对“缪斯 - C”再入舱周围热化学非平衡高超声速流动进行了分析。还对整个再入舱进行了辐射分析。典型的再入速度在64千米高度时为11.6千米/秒。在如此高速的再入条件下，振动 - 电子温度以及强烈依赖于振动 - 电子温度的辐射热流对弛豫过程的模型非常敏感。特别是，电子弛豫过程和电子碰撞电离这两种机制占主导地位。
The thermally and chemically nonequilibrium hypersonic flow around the MUSES-C reentry capsule was analyzed. Radiation analysis all around the capsule is also performed. The typical reentry speed is 11.6km/s at the altitude of 64km. In such a high velocity reentry condition, the vibrational-electronic temperature and the radiative heatflux, which is strongly dependent on the vibrational-electronic temperature, are very sensitive to the models for the relaxation processes. Especially, the two mechanisms, which are the relaxation process for electron and the electron impact ionization, are dominant.
