摘要: 针对高压产生装置金刚石对顶砧合成的含能材料样品量少, 难以满足测试设备对样品量下限的需求, 以及高压合成的样品不易从样品腔中剥离出来, 难以采用已有设备对样品进行表征的问题, 设计并自主搭建一套可实现对微米样品开展可控激光刺激随时间响应状态的观察系统, 并利用该系统对部分含能材料进行测试. 结果表明, 该系统可有效记录含能材料的受激爆炸过程, 实现对微米量级含能材料的引爆观察, 提供一种对含能材料含能特性较直观的判断方法.

Abstract: Aiming at the problem that the amount of energetic material samples synthesized by diamond anvil in the high-pressure generating device was small, it was difficult to meet the needs of the test equipment for the lower limit of sample volume, it was difficult to separate the high-pressure synthesized samples from the sample cavity, and it was difficult to use the existing equipment to characterize the samples. We designed and independently built an observation system that could achieve 
controllable laster stimulus response over time for micrometer samples, and used the system to test some energetic materials. The results show that the system can effectively record the stimulated explosion process of energetic materials, realize the detonation observation of micron-level energetic materials, and provide a more intuitive method for judging the energetic characteristics of energetic materials.

Key words: observation system of response process, energetic material, high-pressure, laser
