percussive maintenance 敲打式维护

Percussive¹ maintenance refers the use of physical concussion², a knock or a tap, in an attempt to make a malfunctioning³ device work instead of asking for professional help.

“敲打式维护”指设备有故障的时候，不找专门的维护人员，而是用敲打的方式让其恢复运转。

 

Percussive maintenance happens when your piece of electronic device -- television, computer, etc -- won't work, you give it a sharp unscientific whack⁴ to revive it. And it often works.

电视或电脑等电子设备出故障的时候，你有时会通过敲打的方式让其恢复运转。而且这种方式通常都会管用。
