何转子在围绕其轴线旋转时，由于相对于轴线的质量分布不均匀而产生离心力。
When the rotor is rotating around its axis, the centrifugal force is produced because of the uneven mass distribution with respect to the axis.

When a rotor rotates around its axis, the centrifugal force is produced due to the uneven distribution of mass relative to the axis.
结果表明：对于一般的质量和刚度分布均匀的结构，人体对结构具有微弱的减振作用。
The results show that the vibration reduction effects of floors in the structure with uniform mass and stiffness are more obvious when the numbers of human occupants increase.
