流体微团运动
流体微团运动-
用拉格朗日观点考察了迁移加速度、粘性力以及科氏力在流动中的关系，发现在涡核中心以外，流体微团在运动过程中的加速旋转是由科氏力的作用引起的。
In the viewpoint of Lagrange , the relation of the remove acceleration , the viscosity force and the Coriolis force were analyzed . It shows that the particle acceleration was caused by the Coriolis force out of the vortex core during the vortex evolution .
