| 摘 要： | 山区重力测量工作中,用现有方法计算总均方误差,往往使均方误差偏小,异常的可信程度降低。这主要原因是山区重力工作中,忽略了影响较大的岩石密度的误差。而要准确的测定各部分岩石密度又是十分困难的。据此,本文分析了山区重力测量总均方误差的来源,提出了各项误差分配的方法。

| Abstract: | The total mean square error for gravity survey in mountainous region estimated by the present methods are usually too small to be convincing. The main cause is that the density errors of rocks which may produce great influence is negelected in moun-tainous region gravity surveys. It is difficult to measure the density of rocks precisely at every part of the mountain region. In the present paper, analysis of the origin of the total mean square error for gravity survey in mountainous region is given, and method for the estimation of the distribution of various errors is presented. |
