.when_deactivated = tachoB_falling tachoPower.value = 1 Syringe position is calculated from the tacho count. I included hysteresis calculation into the code to compensate for gear backlash and such things.\nSyringe range was set to be between 3 ml and 45 ml. Minimum was 3 to provide some safety from hitting the end, and max was 45 because the hull doesn’t have more room.\nSYRINGE_POS_MIN = 3 #syringe ballast min pos [ml] SYRINGE_POS_MAX = 45 #syringe ballast max pos [ml] SYRINGE_TACHO_COUNT = 19000 #tacho count from syringe min to max pos SYRINGE_HYSTERESIS = 360 #motor+gearbox+syringe backlash/hysteresis [tacho counts] #calculate syringe position if tachoCount \u0026gt; trueTachoCount: trueTachoCount = tachoCount elif tachoCount \u0026lt; trueTachoCount - SYRINGE_HYSTERESIS: trueTachoCount = tachoCount + SYRINGE_HYSTERESIS syringePos = SYRINGE_POS_MIN + SYRINGE_POS_MAX * \\ trueTachoCount / SYRINGE_TACHO_COUNT #[ml] I need to store the syringe position in flash, so that it is not lost during shutdown.\nimport configparser #read config file configFile = open(\u0026#34;submarine_4.ini\u0026#34;, \u0026#34;r+\u0026#34;) config = configparser.ConfigParser() config.read_file(configFile) tachoCount = int(config[\u0026#39;default\u0026#39;][\u0026#39;tachoCount\u0026#39;]) storedTachoCount = tachoCount def writeConfigFile(): global configFile global config global tachoCount global storedTachoCount if tachoCount != storedTachoCount: storedTachoCount = tachoCount config[\u0026#39;default\u0026#39;] = {} config[\u0026#39;default\u0026#39;][\u0026#39;tachoCount\u0026#39;] = str(tachoCount) configFile.seek(0) config.write(configFile) configFile.truncate() Here are the syringe motor output pins.\n#prepare motor drivers motorDive = DigitalOutputDevice(13) motorSurface = DigitalOutputDevice(12) Here is code for driving the motor. syringeMotorCtrl is the PID output. If syringe position is out of limits, the motor is not driven.\n#syringe range limitations if syringePos \u0026lt;= SYRINGE_POS_MIN and syringeMotorCtrl \u0026lt; 0: syringeMotorCtrl = 0 if syringePos \u0026gt;= SYRINGE_POS_MAX and syringeMotorCtrl \u0026gt; 0: syringeMotorCtrl = 0 #drive syringe motor motorDive.value = (syringeMotorCtrl \u0026gt; 0) motorSurface.value = (syringeMotorCtrl \u0026lt; 0) I also added a deadband limit to reduce motor wear, as the PID output is noisy. More of that when testing PID.\nTests # Here is the syringe position data from a typical swimming pool test run. The submarine dives to the bottom, drives around, and comes back up. PID control is in use.