discharge在法律英语中的常用含义有两个，而且是意思相反的两层含义：

(1)履行，侧重于对具体义务的履行；

(2)免除，即免除他人的义务或债务等。

因此在翻译其含义时，要结合上下文，选择准确的意思。

例句一：

He discharged his obligations after the call of the creditors.

他在债权人的督促下履行了自己的义务。

例句二：

His liability to pay the loan to the bank was discharged due to his bankruptcy.

他对银行的借款偿还义务因其破产而免除。
