摘　　要：精确地检测惰性气体的成分,对惰性气体进行加压电离,使之成为等离子体,通过光谱仪探测这些等离子体发光的特征谱线,进行数据的采集和分析,获取惰性气体的具体成分信息。Characteristic spectral line(spectrometric method)is a common method to measure the composition of plasma gas,which detects plasma signals by optical fibers,acquires and analyzes the data using a spectrometer.The purpose of this experiment is to accurately detect the composition of inert gases by the process of pressurized ionization to make it a plasma.These characteristic spectral lines of plasma emission were detected by spectrograph,and the specific composition information of inert gas was obtained based on data collection and analysis.
