采用DPIV（Digital Particle Image Velocimetry）测量方法,开展了微重力条件下细水雾速度场特性的实验研究。研究结果表明：微重力条件下,细水雾竖直方向速度明显下降,整体雾场向四周扩散。根据牛顿第二定律,建立细水雾雾滴受力方程,模拟细水雾在常重力和微重力状态下的雾场情况,得出了与实验结果相同的结论。

DPIV（Digital Particle Image Velocimetry）is used to measure the velocity field of water mist in microgravity. Results of research show that in microgravity, the velocity in vertical direction of water mist slows obviously, and the water mist field spreads around. According to the Second Law of Newton, the force equation is built to simulate the velocity field of water mist both in normal and microgravity environment. The same conclusion with what is experienced in experiments is obtained.
