摘　　要：基于牛顿的万有引力定律与静电场的库仑定律相似,均满足平方反比定律,对引力场的高斯定理进行了探讨.运用类比思想,引入虚引力场强度,提出了一种巧妙推导引力场高斯定理的新方法,并用该方法推导出引力场高斯定理的两种不同的表达形式,同时对此做出了相关的分析.理论表明该方法极其简单明了,易于理解和掌握运用,具有一定的推广价值.Based on the comparability between Newton＇s law of gravity and Coulomb＇s law in static electric field,which all follow an inverse-square law,the Gauss theorem in the universal gravitation field is discussed in this paper.Applying the idea of analogy,a clever new method to derive Gauss theorem in gravitation field is presented by introducing the virtual gravitational field strength.Two diferent expressions of Gauss theorem in the universal gravitation field are deduced using this method,and the relevant analysis is also given.It shows that the method is very simple and clear,and easy to understand and master,which has a certain popularization value.
