摘要
为使理论和技术的简化,直接牵引法测表面张力是最常用的方法之一,在此实验中我们测量物体的重量,并延长测试天平的力臂,以避免通常所用实验装置的缺点。
Due to its theoretical and technical simplicity.the method of direct pull is one of most commonly used methods for the measurement of surface tension. Our method of performing this experiment by weighing a long object and extending the moment arm of the loading pan of a typical lever balance avoids certain drawbacks of the usual setup.
