查询词典 flashover

This finding gives a good explanation to some experiment results which were not understood previously, such as"additional temperature effects"meaning that the flashover voltages after air density correction still increase with the decrease of temperature, and the increment of AC flashover voltage over an insulating surface caused by increase of unit absolute humidity is abnormally high, etc.

根据这一发现，可以很好地解释以往无法解释的一些试验结果，如所谓"温度的附加影响"，即同一绝对湿度对应的工频闪络电压，经过空气密度校正之后，仍随环境温度下降而明显增加。

Thus,in experiments of water mist flashover restraining, consideration only the mist decalescence in smoke and flame would be enough and doable.Nonlinear dynamics was chosen here for investigating water mist flashover restraining.

雾滴冷却汽油池火燃料表面效果不佳，因而在构建细水雾抑制轰燃预测模型时可以忽略燃料表面冷却，仅考虑雾滴在烟气层和火焰区的吸热效果。

Two kinds of silicon samples with distinct surface treatment, i. e., one surface was chemically etched and the other was unetched, were used to investigate the characteristics of leakage current and surface flashover of semiconductor under impulse voltage in vacuum. The experimental results showed that the surface conditions of samples affected these characteristics greatly. Before flashover, the Ohmic current was observed for unetched samples and the space charge limited current for etched samples, respectively. Meanwhile both samples showed quite different flashover tracks, and the surface-etched samples displayed a much higher onset voltage of flashover.

对采用和未采用表面化学腐蚀处理的半导体硅在冲击电压下的实验表明（参见 Zhang et al ， Applied Physics Letters， 2002），试品的表面状况对其泄漏电流和沿面闪络特性有着很大的影响：在沿面闪络之前，未经处理试品的泄漏电流表现为 Ohm 性电流，而表面处理过的试品表现为空间电荷限制电流特性；同时两类试品表面的闪络通道也表现出不同的特征，而采用表面化学腐蚀处理可以明显提高其沿面闪络电压。
