1·Due to the thickening of the surface tension, even if the short term is thin, and then will be in the role of surface tension, reduce the width, thickness back to the balance of thickness.

由于表面张力的增厚作用，即使短期被拉薄，随后会在表面张力的作用下，缩小宽度，厚度回到平衡厚度。

2·The theory and method that the surface tension coefficient of liquid is measured by an electronic analytical balance is introduced.

阐述用电子分析天平测量液体表面张力系数的原理和方法。
