摘要: 采用阻抗匹配法测量了两种低密度（0＝0.45 g/cm3和0＝0.47 g/cm3）硅橡胶在2.5~15 GPa压力范围内的冲击雨贡纽参数，p-up和us-up曲线，并采用最小二乘法拟合出C0，和的值。实验结果与理论预估值符合较好。Abstract: The shock-Hugoniots of two low-density silastic samples were measured by the impedance matching method in the pressure range from 2.5 to 15 GPa. The p-up and us-up curves were obtained. C0, and were calculated by using least square fitting. The experimental results are in reasonable agreement with the theoretical predictions.