\nAs you see, the active range for operation is about 25 ml. That is about half of the syringe size. Therefore the syringe is large enough for control.\nIn the 10+ hours of testing the submarine, the syringe worked physically well. I never noticed any leaks. Then again, it was tested only at a max depth of 1.5 meter.\nTwo times the range limitation failed and the syringe ran against the end. The first time the tacho count was wrong after a long test run. The second time I had made a change to the code that crashed it, leaving the syringe motor on. No teeth was broken in either case, but the gears slipped out of the gear rack and I had to install them again. The fact that Raspberry failed to catch tacho pulses and the actual syringe position would be lost in time, is the biggest complaint I can see with the syringe. It was annoying to need to check the position data and tune it between test runs.\nThe finished syringe unit.\n潜艇4.0-外壳/RC Submarine 4.0 – hull (3/10) # 前几个版本的潜艇，我用了宜家的密封食盒和一个储水罐作为外壳。两个都不错，特别是宜家的密封食盒，盖子很牢靠，很易用。但是这次我想尝试点不一样的。In previous submarines I used IKEA glass food containers and a plastic lemonade pitcher as hulls. Both worked ok, especially the IKEA snap-on lids were easy to use. But this time I wanted to try something different.\n设计Design # 外壳要比较坚固牢靠。不会因为压力太大就散架了，或者被压扁了，否则就会损失压力。像2.0版本的软盖子就不行。The hull has to be rigid. It cannot bend or compress under pressure, otherwise I’ll lose buoyancy, like with the Submarine 2.0 soft lids.\n外壳需要是透明的。It needs to be transparent. I couldn’t even imagine building the thing, solving problems and checking everything is ok before dive if I couldn’t see inside.\n尽量是流线型的。尽可能窄，这样前进的速度就会比较快。前端想装个摄像头，所以前端最好是平的。后端也得是平的，才能装上磁力的动力装置。It is good to be streamlined. As narrow as possible to increase movement speed. But also, I want an on-board camera to the front, so the front has to be flat. The back also needs to be flat for the large magnetic couplings I’m going to use. Not optimal for speed, but fast enough in hindsight.\n所以外壳要是两头平的圆柱体。 So, I decided to make a cylinder with flat ends. Plain and simple.\n最小直径是多少？主螺旋桨的磁吸配对需要4厘米。左右螺旋桨需要2.5厘米。外壳的厚度是3mm。本来以为10cm差不多。后来加到11cm。 What is the minimum diameter? Magnetic coupling for the main propeller will take 4 cm, as I intend to base it on a 40-tooth Lego gear, like in previous subs. For left/right turn I first envisioned using a linear magnetic coupling, similar to Submarine 3.0, but in the end I changed it to a 24-tooth magnetic coupling. That will take 2.5 cm. Some clearance is needed between the magnets. For the lid sealing I will use a piece of a smaller cylinder that is attached to the flat lid. The lid sealing takes 2 mm and the hull thickness is 3 mm. With this information I draw a sketch with 10 cm outer diameter. In this drawing everything would fit but with little room for error. Therefore I increased the diameter to 11 cm, just to be on the safe side.