摘要
假设空气是量热完全气体，从冲击波阵面上的质量、动量和能量守恒方程出发，推导出12个冲击波有关物理量与冲击波Mach数之间的正、反关系式，这些物理量包括静压力、密度、流速、温度、声速、当地Mach数、动压力、反射压力、反射温度、反射声速、总压力和熵。研究结果对爆炸流场参数的测试、数据分析及其他相关研究具有重要意义。
In order to establish links among the physical variables related to the shock wave, assuming that the air is a calorically perfect gas, twelve relationships between the physical variables related to the shock wave and the shock Mach number are deduced from the equations representing the conservation of mass, momentum and energy across the discontinuity. These physical variables include the static pressure, density, flow velocity, temperature, sound velocity, local Maeh number, dynamic pressure, reflected pressure, reflected temperature, reflected sound veloci- ty, total pressure and entropy. These findings are of great significance for testing, data analysis of blast flow field parameters and other related research.
