When switching low impedances, shielding needs are minimal. Shielding is generally needed only in electrically noisy environments.
在切换低阻时，屏蔽要求是最低的。通常只有在电噪声丰富的环境下才需要屏蔽。
Because of the high activeness of the titanium alloys, the inert gases or vacuum shielding is needed in fusion welding.
由于钛合金的活性强，熔化焊时需要用惰性气体或真空进行保护。
