摘要
利用光谱诊断系统对空气直流电弧等离子体的发射光谱进行了测量。以CuⅠ波长在510.5 nm、515.3 nm、521.8 nm的3条谱线作为特征谱线,使用多谱线斜率法和Stark展宽法分别计算求得等离子体的电子温度和电子密度,并得到了直流电弧等离子体电子温度的空间分布规律。
DC arc plasma emission spectrums were measured by using the spectral diagnosis system. Three spectral lines of Cu Ⅰ with wavelength of 510. 5nm,515. 3nm and 521. 8nm are chosen as the characteristic spectrums. The electron temperature,the electron density and the spatial distribution regularities were obtained using the multi-spectrum slope method and Stark broadening,respectively.
