摘　　要：采用Saha方程加Debye-Hückel修正简单近似模型,给出了稀有气体He,Ne,Ar,Kr,Xe在电离区的物态方程以及离化度.计算结果与已有实验和理论计算进行比较,验证了模型的可靠性.通过对稀有气体等温和冲击压缩特性理论分析,讨论了其压缩和电离的规律性.论证了在稀有气体He,Ne,Ar,Kr,Xe中,气体Xe具有较好的抗压缩性。The equations of state and ionization degrees of helium,neon,argon,krypton,and xenon in the region of ionization have been presented based on the Saha equation with the Debye-Hückel correction.The calculated results were compared with the experimental data and other calculations and the reliability of this model has been validated.The compressibility and the regularity of ionization were discussed by the calculated isotherms and shock compression curves of the rare gases.The results indicate that xenon has better compression resistance among the gases cousidered.
