船舶横倾的水尺计重(国外英文资料)The ship is heeling with a measure of water?????? Ship is floating in a state, because the cargo loading or water hydraulic load, the relationship between ship tilt, both sides of the draft produce different, this is the roll of the ship. The value of the right and left side is equal to the product of the tangent function tg theta of the ships width and the Angle theta. That is:T1 = BM, tg theta.????? Because the ships wide BBM is determined, it can be calculated by the heeling Angle of the ship. Or in a boat, the heeling value of a ship is rolling.????? We are in real water meter work, because the external draft is not always easy to see. In theory, you can use this formula to calculate the other side of the water ruler based on the inclination of the ships inclinometer and the water ruler in the ship. But actually the accuracy is worse! First observation uncertainty of ship inclinometer is big, can even read the accuracy of 0.1 °, and if the ships BM is 20 meters wide, then calculate the uncertainty of the other side draft is 0.035 meters; An average water ruler is 0.013 meters in uncertainty. This number is not acceptable in the meter weight. But it can be done as a proof of the external measure.????? Over the years, colleagues from all over the world have come up with a research paper based on the slope of the ships tilting, and the use of a high-precision inclinometer (level instrument). There is a connection. All let me deny! The reason is simple: it is not easy to find parallel planes of the relative water ruler.????? For example: where do you measure the high-precision inclinometer? It should be relative to the driving platform. I said, no, I cant jump to conclusions! At your desk, do you say level? Can you see that your desk is still in a horizontal position if you put two dollars on one side of your desk? The naked eye is not easy to see! Lets say the desk is 1.20 meters long. A dollar coin is 0.001 meters thick. This way, if the ships wid
