Based on lots of video observation tests, there are three motion states of grinding medium in a mill tube, including projection, revolution and autorotation. The movement cycle of grinding medium departing from and contacting with the inner liner is equal to the vibrating period.

在对大量摄像实验反复观测和研究后发现：磨筒内的磨介存在抛射、整体回转和本身自转3种运动状态；磨介与筒壁的抛离与接触是沿着振动方向发生的，此过程是周期性的，其周期与振动周期相同。

The biggest worry is not recession, which is cyclical,' says Willie Fung, chairman of brassiere manufacturer Top Form. Instead, he says, it is the 'one way' changes in China's operating environment.

文胸生产商黛丽斯国际有限公司的主席冯炜尧说，最大的问题并不是美国经济可能出现衰退，那只是周期性的，而是中国经营环境的"单向"变化。

Inspirited periodically by means of centrifugal inertial force, the lopsided rotor will produce coercionary vibration and inordinate noises, accordingly result in the exacerbating of the working conditions. At the same time, the components of the axletree will wear down quickly, that has reduced the natural life and working efficiency.

由于周期性的离心惯性力对转子的激励作用，不平衡转子将产生强迫振动和过度噪声，从而导致工作环境恶化，加速轴承等零部件的磨损，降低机器的使用寿命和工作效率。
