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 Learners Dictionary, the MerriamWebsters Advanced Learners English Dictionary, the Encyclopedic Dictionary of Applied Geophysics as SEGs 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