\n最小长度是多少？整支注射器得要23cm。连接到注射器的管子也需要一些空间。所以总的25cm What is the minimum length? The syringe takes 23 cm when fully extended. The hose connection to the syringe will take some space also, so a total of 25 cm, a good round number. I was able to find a 25 cm length cylinder. In the end, the hull was a tad too short for the syringe. It extended only 45 ml out of 60 ml, as it would hit the lid supports. Well, good enough.\n亚克力管子外壳/Acrylic plastic cylinder # 我用到的是两种亚克力管子：外径是11cm的和外径是10cm的。长度25cm，厚度是3mm。10cm的是用来做盖子的内衬的。I bought two Perspex acrylic plastic cylinders: 11 cm and 10 cm in outer diameter, length 25 cm for both, thickness 3 mm for both.\n可用的亚克力管子\nSAN材料板/SAN plastic sheet # 苯乙烯丙烯腈。这个材料2mm厚，30x30cm的尺寸。我觉得我们用亚克力也可以。I bought a plastic sheet made of styrene-acrylonitrile, also known as SAN. Thickness 2 mm thick and size 30×30 cm. It cost 5 euros in a finnish hardware store Biltema, link: 亚克力板-可加工\n盖子尽量越薄越好。越薄就意味这越大的扭力。这个刚性还行。 裁切我觉得可以交给工厂。 I wanted the lid thickness to be as small as possible for magnetic couplings. Less gap means more torque. But of course it shouldn’t bend or break. The 2 mm sheet felt rigid enough in my hands when I tried it before buying.\n粘上盖子/Gluing plastics # 测试了四种胶。热熔胶、硅胶、塑料胶、502.I’ll need to glue SAN plastic to acrylic plastic. How do you do that? The bond needs to be watertight and unbreakable.\nI decided to perform a little test with four glues:\nhot glue Biltema silicone (a cheap brand) Bison plastic adhesive Gorilla super glue 这里只展示结论。502最好。502在沾上之后会形成一些蒸汽，如果通风不够，那么很容易形成雾状沉淀在盖子周围。但也可以用抛光颗粒解决这个问题。\n密封/Sealing # 接下来就是密封。刚开始的状态是这样的。外壳和盖子中间有2mm的空隙。The next thing was to seal it watertight. Here is an image of the starting point. Between the lid cylinder and the hull cylinder there is a 2 mm gap.\n用o-ring。买了2m长的2.5mm的NBR橡胶。70束，70束相对来说偏硬，我更喜欢软一点的材料，但是找不到。\nI measured the o-ring length. I read it should be 0-5% shorter than needed, to give it a small stretch. But I had trouble installing that, so I cut it 15% shorter. 2.5 mm is a bit too thick for 2 mm gap, so stretching will make it thinner and easier to install.