本文提出了一个花岗岩中的多种微量元素发射光谱分析方法,叙述了方法的改进设想和两段曝光技术。本文也叙述了发射光谱的机理,给出一套为了发射光谱分析的最小二乘法线性回归方程。本文也讨论方法的精确度,分析结果表明它的精度对关于花岗岩的地球化学研究是好的。本方法对花岗岩的定量测定是简便、迅速和可行的。
This paper presents a method for the analysis of a variety of trace elemental emission spectra in granite. The improved method and the two-stage exposure technique are described. This paper also describes the mechanism of emission spectra and gives a set of least square regression equations for emission spectroscopy. The paper also discusses the accuracy of the method. The results of the analysis show that its accuracy is good for geochemical studies on granites. The method of quantitative determination of granite is simple, rapid and feasible.
