摘要
首先介绍了气压及其单位的变换,同时列举出重力计算中的许厚泽气压改正模型的几种不同表现形式,通过我国各地气压值共2046个数据统计绘制出气压改正值等相关等值线图,使其更加形象直观,便于检验计算。
In this article the contents introduce atmosphere pressure and the transformation of its unit,furthermore,list several formulas of XuHouze＇s atmosphere pressure adjustment model about gravimetry acculation.On the basis of 2046 statistic data of atmosphere pressure in various parts of our country the correlated equivalue maps of atmosphere pressure value are portraited so that it is easier to check up and calculate in the processing.
