测量了稠密氩等离子体温度,并与国外文献报道结果进行了对比。实验时通过对Ar气冲击压缩产生稠密Ar等离子体。Ar样品的初始压力均为0.1MPa,初始温度为293K。五个实验点的压力为0.125~0.163GPa,温度为23400~25900K,等离子体非理想性参数Γ为0.43~0.45。给出了Ar的Hugoniot冲击压缩数据及温度实测数据。理论计算首次考虑了二级电离效应,温度理论计算值明显地偏高于实验值,这说明用Saha加上DebyeH¨uckel修正模型的计算电离度已与实际结果出现了差别,其电离能和能级布居也发生了改变。
The temperature of dense argon plasma was measured and compared with the results reported in foreign literature. In the experiment, the dense Ar plasma was generated by impinging and compressing Ar gas. The initial pressure of Ar sample was 0.1MPa and the initial temperature was 293K. The pressure of the five experimental points is 0.125 ~ 0.163GPa, the temperature is 23400 ~ 25900K, and the plasma non-ideal parameter Γ is 0.43 ~ 0.45. Hugoniot impact compression data and temperature data of Ar are given. The theoretical calculation for the first time considered the second-order ionization effect, the temperature theoretical calculated value was significantly higher than the experimental value, indicating that the Saha with Debye H ¨uckel correction model has been calculated with the actual results of the degree of dissociation, the ionization energy And the level of population has also changed.
