| 摘 要： | 研制了新型的液体表面张力系数测试仪,测量了不同流速时液体的表面张力系数。随液体流速增加,液体的表面张力系数先减小,后迅速增加,当液体流速达到3.0ml/s时,液体的表面张力趋于稳定,该值与理论值较接近。

| Abstract: | A new liquid surface tension coefficient measuring instrument has been developed in this paper and surface tension coefficient of liquid has been measured. Surface tension coefficient of whichliquid decreases firstly and then increases. When a flowing speed of liquid is up to 3. 0ml /s,surface tension coefficient of liquid reaches a stable value which approaches a theoretical value. |

| Keywords: | surface tension coefficient flowing speed |
