摘　　要：微重力条件下,物体的重力影响几乎消失,这时液体的流动特性会发生不同于重力作用下的变化.为了形象地观察到这个变化过程,根据微重力原理建立了一个短时微重力实验系统.在其模拟的微重力环境下,观测到油滴下降时的形状与速度变化.通过观察该实验,提高了学生的观察能力及总结物理实验规律的能力.The gravity effect almost disappears in a micro-gravity environment. The flow characteristics of liquid will be different from itself under the gravity condition. In order to observe the change of the oil droplets, we have built a short-term micro-gravity experimental system, and observed. The image of the oil droplets changing process of the speed and the shape. It is important for the education of the student＇s observation ability, scientific thinking ability through these physics observation experiments.
