预闪 meaning in Chinese
preflash
Examples
- Fill flash , red - eye reduction ( via pre - flash ) , rear sync flash { wireless remote off - camera flash , high - speed sync available with program flash 5600hs ( d ) 3600hs ( d ) } , slow sync activated via ae lock button
强制闪光、减轻红眼闪光（透过预闪减轻红眼） 、后帘同步闪光{无线遥控分体闪光、使用programflash5600hs ( d ) 3600hs ( d )时可使用高速闪光同步} 、使用ae锁按钮可启动慢速闪光同步 - The experimental results show that the surface charging is related with the pre - flashover events , the pre - flashover events can bring the change of surface charge distribution . these may be attributed to the micro - discharge caused by the traps in insulator . the charge carriers can be captured by traps , a space electric field will be set up by the trap centers , and the combined electric field may exceed the breakdown electric field of local area , then the micro - discharge will be initiated
分析表明，反向预闪络现象与材料的陷阱分布有关，试样中电极附近的陷阱中心俘获载流子后所形成的空间电场的作用是产生这一现象的原因；预闪络现象和表面带电现象都是由于绝缘子表面陷阱中心俘获载流子形成空间电场造成局部场强过强引发的局部放电形成的。 - 2 . the pre - flashover phenomena of alumina insulators in vacuum have been investigated . according to the experimental results , a reversed pre - flashover current was observed repetitively , which often occurs at the tail of pulse voltage close to zero ( sometimes after the applied pulse voltage )
首次发现了大量的、重复性的反向预闪络现象，即在冲击电压波尾附近电压幅值已经接近零、甚至在冲击电压作用完后（已没有电压）的情况下仍然存在试样表面发光现象，同时伴有反向的电流脉冲。
