| 摘 要： | 本文提出了一种利用微机整谱拟合技术对多组分物相的红外光谱进行定性鉴定和定量分析的方法,阐述了该方法的原理和计算方法。通过与其它红外光谱定性和定量分析方法的对比,该方法不需选择特征峰,不需制备更多的标样。每种物相只需一个含量(重量)已知的标样即可分析。它能够一次性地对多种组分物相做出鉴定并提供其中每种组分的含量。该方法完全实现了计算机程序化,减少了很多人为的因素影响,提高了分析精度,并达到了方便实用的要求。

| Abstract: | The computer spectrum simulation technique is used to analyze the infrared spectra of mineral mixtures on the qualitative and quantitative bases. The principle of the method is discussed in this paper. In contrast to previous methods, this one doesn't need any characteristic peak and any more standard samples differing in weight (or concentration) with respect to each component of the mixture except for only one standard sample. The method can be used to identify each component of the mixture and, meanwhile its relative content can be obtained. The method is well programmed into computer and thus reduces artificial influence. So, the analytical accuracy is high and the method is very convenient and useful. |
