Vorticity dynamics 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.
本文建立湿位涡方程、提出不守恒基本判据、分析不守恒运动的动力特征，尤其指出在湿中性层结区域非绝热加热和外作用力场对运动的激发作用。
