【摘要】 利用二级轻气炮装置研究了OP乳化剂的冲击压缩特性。二级轻气炮驱动铝/铜飞片至1 48～5 01km/s,冲击封装有待测样品的铝基板,用磁测速装置测量飞片速度,同轴电探针测量冲击波速度,在4 5～42 7GPa压力范围内获得了7个雨贡纽数据点。经分析发现,OP乳化剂在16 7GPa附近发生了冲击相变。更多还原

【Abstract】 The shock compression properties of emulsifier OP-10 were studied using a two-stage light-gas gun equipment. Aluminum target chambers filled with the samples were impacted by aluminum/copper projectiles accelerated by the equipment to a speed range of 1.48～5.01km/s.The flier speed was measured,in our study,with a magnetic velocity measuring apparatus.The propagating velocity of the shock wave was measured with coaxial electrical pins.Seven Hugoniot data at the pressure ranging from 4.5 to 42.7GPa were acquired.It could be concluded from our results that OP emulsifier underwent a phase transform at 16.7GPa.更多还原
