摘要： 采用速度调制分子离子激光光谱技术，通过研究光谱信号的线宽及强度对实验参量的依赖关系，可以诊断辉光放电等离子体中的温度和电场等参量，进而可获得辉光放电中的离子浓度.作者从理论和实验两方面研究了辉光放电中的离子浓度，两者吻合得非常好，表明速度调制分子离子光谱技术可以很好地实现对等离子体浓度不介入诊断.

Abstract: The density of molecular ions together with the temperature and the electric intensity in the positive column can be diagnosed when studying the dependence of spectral intensity and line-width on some experimental parameters by velocity modulation spectroscopy. The ionic density was theoretically and experimentally studied in this paper, and the good agreement suggests that the velocity modulation spectroscopy can non-intrusively diagnose the ionic density in plasma.

Key words: ionic density, velocity modulation, diagnosis, ionic density, velocity modulation
