| 摘 要： | 在原有实验的基础上，采用控制液面下降法，将原实验仪器中的表面皿换成测量杯，利用放水阀控制液体流出速度，从而使数字电压表的示数在液膜拉断前后容易观察，另外在测量杯上标出水平线，以便于判断吊环与液面平行，这样测量出的液体表面张力系数更接近实际值。

| Abstract: | On the basis of original experiment,we change surface plate of former laboratory apparatus into the metrical cup.Through controlling the speed of descent llquld,so the reading of digital voltage gauge can be easily observed when the ring drops out of the surface of the liquid. Besides it is hard to make the ring parallel with the surface of liquid,so we mark on the metrical cup every three millimeters with a single line.As a resuh,the liquid surface tension coefficient measured like this is closer to actual value. |
