果冻内爆实验是一种研究柱形汇聚条件下Rayleigh-Taylor不稳定性的实验方法，由于高速摄影图像不能分辨反弹阶段果冻内界面的扰动，因此采用中低能X光照相CCD相机接收技术开展果冻与气体混合区域的实验研究，获得了果冻环在不同时刻压缩、反弹的发展状况及其内外边界，并观测到果冻质量分数降低时果冻与气体混合界面的变化。实验结果表明：X光照相可作为测量湍流混合区域的半定量测试技术，有助于研究果冻内爆中的气液界面Rayleigh-Taylor不稳定性现象。

Gelatin-ring experiment is a technique of studying Rayleigh-Taylor instability growth in a cylindrically convergent geometry. The customary measurement is the high-speed photography which is difficult to distinguish the turbulent mixing zone (TMZ). Therefore, the low and middle energy X-ray radiography system was conducted using the commercial flash X-ray tube and home-made camera. The evolutions of the gelatin-ring’s inner and outer surfaces were clearly observed by X-ray radiography in different time and gelatin’s concentration，including rebound of inner surface and turbulent mixing. The experimental results show that the process of the gelatin-ring’s TMZ can be distinguished by X-ray radiography. Therefore, X-ray radiography is an effective diagnostic in the gelatin-ring implosion experiment.
