请问，这个怎么翻译？
<P>请问，下面几个怎么翻译？</P><P>leading edge spike</P>
<P>duty cycle</P>
<P>gas jet assist</P>
<P>gas transport</P>
<P>keyholing</P>
<P>rapmer</P>
<P>power ramping</P>
<P>谢谢~~~~~~~~~~~~~~~</P> <P>leading edge spike</P><P>duty cycle</P><P>这两个词组没用过,不好随便翻译.看一句话应该可以理解.</P><P>gas jet assist :气体喷射辅助,(assist gas)就是辅助气体的意思.</P><P>gas transport:气体运输.</P><P>keyholing: 锁眼,一般在焊接时,先产生一个锁眼, 也叫keyhole welding</P><P>power ramping :就是把输出的能力变成各种各样的阶梯形输出.</P> <P>leading edge spike 前沿尖峰</P><P>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。</P> 太谢谢你们了！！！！！！！！！！！！！ <P>楼上1241得哪一位？？？？</P> <P>duty cycle 叫做 负载循环</P><P>leading edge spike 叫做脉冲尖峰</P> 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。
