Droplet evaporation on a hot surface under super-gravitational fields was experimentally investigated. A test chamber attached to the end of a rotating arm was constructed to produce the quasi-super-gravitational fields. A hot surface, droplet-forming equipment and a video camera for measuring the lifetime of a droplet were installed in a test chamber. Lifetime curves of water, n-decane and benzene were measured under the gravity of G = 1 to 12. As a result, it was found that an ncrease of the gravitational acceleration led to the decrease of lifetime near the Leidenfrost point.

对超引力场下热表面上的液滴蒸发进行了实验研究。建造了一个连接到旋转臂末端的测试室来产生准超引力场。测试室中安装了热表面、液滴形成设备和用于测量液滴寿命的摄像机。在G=1～12的重力下测量了水、正癸烷和苯的寿命曲线。结果发现，重力加速度的增大导致莱顿弗罗斯特点附近的寿命减小。
