| 摘 要： | 电弧等离子体是非均匀等离子体，其内部进行着复杂的能量和质量输运过程，等离子体的温度测量具有重要意义。Boltzmann作图法测量温度较谱线绝对强度法、标准温度法等测温方法更为方便。基于Boltzmann作图法原理，对TIG电弧进行实时的空间扫描，分析了谱线的选取原则，测量计算出TIG焊电弧等离子体的温度场分布。

| Abstract: | Arc plasma,as non-uniform plasma,has complicated energy and mass transport processes in its internal,so plasma temperature measurement is of great significance.Compared with absolute spectral line intensity method and standard temperature method,Boltzmann plot measuring is more accurate and convenient.Based on the Boltzmann theory,the present paper calculates the temperature distribution of the plasma and analyzes the principle of lines selection by real time scanning the space of the TIG arc measurements. |
