四個專業技術名詞懸賞請教好答案

jiming

1.recurrent peak reverse voltage, RMS voltage翻譯成中文是什麼?

2.這句話如何翻譯“R12,R13 are currently DNP” 是Data Not Possible? or Do not place？有的datasheet寫open，一個意思，就是不放置？

3.low forward voltage 翻譯成中文是什麼意思? 是低壓降？是一般用來描述二極體的？那請問Vz是不是指穩壓二極體能穩的電壓值?

4.lower dropout voltage 翻譯成中文是什麼?  是低壓差？

另外，附送一則 Hilarious Quote！能提出好解釋說明者，另有重賞！

When a naked man is chasing a woman through an alley with a butcher knife and a hard-on, I figure he isn't out collecting for the Red Cross.

- Clint Eastwood in "Dirty Harry"

Thank you, Mr. Eastwood, now I realize when the Red Cross is collecting donations on the street, they don’t hold a butcher knife.
