摘　　要：采用平面冲击压缩方法产生密度和温度都均匀的氩等离子体 ,根据辐射高温计记录和飞片速度的测定 ,通过阻抗匹配方法确定氩等离子体的Hugoniot物态方程 ,等离子体的温度为 1.4～ 2 .2eV ,密度为0 .0 0 83～ 0 .0 15 g/cm3 .应用Saha模型加Debye Huckel修正 ,计算了等离子体的Hugoniot物态方程 .测量值和理论计算结果符合较好 ,说明Saha模型加DebyeArgon plasmas with uniform density and temperature are generated by passage of a planar shock wave through argon gas. The EOS of argon plasma, covering the thermodynamic states at temperature of 1.4eV～2.2eV and in density of 0.0083～0.015g/cm 3, are investigated through measuring the emitted radiance versus time records .Comparisons of the measured EOS with the calculated ones demonstrate the Saha model can be used to describe well the essential behavior of argon plasma under the thermodynamic condition above mentioned. Authors' method of determining the EOS is different from Erskine's.
