HR2 steel was shocked and the spall samples were obtained by using a light-gas gun and "sample soft-capture" technology.
利用轻气炮加载和样品软回收技术，对HR2钢进行了试验，获得了软回收层裂样品。
The dynamic behavior of HR2 and DT2 under explosive load were also studied in this paper, and the damage phenomena like spallation were analyzed.
本文还对化爆加载下的HR2和DT2等进行了实验研究，对实验研究过程中出现的层裂等损伤现象进行了分析。
