The structure of planar shock waves propagating through argon, xenon, and krypton is calculated using the direct simulation Monte Carlo method for Mach numbers 2, 5, and 10. The upstream temperature considered in the present paper varies from 30 to 8000 K, depending on the gas species and Mach number. Both quantum and classical approaches to the intermolecular collisions based on ab initio potential are used. The distributions of density and temperature inside the shock wave are reported. The density slope is calculated as a function of the upstream temperature and Mach number with the numerical error less than $$0.5\%$$ . The dependence of the density slopes on the upstream temperature is studied. It is shown that the slope behaviors of the heavy gases are qualitatively similar to each other, but they are completely different from those for helium.

通过重惰性气体传播的冲击波结构：温度依赖性

通过氩气、氙气和氪气传播的平面冲击波的结构是使用直接模拟蒙特卡罗方法计算的，马赫数为 2、5 和 10。本文考虑的上游温度从 30 到 8000 K 不等，具体取决于气体种类和马赫数。使用基于从头算势的分子间碰撞的量子和经典方法。报告了冲击波内部的密度和温度分布。密度斜率计算为上游温度和马赫数的函数，数值误差小于 $$0.5\%$$。研究了密度斜率对上游温度的依赖性。结果表明，重气体的斜率行为在性质上是相似的，
