经验系数法根据所用的经验校正方程类型和所希望分析的组分范围,一般需要相当多的优质多元标样。与此相比基本参数法则原则上仅需纯元素标样或单只多元标样。因为在有些情况下难于获得纯元素标样,加之若用单只多元标样可以消除或减少理论公式的不完善性从及基本参数的不准确性,因此使用单只多元标样更可取 The empirical coefficient approach, based on the experience used, corrects for the type of equation and the range of components that it is desired to analyze, generally requiring quite a few high-quality multivariate samples. In contrast, the basic parameters of the law in principle only pure standard element or a single multi-sample. Because it is difficult to obtain pure element standard in some cases, and if a single multiple standard sample can eliminate or reduce the imperfection of the theoretical formula and the inaccuracy of the basic parameters, it is preferable to use a single multi-standard sample
