Objective To explore the effects and damages of low-temperature sterilizing with hydrogen peroxide gas plasma (HPGP) on dental high speedturbine handpieces, so as to prolong its service life.
Generally speaking, most of the wind turbine rotor is a rigid rotor, usually at lowspeed balance can be achieved and ensure the accuracy of the use of wind turbine rotor.
而一般来讲,大多数的风机转子都是属于刚性转子,通常在低速平衡就能达到和保证风机转子的使用精度要求。
