在对二次离子质谱的谱图的进行研究的基础上，提出了利用计算机进行二次离子质谱分析的数据处理方法，并已实现了其中的大部分内容．利用该方法处理复杂有机物的质谱图，可以自动输出不同有机物系列的质谱图，且易于分析，不受无机物和仪器噪音的干扰，还可以提取一系列的定量参数，节省质谱解析的时间，从而更好地分析有机混合物的组成及结构特征． Based on the study of the spectrum of secondary ion mass spectrometry, a data processing method using computer for secondary ion mass spectrometry analysis is proposed, and most of the content has been achieved. Using this method to process spectra of complex organic compounds, spectra from different organic series can be output automatically and easily analyzed without the interference of inorganic and instrument noise. A series of quantitative parameters can also be extracted to save the time of mass spectrometry analysis. Better analysis of the composition and structural characteristics of organic mixtures.