\n","date":"2022年9月26日","externalUrl":null,"permalink":"/post/%E8%BD%AC-%E8%AF%91%E4%B9%90%E9%AB%98%E9%81%A5%E6%8E%A7%E6%BD%9C%E6%B0%B4%E8%89%87%E4%B9%90%E9%AB%98rov/","section":"Posts","summary":"如果能在池塘、湿地或者开阔水域玩这个将会非常有趣。","title":"[转+译]乐高遥控潜水艇（乐高ROV）","type":"post"},{"content":"","date":"2022年9月26日","externalUrl":null,"permalink":"/tags/academic/","section":"Tags","summary":"","title":"Academic","type":"tags"},{"content":"","date":"2022年9月26日","externalUrl":null,"permalink":"/tags/%E5%BC%80%E6%BA%90/","section":"Tags","summary":"","title":"开源","type":"tags"},{"content":"","date":"2022年8月28日","externalUrl":null,"permalink":"/tags/travel/","section":"Tags","summary":"","title":"Travel","type":"tags"},{"content":" 前奏 #

“咸水湖国家湿地公园⛲️”是个名不副实的镇立免费公园。停车免费，栈道短暂。稍微走走就到了尽头。\n⛰️长白山景区一共分为三个景区：北景区，西景区和南景区。北景区靠近二道白河，是接待游客量最多的景区。长白山的景区商业化非常严重，无法自由规划路线。这对于很多年纪较大或是没有车家庭游客非常友好。小镇上的公交沟通长白山站到长白山北景区之间的路径，途径住宿的地方，交通十分便捷。在这个小镇上，可以步行到达超市，餐馆，银行等各种设施地段。租车反而是一种不明智的选择。在北景区停车还需要花费25元停车费，所以我们决定将车停在酒店楼下，公交前往北景区门口。\n🏔️在山下购买一张门票加游客集散地到北景区的车票。说实话，这车票是真贵，但没办法，旅游局订的。山顶还要再买一张通往山顶的车票，这个车票我没有在小程序端看到过，但是回来后的几天，我在小程序上有看到在售的山顶车票。北景区包括了天池，绿渊潭，长白山瀑布，地下森林等几个景点。其中天池，瀑布和地下森林最值得一去。\n长白山是一座休眠火山，上一次喷发是在大约260年前。当时的中国还是在清朝的统治下。火山休眠后，火山口承接天降水形成天池。据说天池深150米左右，水体里营养盐少，生物少，所以天池的水很蓝，呈现马尔代夫周边海水的蓝色。据说长白山天池很难见到，这里多云雾，且半年时间常有积雪。景区内最好的摄影地点被景区工作人员占据，要拍照需要再额外收钱。\n长白山瀑布是在一个类似优胜美地峡谷的地方。瀑布水来自天池。近来降水偏少，瀑布水量偏小。山间空气清新自然。遗憾的是不能飞无人机航拍。\n雨后的地下森林很漂亮。我们穿着雨衣穿行在“雨林”中，听着雨打树叶混杂着昆虫和鸟儿的声音。\n下山后在二道白河飞了一下DJI FPV无人机。二道白河的夜景还是非常好看的。\n8月26日 # 🌲长白山自然保护区\n驱车前往西景区松江镇。开始感受自驾的乐趣。路过一个蓝莓果园，一人50元采摘蓝莓🫐，很有趣的过程。蓝莓树是灌木，采摘十分容易，但是一簇蓝莓的成熟时间是不同的，通常是最外的一颗蓝莓已经成熟，内部的绝大多数蓝莓还尚是红色；内部的蓝莓成熟了，外部的蓝莓已经烂了。蓝莓的运输也是个非常大的问题。饱满的蓝莓没多久就会变软，挤压很容易导致蓝莓破损，这也就是蓝莓为什么那么贵的原因了。\n路过一个岔道，拐进去越野探险。不过没什么发现。\n路过一个观景台，停车发现一条大蛇在晒太阳。\n路过一个岔路口，是一条被封住的小路。门口的大爷说这条道直通长白山景区的西门。我们游说他给我们放行，他耳根子软就答应了我们。这是一条一车宽的路。我们步行了一段。发现了很多很有意思的植物和昆虫。开车在这条道上走，前后都没有车，畅通无阻的感觉真是不错。偶尔有花栗鼠🐿️，松鼠从道间穿过，也有大鸟从车前上方的天空穿过。整个驾车穿行的过程是十分愉悦的。可惜道路间没有专门的停靠点和景观点。道路太过狭窄，我们担心来车，所以一路上也不敢停留。在中间有个小湖和一栋建筑，是某个机构的办公室。门前有两条小狗。在这里钟老师第一次坐上驾驶员的位置，体验油门和刹车的魅力。\n到了景区西门，果不其然不让进去。不过有了这趟长白山自然保护区内部之旅，我们已经很开心了。而且天空已然乌云密布。我们决定返回松江河镇，在路上我们看到一处松江河国家森林公园，可惜不让进。我们去了一趟大桥边，疑似发现中华秋沙鸭。离太远了，不能确定。\n8月27日 # 核酸马上就要过期，我们打算先去做个核酸。按照经验，我们下飞机、下高铁都有核酸检测点，所以松江河站🚉应该也有核酸检测点。按照这个逻辑，我们先赶往松江河站，但并未发现火车站附近有任何核酸检测点。询问当地火车站工作人员得知，附近路边🈶️一核酸检测点。驱车前往该地。本应8点开始的核酸检测8：20检测人员才赶到。8:40开始第一批核酸检测。快要排到我们的时候被告知我们需要社区流行病学调查后方可检测核酸，或到县医院进行核酸检测。只好作罢，前往抚松县医院。抚松县是著名的长白山人参之乡。这里城市建设比松江河镇美观一些。在下高速之后，我们被拦下来进行核酸检测。正所谓踏破铁鞋无觅处，得来全不费功夫。\n做好核酸之后，我们前往如来寺拍摄了无人机视频。 从抚松返回二道白河，还车加赶赴长春。在长春，我们看了夜场的《新神榜：杨戬》。\n8月28日 #

