【電】 nominal

1. 電路中的一個參考點，該點電位作為標(biāo)稱的零電位，其它所有電位均相對于該點而定。經(jīng)常，但并非總是，將該點直接連接到地。作為動詞，指連接到地線上的過程，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.
