【電】 nominal

1. 電路中的一個(gè)參考點(diǎn)，該點(diǎn)電位作為標(biāo)稱的零電位，其它所有電位均相對(duì)于該點(diǎn)而定。經(jīng)常，但并非總是，將該點(diǎn)直接連接到地。作為動(dòng)詞，指連接到地線上的過(guò)程，也稱作接地。
   A point considered to be at nominal zero potential and to which all other potentials in the circuit are referred, often, but not always, connected to the actual surface of the earth; as a verb to connect to a ground. Also called earth.
