推导了任意个源区混合时同位素和微量元素所必须满足的普适方程；以二元混合作用为例详细讨论了在不同的条件下（比值-比值、比值-元素、比值-1／元素、元素-元素）该方程的展开和简化形式。从三元混合方程的展开形式可以看出，“地慢面”的概念是不能成立的，同时大洋玄武岩Nd，Sr和Pb同位素组成数据也并不支持大洋玄武岩为三元混合作用所形成这一假设。
The general equations which must be satisfied by isotopes and trace elements in mixed source regions are deduced. Taking the binary mixture as an example, the effects of different conditions (ratio - ratio, ratio - element, ratio -1 / element, Element - element) The expansion and simplification of this equation. From the unfolding of the ternary mixed equation, we can see that the concept of “slow ground” can not be established. At the same time, the data of Nd, Sr and Pb isotopic composition of the oceanic basalts do not support the formation of ternary mixture by the oceanic basalt Assumptions.
