When the motion of the basic state is the shear flow (or the differential rotation), this property means that the unstable waves would evolve automatically into the quasi-stationary stage.
当基态运动为剪切流(或较差旋转)时，这一性质将使不稳定波自动演化到准稳阶段。
Through the mechanical analysis, the differential equation for the longitudinal deformation of cold forming steel is derived, and the formula for longitudinal rotation Angle is obtained.
对冷弯型钢的纵向变形过程进行了力学分析，得到了变形微分方程，求得了转动角的理论公式，并对其变形形状进行了分析计。
These preliminary results give us a possible hint to study some global tectonic phenomena, e. g. the asymmetry of the southern and northern hemispheres and the earth's differential rotation.
目前的工作还只是初步的，但为我们探讨全球大地构造上的某些现象，例如南北半球的不对称性和差速旋转问题提供了一种可能的研究思路。
