摘要：


摘要：文中指出权威英文词典在物理场定义上的误导并加以澄清。《朗文现代高级词典》(Longman Modern English Dictionary),《朗文当代高级词典》(Longman Dictionary of Contemporary English),《牛津高阶英汉双解词典》(Oxford Advanced Learners EnglishChinese Dictionary),《韦氏词典》(MerriamWebsters New Collegiate Dictionary), 作为美国勘探地球物理学会(SEG)名词术语,特别是地球物理名词术语标准的《勘探地球物理百科词典》(Encyclopedic Dictionary of Exploration Geophysics)和《应用地球物理百科词典》(The Encyclopedic Dictionary of Applied Geophysics),以及中国的一些地球物理教科书、专著及词典,把物理场定义为物理作用或效应存在的空间或区域,不同于物理学中场论及国外地球物理文献的定义:空间中存在的作用或效应。定义物理场为物理作用或效应存在的空间,混淆了物理“场”本身及“场域”的概念,不是一个标准的物理学定义。建议物理场定义为:空间中存在的物理作用。

Abstract:

 This paper clarifies a misleading in the definition of physical field made by authoritative English dictionaries. The Longman Modern English Dictionary,  the Longman Dictionary of Contemporary English, the Oxford Advanced Learners Dictionary, the MerriamWebsters Advanced Learners English Dictionary,  the Encyclopedic Dictionary of Applied Geophysics as SEGs standard for terms particular to geophysical technology,  Chinese geophysical textbooks, monographs, and dictionaries  have defined physical field as an area, a space or a region. The definitions differ significantly from another definition in the theory of fields and another geophysical literature, which is usually given as an effect or a force. Defining the physical field as an area, a space or a region confuses the field itself with the space throughout which the field exists, and is not a standard physics definition of a field. A new definition of the physical field based on the theory of fields is proposed as follows: a physical effect existing in a space.

Key words: physical field, gravity field, definition
