摘要
从一个新的角度对金属圆环从纯净水液面拉脱时进行受力分析,分析了纯净水与圆环的之间的相互作用力,从理论上得出金属圆环横截面积会对测量结果产生影响。在此基础上,利用自制金属圆环进行了实验验证。
Force analysis is carried out through a new point of view when metal ring is pulled out from pure water.We mainly do the research about the interaction force between the metal ring and pure water.Accordingly,we find that the cross-sectional area of the metal ring would affect the measurement results.We demonstrate these results by doing experiments with a home-made mental ring.
