“大地热流”等地热学重要术语的概念与应用

Concept and Application of Some Important Terms in Geothermics and Geophysics Such as Terrestrial Heat Flow

大地热流是地热学乃至地球物理学中的重要术语,在地球科学中的使用频率很高。与之近似的术语包括热流、热流密度、热通量、地表热流等。文章详细介绍了大地热流的定义、目前使用过程中存在的问题,以及在第二届地球物理学名词审定委员会对《地球物理学名词》修订过程中对相关术语定义所做的思考与取舍。

Terrestrial heat flow is an important term in Geothermics and Geophysics,which is frequently used in the Geo-periodicals.The synonyms include heat flow,heat flow density,heat flux and surface heat flow.This paper introduces in detail the definition of the terrestrial heat flow,the corresponding problems in its application,as well as the considerations and choices during the defining of the related terms in the second revision of Geophysical Terms.
