摘要

在一级轻气炮加载下，利用光透射方法在线观测液体苯在多次冲击压缩下透光性的变化。结果表明苯在一次冲击加载时，透光性保持良好；二次冲击后，压力达到2.27GPa、温度543K时，苯的透光性开始出现下降；随着压力、温度增加，透光性下降更加明显。从相图可知，液态苯在二次冲击后进入苯Ⅱ相区，此时苯样品发生了结晶相变引起透光性变化。

Abstract:

Under gas-gun loading, the change of light transmittance of liquid benzene under multiple shock compression was observed online by light transmission method. The results show that the light transmittance of benzene remains good under the first impact loading; After the second impact, when the pressure reaches 2.27GPa and the temperature is 543K, the light transmittance begins to decline; With the increase of pressure and temperature, the light transmittance decreases more obviously. It can be seen from the phase diagram that the liquid benzene enters the phase region of benzene II after the second impact. At this time, the crystalline phase transition of benzene sample occurs, which leads to the change of light transmittance.

Key words: shock compression benzene light transmittance
