computation of elevation的意思|示意

The computation results showed that the effect of density differences when velocity of flow was small was obvious to the boundary of laminar flow in the elevation difference pipeline.

结果表明，在大落差管道，流速不大的情况下，密度差对层流边界层影响比较明显。

The analysis is divided into two parts: 1 computation of the velocity flow field and water surface elevation, and 2 computation of the pollutant concentration field from the dispersion model.

分析包括两个部分：1流场速度、水面高度的计算；2根据扩散模型计算污染物浓度场。
