Because of frequent setup and disassembly, cleaning and autoclaving steam sterilization, the steam is infiltrated into the ultrasonic handpiece, resulting in failure of electric insulation.
The getting of high - intensiting pulsed electric field(PEF), factor of PEF sterilization, and its acting mechanism was introduced in this paper.
对高压脉冲电场产生的原理，影响杀菌效果的因素，高压脉冲电场杀菌的有关理论进行了介绍。
