中文摘要：

战斗部装药内部孔隙是引起早炸的主要危险源。文中通过数值模拟研究发射载荷下孔隙内部的压力分布。为发射载荷下孔隙内部能量演化规律研究奠定基础。研究结果表明，发射载荷下对于同一个孔隙，孔隙内各点的压力大致相等。在对孔隙内的压力进行宏观分析时，可将孔隙内各点的压力看作相等。

英文摘要：

The voids in warhead charge explosive are main hazards causing explosion of charged explosive in the process of launch. The pressure distribution in a void in warhead charge explosive was studied by numerical simulation. The resuits show that the pressure in every place of a void under launch load is uniform. The pressure in the void under launch load can be considered as distributing uniformly.
