The insulation characteristic of insulator in vacuum is researched in the process of the high voltage breakdown along the insulator surface in vacuum , which is called vacuum surface flashover 绝缘子的真空表面绝缘特性研究真空下的高压沿绝缘子表面击穿物理过程，称真空表面闪络过程。
Incondition of surface anti - corrision and insulation coat of metal and tiny hole of steel where resistance and crack is very small , when supplying a high voltage , gas crack will be punctured and electric spark discharging will occur , now send a pulse signal to the alarming circuit the alarmer can send out sound and light to alarm . we can do leak hunting on the coating according to this principle 金属表面绝缘防腐层过薄、漏铁及漏电微孔处的电阻值和气隙密度都很小，当有高压经过时就形成气隙击穿而产生火花放电，给报警电路产生一个脉冲信号，报警器发出声光报警，根据这一原理达到防腐层检漏目的。
The chemical composition and microstructures of the insulating thin films prepared by different methods were analyzed by x - ray diffraction ( xrd ) and scanning electron micrograph ( sem ) ; other properties such as electric resistance , the breakdown field strength and dielectric properties were evaluated using high resistance meter , voltage resistance meter and precision impedance analyzer respectively 采用x射线衍射仪( xrd )对表面绝缘薄膜的物相组成进行了分析,扫描电子显微镜( sem )对表面绝缘薄膜的微观结构进行了研究,并用绝缘电阻测试仪、耐压测试仪和精密阻抗分析仪分别对绝缘膜进行绝缘电阻率、击穿场强和介电性能的测试。
