An improved oscillating drop method was developed to measure the surface tension and viscosity of a liquid without any external forces under microgravity conditions. The combination of a drop levitation system, a laser backlight system, and a line sensor enables the properties to be measured precisely. The surface tension value from 68.9+/-4.3 mN/m to 71.8+/-4.5 mN/m and the viscosity value of 0.92x10(-3) Pa s were obtained at 23.5 degrees C for pure water. These values agreed quite well with the reported value.
开发了一种改进的振荡液滴法，用于在微重力条件下无任何外力的情况下测量液体的表面张力和粘度。液滴悬浮系统、激光背光系统和线传感器的组合使得能够精确测量这些特性。在23.5摄氏度下，纯水的表面张力值为68.9±4.3 mN/m至71.8±4.5 mN/m，粘度值为0.92×10(-3) Pa·s。这些值与报道的值非常吻合。
