| 摘 要： | 通过光谱诊断系统测量了大气压直流氩等离子体射流在弧室内和弧室出口的发射光谱,利用波尔兹曼曲线斜率法计算了射流的电子温度,根据Ar Ⅰ谱线的斯塔克展宽得到射流的电子密度,并对氩等离子体射流满足局域热力学平衡(LTE)状态的判定标准进行了分析,结果表明在文章的实验条件下大气压直流氩等离子体射流达到局域热力学平衡. |

| Abstract: | The optical emission spectra of DC argon plasma at atmospheric pressure were measured inside and outside the arc chamber. The electron temperature was determined from the Boltzmann plot, and the electron density was derived from Stark broadening of Ar I lines. The criteria for the existence of local thermodynamic equilibrium (LTE)in the plasma was discussed. The results indicate that the DC argon plasma at atmospheric pressure under our experimental conditions is in LTE. |
