摘要

摘要: 在二级轻气炮发射过程中，靶室内的残存气体和绕行到弹丸前方的推进气体都有可能对实验结果造成影响。利用石英传感器测量并得到了二级轻气炮高速弹丸发射时前冲气体的压力信号，并计算得到了相应的压力。实验结果表明：二级轻气炮发射时确实存在前冲气体现象，但其压力幅值较小，约为10-2 GPa量级，不会对高压物理实验的结果造成明显的影响。

Abstract: During the launch of hypervelocity projectile in the two-stage light gas gun, the remanent gas in target chamber and the pushing gas that leaks through the projectile might disturb the physical measurement of target sample. In this paper quartz gauges were used to detect whether the influence of such gases is in existence and how much it is. Our results show that the precursor gas exists indeed accompanied with the shoot of two-stage light gas gun, but its pressure is only about 10-2 GPa in amplitude and could not produce obvious influence to the usual high pressure experiments.