有微舍公寓的住户反映，他们观察到有大批人员入住微舍公寓。当时微舍公寓的防疫政策是只出不进，不允许住户离开微舍公寓的大楼。微舍公寓大部分住户对于大批人员入住感到不满。\n5月25日23点 # 两位微舍住户在一楼发现拖着行李箱即将入住的人员，上前阻挠其入住。在一楼大厅迅速聚集了大量微舍公寓的住户。微舍公寓负责人报警。\n5月25日晚24点 # 警察来到现场，与住户代表和负责人协商。微舍负责人宣称今晚入住的20余人是上海复工复产白名单企业（他们宣称是京东，实则是京东外包）的员工，这些员工均由外地（杭州）包车迁入，均持有24小时核酸检测证明，他们需要在今后一段时期出入园区投入复工复产，出入时保持闭环管理。微舍住户得知此情况以后要求当晚入住的住户搬出。协商未果。警察要求微舍负责人将当晚入住的住户搬出，微舍负责人一直不愿意配合。\n5月26日晚0点30 # 两名民警赶到，对微舍负责人进行了大声的口头教育，指出其行为并未合规，且未曾向当地派出所报备，责令其尽快将当晚入住的住户叫出。经过大约一个小时，微舍的管家三次进入公寓确认房间和人员。当晚入住的人员携带其行李被叫出并集中在微舍大门门口。\n5月26日凌晨2点 # 两辆中巴车将当然入住的人员60余人全部接走，离开微舍所在园区。\n思考： # 从微舍老板的角度出发，将复工白名单企业和自身产业里的空房间联系起来是再妙不过的选择了。疫情下，每一个上海人都在遭受资金链的压力。能够联系到批量入住的租户，而且有可能他们所付租金比正常的租户还多，这本身就是投入小而获利多的买卖。如果没有派出所需要登记报备这一说，微舍的租客甚至都没有权利要求已经入住的人员当晚撤离。根据微舍老板的描述，他的做法都符合法律和防疫规定。是不是真的符合我们现在已经无从考证了，但是从现场民警的反应和做法，应该已经给予微舍老板口头教育并罚款了。原本我想，如果有可能，就走法律途径起诉。冷静后想想，似乎起诉的点都很弱，不足以对微舍老板造成实质性的打击。\n","date":"2022年5月28日","externalUrl":null,"permalink":"/post/5.25-5.26-%E5%BE%AE%E8%88%8D%E5%B0%8F%E8%8C%83%E5%9B%B4%E5%86%B2%E7%AA%81%E5%B0%8F%E8%AE%B0/","section":"Posts","summary":"在上海因为新冠疫情被封控的两个月时间里（3月28号到5月31号），上海市浦东新区曹路镇川沙路809号微舍共享社区公寓（下面简称微舍）不允许公寓的租户在园区活动甚至下楼。但是5月25日，在临近解封的前夕，却闹出了以下不愉快事件。","title":"5.25-5.26 微舍小范围冲突小记","type":"post"},{"content":"","date":"2022年5月1日","externalUrl":null,"permalink":"/categories/anarctic/","section":"Categories","summary":"","title":"Anarctic","type":"categories"},{"content":"","date":"2022年5月1日","externalUrl":null,"permalink":"/tags/anarctic/","section":"Tags","summary":"","title":"Anarctic","type":"tags"},{"content":"✒️ 作者：\n伍洋，北师大鸟类学在读博士\n张海峰，自然资源部第二海洋研究所助理研究员\n声明 #

上船会配发一个红色行李包🧳，包含了基本的衣物：\n项目 数量和备注 拖鞋🩴 1 房间内穿，不能出房间 老北京布鞋 1 船舱内穿，不能上甲板 登山鞋🥾 1 防寒鞋 1 冰区作业时穿 白色长袖速干衬衫+速干长裤👖 1 深色短袖立领T恤👕 1 蓝色内胆+薄款长裤 1 红色冲锋衣+防水长裤 1 魔术头巾 1 保暖面罩 1 针织帽 1 折叠鸭舌帽 1 墨镜/镜片夹🕶️ 1（建议自备近视太阳镜，可根据紫外线强度变色的最好。如果喜欢墨镜不需要镜片夹，在最开始的队员报名表上选择“没有近视”。如果是近视的朋友，建议多备两个眼镜，以及隐形眼镜、太阳镜等，以应付作业、装逼等不同需求和意外） 唇膏💄 2 防晒霜🧴 1（女队员说不是很好，建议自带） 手套 1 船上热空调可以，不用带太多御寒衣物，作业穿企鹅服搞定，秋裤穿到的机会不多，毛衣等厚衣物用到的机会特别少，平时以衬衣、短袖为主，也可穿队服。\n建议带1-2身健身、跑步等场合所用的具有速干、吸汗功能的内衬，即可做秋衣秋裤贴身穿、还可臭美健身用，裸个奔都不是事儿\n可能是S38限定：安利护手霜、维生素、蛋白粉等\n建议：\n多带几条短袖短裤，船舱内一般都比较热，尤其是热带地区。 多带一些衣架、粘钩。 衣物等按功能准备，除了发的，带好不同类型的，如装逼或者船上活动用的相对正经的衬衣、干脏活累活的时候不心疼的旧衣服。 暖宝宝，酌情带个几片，2月末大洋作业或者风雪天或者收放潜标长时间在户外有奇效，保护腰部、膝盖甚至脚底板 食 🍎 # 🥣规定的就餐时间：\n☀️早饭：7:15-8:00\n🌞午饭：11:15-12:00\n🌛晚饭：17:15-18:00\n✨夜宵：23:00-24:00\n实际开餐时间会提前15分钟，受欢迎的菜品会急剧增加内卷。\n重要节点晚餐都会有类似自助餐形式的加餐（10人桌餐）。\n早饭有牛奶🥛、酸奶、豆奶交替出现，水果🍌、碳酸饮料和果汁🍹午饭和晚饭都会有，但前期会比较抢手排不到，后期会比较充足（此时大多数饮品都接近过期）。\n喜欢喝酒🥃的多带点下酒的方便食品，集体生活酒精消耗量远超平时。\n夜班作业会限量供应袋装方便面🍜、饼干🍪，可适量自带补充体力的食品。\n雪龙号会发一大一小两个304不锈钢碗🥣（也可能是可以微波的类似塑料一样的碗）和1双筷子🥢，碗上只有编号，容易弄混，可以自己带喜欢的碗筷。筷子用半年不能更换，不发勺子🥄，建议自带。\n船上发的饮料杯和水杯质量都很差，建议自带多带，而且不容易弄混。\n船上不限电，可以带小锅、小蒸笼方便自己蒸煮食物\n比较受欢迎的零食： # 瓜子、花生🥜、薯片、海底捞小碗酸辣粉、方便面、螺蛳粉\n麻辣零食、星球杯、口香糖、果脯、肉脯、果冻、棒棒冰\n带点下饭的东西（老干妈），补给之前伙食会比较难吃。\n如果有健身需求，自带蛋白粉等物资。\n船上有免税香烟，开售后早点排队，否则可能难以买到喜欢的品种。