直到本世纪初,人们才认识到地球有几个圈层。根据卅年代布伦(K.E.Bullen)的计算和划分,地球可以粗略地分为三个圈层。其最外部是地壳,最内是地核,两者之间是地幔。此三圈层之间各有一分界面。本文只论述地壳和地幔之间的分界面,以下简称“分界面”。

Until the beginning of this century, people realized that there are several layers of the earth. According to the calculations and demarcation of K.E.Bullen in the nineteenth century, the earth can be roughly divided into three circles. The outermost part is the crust, the innermost is the earth’s core, and the mantle between them. There is a separate interface between the three circles. This article only discusses the interface between the crust and the mantle, hereinafter referred to as the “interface.”
