| 摘 要： | 重叠峰解析是目前分析化学中亟须解决的一个重要问题，化学计量学用于重叠峰解析就是借助某些数学或统计学方法，把通过化学方法和仪器未能完全分离的复合量测信号分解成几个单儿组分的信号，从而从重叠谱中获取每个组分的相关信息。本文综述了几种常见信号处理技术在重叠化学信号分辨中的应用，引用文献146篇。

| Abstract: | Chemical signals are always multi component systems since measurements related to the chemical composition of a substance are very complex. As a result, resolving or recovering overlapping bands has become a crucial problem encountered in analytical chemistry. Chemometrics is the discipline concerned with the application of statistical and mathematical methods, as well as those methods based on mathematical logic to chemistry. It is an alternative technique for resolving overlapping bands that cannot be instrumentally and physically resolved. In this paper, some signal processing techniques for resolution of unresolved bands are reviewed with 147 references. |
