The N-S and Possion equations were calculated by using the velocity and pressure modification method at the same time. The surrounding current field at lower Renold number was then obtained.

同时采用速度压力修正法求解n - S方程和泊松压力方程，得到了雷诺数较低条件下的水平输油管线周围的流场分布。

Hence the N-Y ecotope and its surrounding areas should be considered to be the main direction of coalfield prediction and exploration in the region.

因此，N -Y生态区及其周缘地带应为该区煤田预测与勘探的主要方向。
