摘　　要：在57mm气炮上采用与电磁粒子速度计相结合的正向冲击和反向冲击两种实验构形及其相应的分析技术,研究了方解石晶体(初始密度为2.714g/cm3)的冲击压缩特性,获得了0.35～1.41GPa下方解石晶体的雨贡纽数据,确定了冲击波速度D与粒子速度u的关系.The experimental data of Hugoniot equation of state are provided for calcite (with the initial density 2.714 g/cm3) over a pressure range of approximately 0.35-1.41GPa. The experiment was conducted on a single-stage light-gas gun of 57mm. The reverse ballistic experimental configuration and the normal ballistic experimental configuration in combination with the electro-magnetic particle velocity gages and a set of analysis techniques were used in the experiment to understand the Hugoniot properties of calcite. On the experimental pressure range, the obtained linear relation between the shock velocity D and the particle velocity u of calcite.
