Based on the potential theory, a linearity combination of the disturbanceflow field generated by the uncompressible vortex part was applied in the computation of separate vortex flow.
以势流理论为基础，本文用不可压流涡段所产生的扰动流场的线性叠加，计算涡分离流动的流场。

This implies that the disturbance increases with distance along the axis of the swirling flow, but it does not grow with time.
这一假定意味着扰动沿涡旋流动的轴向随距离的增长而增长，但不随时间而增长。

Compared with the spacecraft instrumentation, the ground air disturbance, the unsteady aerodynamic flow on crossing event and inside tunnel impose more challenges on the head design of HSR trains.