\n尤其是自己平时就比较喜爱的东西，尽量带一些，以便过过嘴瘾\n疫情当前，补给难度增加，新鲜蔬菜和水果较缺，会发放一些维生素类的东西，吃完也可以问船医讨，但还是建议自备一些\n船医处有各种常用药物，有特殊需求的可以考虑自备或报名时就提出需求\n饮用水如果有特殊需求，比如泡好茶，或者不喜欢压舱水、净化水，可酌情带一定数量的4L、5L桶装水，日常喝较好\n带些330ml的小瓶装水，便于作业期间随时取用；方便面这种可以带一点，尤其是奇葩口味的\n饮料一般情况下会敞开供应，但可以自己带一些特殊口味的，也是社交硬通货了\n总之一句，想到了就带一点，不一定很多，有一点就好，求人不如自备。\n住 🏠 # 雪龙号一张上下铺，一张沙发，住三个人。上下铺有床帘和壁灯，沙发没有。沙发靠近舷窗，有可能出现漏水现象，注意。沙发的好处是任何时候都可以坐着躺着，但上下铺基本上只能拿来睡觉，坐着头会顶到天花板。\n床上用品：船上配床垫、1条褥子、1条被子、1个枕头；三个月船上会更换一次，可以带一床夏凉被。\n洗漱用品：会有一包基础的洗漱用品，包含牙膏牙刷毛巾和洗发水沐浴露。会不太够用，这些建议多带一套，\n电动牙刷记得带换用刷头。发毛巾1条，半程时又补发1条，需自带浴巾。\n纸巾：船上只发卷纸，可自己携带小包抽纸。\n洗衣机：船上有洗衣房，内设洗衣机和烘干机。航行和作业期间开放时间有限，尤其到冰区作业时，由于海冰容易堵塞进水入口，淡化水制水缓慢，用水紧张，洗衣房常处于关闭状态。常年需要手洗衣物，可自带折叠脸盆，有条件的也可自带简易洗衣机。\n雪龙号是欧标插座，船上陪有转换接头，但有时会找不到，可以找实验室要，或者上船第一天给船上反映，船工将会购买。带些插线板备用\n船上马桶确实易堵塞，比较麻烦，要有心理准备，谨慎丢纸进去\n可备一个有很多夹子的那种衣架，晾晒袜、手套、内衣有奇效\n备点绳子可以在房间或者厕所内找地方拉起来当晾衣绳。\n行 🚶‍♀️ # 岸基作业或者参观科考站需要充电宝，温度低手机很容易就会冻没电。\n一般有两架直升机，用于卸货运人，乘机时一定要听指挥，这个最要紧！\n其次不要手欠，去机库参观时也不要摆弄直升机的尾桨、仪表等关键部位；\n卸货、收标或者去站上玩耍时可能会用到黄河艇、中山驳或橡皮艇，爬绳梯时胆大心细，注意技术动作，手抓住人尽量靠近船体，重心贴近船舱更安全；\n在艇上不要嘚瑟，注意冰山和大浪\n在冰面上作业或玩耍注意冰裂隙和融池\n🎵 娱乐 #

Our study focused on the Yukon River, one of the regularly ice-covered Arctic river basins. Tributaries of Yukon River are commonly categorized into three classes (Figure 1) according to their major contributors: ‘blackwater’, ‘whitewater’, and ‘meltwater’(Striegl et al., 2007). Blackwater tributaries, such as the Porcupine River, exhibit highly-colored river water with high DOC concentration and relatively lower DIC loading because they are draining through permafrost wetlands and peatland. River water in whitewater class are mainly derived from groundwater. High DOC but low DIC loadings are their characteristic features in river water. Finally, the tributaries in meltwater class, such as Tanana River, are dominated by meltwater from glaciers, perennial ice and snowfields. DOC concentration in these river water is relatively low, but the inorganic carbon loadings (including PIC and DIC) are high.\nFigure 1. Watershed of Yukon River. The Yukon River basin covers a large exiguously-populated area of permafrost (generally underlain by continuous permafrost: 16%; generally underlain by discontinuous permafrost: 40%; generally underlain by moderately thick to thin permafrost (15-150 m): 24%; generally underlain by discontinuous permafrost: 6%; generally underlain by numerous isolated masses of permafrost: 5%; and sporadic masses of permafrost: 9%) (Brabets et al., 2000). The inserted figure shows where Yukon River basin locates in the northwest corner of North America. Sampling location, denoted by a blue dot, in the downstream is known as Pilot Station. Water samples collected in the site integrate all characteristics in the whole Yukon River watershed.