并利用转子支承都具有一定弹性的特点，通过改变转子支承刚度达到调整转子临界转速和振动形态的目的。
Then the critical rotate speed and vibration shape are changed by changing the supporting stiffness with the characters of flexibility of rotor.
因为石材翻新和晶面处理都需要一定重量的机器和特定的转速配合才能达到其晶面效果。
To ensure crystal effect, the stone renewing and crystallizing process requires the machine with some weight running at specific rotating speed.
