The methods proposed in this paper can be easily applied to synthesize rotational and torsional components on free surface for aseismic design.
利用本文提出的方法可以方便地合成自由地表的扭转和摇摆分量，供抗震设计使用。

The results showed that no significant yield differences of standing forages were found in the rotational grazing area and in the closed area, which were all superior to the free stocking area.
轮牧和对照区群落现存量变化呈先增加，然后又下降的动态规律，自由放牧植物现存量几乎一直呈下降趋势。

The kinetic energy is distributed asymmetrically in the axial direction, and the asymmetry variation is a function of the rotational speed due to the influence of the free surface.
