Vorticitydynamics is a good break point when researching unsteady aerodynamics.
涡动力学是研究非定常空气动力学的一个有力切入点。

The kinematic vorticity number (W_K), which is introduced into geology from fluid dynamics, is used to measure the degree of non-coaxiality of strain.
运动学涡度是从流体力学引入到地质学当中的，主要应用于应变非共轴程度的确定。

In this paper a set of equations of wet potential vorticity is founded, the basiccriterion of non-conservation is set up, and the dynamics character of the non-conservationmotion is analysed.
