By averaging the molecule velocity in the system,the sirnulation gives macro scopic flow description.

计算结果表明，薄膜中液体的等效粘度随着膜厚减小而逐渐增大，当膜厚减薄到一定程度时等效粘度急剧增加，流体完全丧失流动性。

The close time_space relationship between shoshonite in the northern part of Siziwang Banner and fluorite mineralization implies that the fluorite deposit might have resulted from the lithospheric thinning of eastern China and the replacement of the lower crust.
