| 摘 要： | 用高速摄影技术研究了高压气体膨胀驱动空气-水界面的瑞利-泰勒不稳定性，获得了空气-水界面的不稳定性清晰图像，得到气炮尖顶运动速度及湍流混合层高度增长速度与时间关系曲线。在横式激波管上用高速纹影诊断技术研究了激波作用空气-SF6界面的里克特迈耶-梅什科夫不稳定性，初步获得了实验图像，可清晰显示混合区变化过程。

| Abstract: | High-speed photography is used to study the Rayleigh-Taylor instability of air-water interface driven by high-pressure exploding gas. Clear images illustrating the instability are obtained, along with the air bubble peak speed and turbulent mixing speed. The RM （Richtmyer-Meshkov） instability of air/SF6 interface driven by shock wave is also researched by using high-speed schlieren technique on the horizontal shock tube and primary experimental results are obtained, which show the change of the turbulent mixing region clearly. |