\nWater samples were monthly collected from upstream and downstream Yukon River between July 2004 and September 2005. Strong seasonality was observed during the one-year monitoring. First flood in 2005 occurred in the middle of April. DOC concentration was consistent with discharge rate. Water from glacier and snowfield composites lower δ18O and δ2H. When temperature raised, large meltwater input negatived δ18O in the river water from average -17.5 ‰ in the winter to average 20.1 ‰.\nFigure 2. Daily discharge (upper left panel), DOC concentration (bottom left panel), δ18O (upper right panel), and δ2H (bottom right panel) of sampling seasons between 2004 and 2005.\nFigure 3. SUVA254 (left) and s275-295 (right) in low-molecular weight phase (upper) and colloidal organic matter (bottom).\nFigure 4. biological index (BIX) and humification index (HIX) in low-molecular weight phase (upper two plots) and colloidal organic matter (bottom two plots).\nThree fluorescence components were decomposed from Excitation-Emission Matrix (EEMs), including two humic-like components and one protein-like component (Figure 5). The ratio between protein-like component and humic-like components indicates the water chemistry conditions in the Yukon River (Figure 6). Relatively high ratio value in the ice-covered season suggested thriving algae community activity under the ice.\nFigure 5. Three components decomposed from EEMs-PARAFAC. Component 1 (left) and Component 2 (middle) are humic-like, and Component 3 (right) are protein-like fluorophore.\nAlmost previous studies about Yukon River concerned about flood season in summer (Guo \u0026amp; Macdonald, 2006; Spencer et al., 2008; Striegl et al., 2007). Few researchers focused on slowly-flowing Yukon river water under ice partly due to extreme sampling conditions in winter (Guo et al., 2012). However, it is still important to know the mechanisms of Yukon River in winter. With respect to the water source, major contributor in winter is ‘whitewater’, which derives from relatively-eutrophic groundwater containing exceeding DIC and DIN (Guo et al., 2012). Additionally, hydrological dynamic under ice is inactive. Here we hypothesis that the stable ice-covered river water ecosystem capacitates stronger bio-activities compared to the highly-disturbed spring and summer.