火花

The grinding wheel sent a shower of sparks across the workbench.

砂轮迸出直落到工作台另一端。

It may limit the amount of sparkover to an acceptable rate.

它可把放电频率制在允许范围内。

What made the electric wire spark?

电线冒是什么原因?

Some sparks from a passing train set the haystack on fire.

一列过往车迸发出一些点着了干草堆。

The damp wood crackled and sparked.

In an impact matrix printer, it may also be termed a “needle” or a “wire” and in an electrosensitive printer or thermal matrix printer, an “electrode”.

在击打式点阵打印,它或许也可叫作“针”或“细棒”,而在电打印或热点阵打印叫作“电极”。

This heating helps to break down weak spots in the dielectric that otherwise might pass through the electrode undetected, only to fail during a later spark or hipot test.

这热量帮助击穿电线绝缘较薄地方﹐否线材通过电极而没有被检测到﹐结果在以后测试和高压绝缘试验将会失效。

His atrous eyes not only covered slightly by voile of blue but also with the bright sparkles which just appeared in kids' innocent eyes skipping when he raised up his head.

他那黝黑眼睛，虽然轻轻蒙上了一层忧郁纱，但当他抬起脸来时候，那乌黑大眼睛里却跳出了只有孩子天真眼睛里才有焰焰。
