首先针对离散情况，对守恒重映中的“守恒”给出数学上严格的解释.在此基础上，对守恒重映问题中所固有的守恒量协调问题作了描述，并提出一种基于最小二乘法的处理方案.同时，还分析了容易混淆的“质量密度”和“体积密度”，网格中心量和网格节点量等基本概念，并采用两种不同的辅助网格来对网格节点量进行重映.

The strict explanation about conservation on discrect sitiuationis given at first.Then the dilemma among different conservative variables are discussed,and a least squart method is presented to solve it.Some easily confused concepts about conservation are analysed in detail.
