The earth is nonspherical and has a tilted axis.

地球不是球形的并有一倾斜的转轴。

For those who haven't heard the word, precession is when an object with a nonspherical shape wobbles around its rotation axis.

如果你还不了解&进动&这个词，进动指的是物体绕它的旋转轴有非球形的摆动。

The larger subharmonic component will be introduced into the system after the instability of system periodic motions, the motion of systems will be nonsynchronous precession and the amplitude of alternate stress in the rotor shaft is high. The long-term existence of instability will directly threaten the safe running of the rotor systems. Research on the influence of the change of system parameters on the system dynamical behaviors, the stability of system periodic solutions with the change of system rotational speed and the system motion after instability will have the theoretical and engineering-oriented significance for the long-term safe running of large-scale rotating machinery.

转子系统失稳后会产生较大的低频振动分量，系统运动出现非协调进动，系统转轴中会产生幅值很大的交变应力，转子失稳状态的存在直接影响系统的安全运行，因此研究转子系统自身参数的变化对系统动力稳定性的影响，研究系统周期解随工作转速的变化情况及其失稳后的运动规律，对大型旋转机械的安全稳定运行具有重要的理论意义和工程实用价值。

According to the characteristics of craftwork and micromark of quartzitic jade jues unearthed from the ancient tombs of Henglingshan site, in particular to a pair of the fine jade jues from the tomb M177, it is conjectured that the jade jues are made by the natives and the technology is employed in which fixed revolving axis in the centre when drilling a hole in jade materials, and the special fixed tools and rigid polishing materials would be used also in cutting and polishing processes.
