高温高压下爆轰产物分子间相互作用的研究
Pair interactions of detonation products at high pressure and high temperature

摘要: 给出了一种由分子流体的冲击Hugoniot实验数据确定原分子之间和离解产物分子、原子相互间作用势参数的方法.在较低压强下,采用Ross硬球微扰理论软球修正模型确定原分子之间的相互作用势参数;在较高压强下,采用基于统计物理的化学平衡方法来确定分子离解后的分子和原子之间的相互作用势参数.与传统的由对应状态定律确定势函数参数的方法相比,所得到的势函数参数在很大的压强范围内都能较好地描述冲击实验.

Abstract: In this paper,we present a method of determuning the potentials of molecules and dissociation products by shock wave data.The potentials are calculated by the Ross's modification of hard-sphere variation theory at low pressure and the statistical mechanical chemical equilibrium method at high pressure.Our results are in better agreement with the experimental data than the results obtained from the corresponding states theory. -
