摘要
This paper briefly describes the definition of the normal gravitational field and the parameters that affect its value,compares the 1980 normal gravity formulae and CGCS2000 normal gravitational field parameters,makes a comparative analysis of the normal gravity and CGCS2000 normal gravitational field parameters used frequently in present gravitational exploration work,and deals with the necessity of popularizing the new normal gravity formulae in regional gravitational survey.
