Contact failure can occur when excessive heat or a high current or voltage pulse causes the contacts to weld together, resulting in short circuits.

当过热或者高电流或电压脉冲导致触点焊接在一起时，就会发生接触故障，形成短路。

Make sure the compliance voltage is high enough to avoid problems due to source contact non-linearity.

要确保输入端钳位电压足够的高，以避免由于源接点的非线性而产生的问题。

Instead, they make use of an inert gas, such as Xenon, which emits light when it comes in contact with a high voltage electrical arc.

相反，他们使用一种惰性气体，如氙，散发出淡淡的当它接触到高压电器电弧。
