请问，这个怎么翻译？

请问，下面几个怎么翻译？

leading edge spike

duty cycle

gas jet assist

gas transport

keyholing

rapmer

power ramping

谢谢~~~~~~~~~~~~~~~

leading edge spike

duty cycle

这两个词组没用过,不好随便翻译.看一句话应该可以理解.

gas jet assist :气体喷射辅助,(assist gas)就是辅助气体的意思.

gas transport:气体运输.

keyholing: 锁眼,一般在焊接时,先产生一个锁眼, 也叫keyhole welding

power ramping :就是把输出的能力变成各种各样的阶梯形输出.

leading edge spike 前沿尖峰

duty cycle 负载循环 不过还有别的意思，看你是用在哪里了，可以说是频宽比，有荷系数，填充系数，暂载率。

太谢谢你们了！！！！！！！！！！！！！

楼上1241得哪一位？？？？

duty cycle 叫做 负载循环

leading edge spike 叫做脉冲尖峰

Duty cycle is the proportion of time during which a component, device, or system is operated. The duty cycle can be expressed as a ratio or as a percentage. Suppose a disk drive operates for 1 second, then is shut off for 99 seconds, then is run for 1 second again, and so on. The drive runs for one out of 100 seconds, or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent.

也叫占空比。
