In this paper, the causes producing the above mentioned phenomena are analysed and a correctionmatrix method is presented in order to compensate for the loss of significant figures.
本文分析了产生这一现象的原因，并提出了用校正矩阵法可以成功地补偿有效数字的损失。

Correction of matrix effect is a key part of XRF and, to a great extent, determines the accuracy of surveying data.
基体效应校正是X射线荧先分析方法中关键的一环，在很大程度上决定了测量数据的准确度。
