三种逆矩阵型分层解释方法比较

THE COMPARISON OF THREE KINDS OF INVERSE MATRIX TE^-PE SUBDIVISION INTERPRETATION METHOD

本文较详细地叙述了逆矩阵法、组合逆矩阵系数法和逆矩阵系数法分层解释的基本原理。通过三种方法的模型解释结果对比，发现组合逆矩阵系数法和逆矩阵系数法，可以替代逆矩阵法。实验证明：组合逆矩阵系数法受底数影响小，而逆矩阵系数法计算简单、运算速度快。实际工作中，要求参加解释的底数占应尽可能多，解释时最好是去除底数。

This paper in detail illustrates the basic principle of inverse matrix method, combination inverse matrix coefficient method and inverse matrix coefficient method, (that is to say, the three kinds of subdivision interpretation method) After comparing the interpretation results of these methods on models, it is true that combination inverse matrix coefficient method and inverse matrix coefficient method can take the place of inverse matrix method。 Experiments show that combi nation inverse matrix coefficient method is influenced less by background activity and the calculation of inverse matrix coefficient method is simple and fast。In practice, it is necessary to have enough number points of background activity during interpreting; but it is best to remove background activity.
