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。
應用拉脫法測量瞭食鹽和白糖溶液的錶麵張力繫數,髮現:鹽溶液的錶麵張力繫數隨著溶液密度的增大而增大,糖溶液的錶麵張力繫數隨著濃度的增大而減小。測量瞭自來水與純淨水在不同環境溫度下的錶麵張力繫數,驗證瞭液體錶麵張力繫數隨著溫度的升高而降低的物理規律。

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.
