無電壓,零電壓

Now RCM and CCM of channel 1 HI have no voltage across them. 現(xiàn)在，通道1的HI線路上的RCM和CCM上沒有電壓。

Nanovoltmeters and nanovolt preamplifiers will rarely indicate zero when no voltage is applied to the input, since there are unavoidable voltage offsets present in the input of the instrument. 當(dāng)輸入端沒有施加電壓時(shí)，納伏表和納伏前置放大器很少會(huì)指示零讀數(shù)。這是因?yàn)樵趦x器的輸入端不可避免地存在著電壓偏置。

Ideally, when a voltmeter is connected to a relatively low impedance circuit in which no voltages are present, it should read zero. 在理想的情況下，當(dāng)把電壓表連接到一個(gè)沒有電壓的、阻抗比較低的電路時(shí)，電壓表的讀數(shù)應(yīng)當(dāng)為零。

Whether it rains or not makes no difference to me. 下不下雨對我來說都一樣。

The cruel landlord would bate him no rent. 那個(gè)狠心的地主不肯給他減租。
