摘　　要：高温空气状态方程在大气层核爆炸、卫星发射与航天器再入、强激光与大气作用等国防高科技中具有广泛地应用;讨论了含化学反应、分子离解、原子电离等过程的高温空气状态方程计算方法,且计算过程中考虑高温等离子体带电粒子间,库仑相互作用对高温空气状态参数的影响;提出的迭代数值计算方法,可有效地求解非线性方程组,计算结果与文献报道的数据符合良好.The equation-of-state for high-temperature air is widely used in high-tech researches of national defence, the high-tech researches include aerosphere nuclear explosion, satellite transmitting, space reentry, high-power laser and so on. In this paper, the calculating method of equation-of-state for high-temperature air is discussed. Chemical reaction, molecular decomposing, atom ionization, and influence of electriferous particle Couloumb reciprocity existing in high-temperature plasm is considered in the calculating process. By iterative computation method presented in this paper, nolinear equation group is efficiently evaluated, and the results are in a greement with the previous.
