| 摘 要： | 设计了一个以均匀网格差分模式为基础的变网格差分模式，如证明：如前者满足一定条件并具有质量和能量守恒性质，以及与连续情况一致的动，位能之间的转换关系，则变网格模式也同样具有，而且，把前者改变为后者增加的运算量很小，也非常方便。

| Abstract: | Based upon a uniform counterpart, a gridpoint model with variable resolution is presented. It has been proved that if the former model satisfies certain conditions, has properties of mass and energy conservation and keeps the conversion between kinetic and potential energy consistent to that in the continuous transformation, then the latter model will possess the same properties and conversion as well. Further, transforming the former into the latter needs a small amount of computational operation. |
