| 摘 要： | 将库检索与目标转换因子分析相结合利用抽象浓度的分布信息确定可能解域，其最大可能解即为体系包含的物种。可能解域的确定大大减少了计算量，应用于严重重叠的甲苯和乙苯二组份和苯，甲苯及乙苯三组份混合体系，结果令人满意。

| Abstract: | In this paper, a new method combining target transformation factor analysis and spectral library searching (LS) was developed for qualitative analysis of mixture from IR da- ta. At first, possible solution fields were determined from distribution of abstract concentra- tion. Then, by use of LS, the most possible solution from every field as components of the system was chosen. The method was used in actual two-component (benzene and toluene) and three-component (benzene, toluene and ethyl benzene) systems in which characteristic peaks overlapped greatly. The result was satisfactory. |
