| 摘 要： | 应用拉脱法测量了食盐和白糖溶液的表面张力系数，发现：盐溶液的表面张力系数随着溶液密度的增大而增大，糖溶液的表面张力系数随着浓度的增大而减小。测量了自来水与纯净水在不同环境温度下的表面张力系数，验证了液体表面张力系数随着温度的升高而降低的物理规律。

| Abstract: | The surface tension coefficient of saline water and sweet water in the same temperature and different densities was measured using the FD-NST-I liquid surface tension coefficient measuring instrument. And the surface tension coefficient of tap -water and purified water in different temperatures was also measured using the same instrument. Results show that the surface tension coefficient is related to temperature and density. |