\nIn both low molecular weight phase and high molecular weight phase, biological index (BIX) gradually escalated from warm to cold, while humification index (HIX) were lower in the winter (Figure 4). It implies more intense biological activities in the ice-covered aqua-environment. The concave HIX patterns showed that the dominant terrestrial input in spring and summer, and autochthonous DOM contributed more in the winter. Furthermore, PARAFAC-decomposed components ratio supports this hypothesis as well (Figure 6). The cliff declines of ratio between C3 and sum of C1 and C2 appeared in both colloids and molecules smaller than 1 kDa. The increasing ratio values are probably related to the boost of phytoplankton community.\nFigure 6. Ratio of Component 3 to summary of Component 1 and Component 2 in low-molecular weight phase (left panel) and colloidal organic matter (right panel).\nSupplementary: # Figure 7.

Lesson2 Grouping and Chaining with dplyr # summarize是个很重要的函数。例如\nby_package \u0026lt;- group_by(cran, package) pack_sum \u0026lt;- summarize(by_package, count = n(), unique = n_distinct(ip_id), countries = n_distinct(country), avg_bytes = mean(size)) n()表示的是括号内的字段有多少不为空的数据，n_distinct表示括号内的字段有多少不重复的数据。这个函数是length(unique(x))的简化和快速版，更容易操作。\n如果需要使用递进关系的函数，那么可以使用%\u0026gt;%连接符，可以连接不同函数。例如，\ncran %\u0026gt;% select(ip_id, country, package, size) %\u0026gt;% mutate(size_mb = size / 2^20) %\u0026gt;% filter(size_mb \u0026lt;= 0.5) %\u0026gt;% arrange(desc(size_mb)) 在上面的例子中，select函数需要用到cran数据框架，mutate函数需要用到select函数处理之后的数据框架，……以此类推。而在末尾的%\u0026gt;%连接符正好起到这样的作用。\n","date":"2017年2月20日","externalUrl":null,"permalink":"/post/learning-r-using-swirl/","section":"Posts","summary":"用Swirl学习R语言，Learn R, in R # how to import data (read function) how to manipulate data wit dplyr\nlesson: Getting and Cleaning Data # 我们可以使用read.csv函数来导入数据。具体查看?read.csv，例子\n#set a path to csv file path2csv \u003c-\"E:/R-3.3.2/library/swirl/Courses/Getting_and_Cleaning_Data/Manipulating_Data_with_dplyr/2014-07-08.csv\" #use read.csv to read the csv file mydf\u003c-read.csv(path2csv,stringsAsFactors = FALSE) #stringsAsFactors: logical: should character vectors be converted to factors? 使用dim()查看数据的行列情况\n","title":"Learning R using Swirl","type":"post"},{"content":" R语言学习笔记 # 这里是关于一些R语言的语法备忘 Learning Website\nUnit 1 Assignment and basic calculation # myapples = 3 or\nmyapples \u0026lt;- 3 +, -, *, /, ^\n%% means the remainder.\nUnit 2 Vectors # combine function: c()\nnumeric_vector = c(1,2,3) #Or c(1:3) sum()calculates the sum of all elements of a vector. mean() calculates the average of all elements of a vector.
