| 摘 要： | 把浸润在液体中的物体拉起,它的底边会带起一层液膜。液膜张力对物体具有向下的作用,而且液体表面张力是一个微小的量值。文章根据光杠杆放大原理,测量出弹簧在液体表面张力作用下的微小伸长量,从而求出液体表面张力系数,得出理想的效果。

| Abstract: | Pulling up the object infiltrated in the liquid can bring up a layer of fluid film,whose tensility has the downward role to the object;moreover the liquid surface tension is a small size.Therefore according to the enlarge principle of optical lever,we may measure spring＇s small elongation quantity under liquid surface tension function,and calculate the liquid surface tension coefficient. |
