中文摘要：
在气体炮加载实验平台上，搭建了一套瞬态激光拉曼光谱测量系统，并用于苯的冲击压缩瞬态拉曼光谱研究。实验中观测到，在0．8～3．0GPa压力范围内苯的C—H伸缩振动峰（3061cm-1）的频移随压力呈线性变化，其结果与其它文献报道吻合。实验表明，该测量系统稳定，可重复性好，为研究透明及半透明物质在动态加载实验中的微观结构变化提供了一种有效手段。
英文摘要：
A new measurement system for transient Raman spectroscopy under gas-gun loading and the Raman spectra of shocked benzene have been reported in this paper. The experimental results show that the Raman shifts of C--H stretching mode （3 061 cm-1） are linearly dependent of shock pressure between 0.8 GPa and 3 GPa. The extrapolation of the present results agrees well with the published experimental data. It shows that the new measurement system has good stability and repeatability, and it is an effective method to study the structural changes at the molecular level of transparent and semi- transparent materials under dynamic loading conditions.
