义务的履行是指债务人按照合同规定或者法律的规定充分履行义务。 它是债务最重要的影响，也是债务人最重要的义务。
债务的履行不同于付款和偿还。 受偿是指债务人应有的具体行为，常用于债务标的物，具有抽象的、静态的含义清偿是指债务人履行义务的效果，通常用于债务消灭的原因;而履行则是指债务人为履行债务内容而需要采取的具体行为，具有具体的、动态的含义。 债权人未通知债务人而分立、合并、变更住所，致使债务履行困难的，债务人可以中止履行或者交存标的物。

债权人可以拒绝债务人提前履行债务，但提前履行不损害债权人利益的除外。
the obligee may reject the obligor's advance performance of its obligations, except that the advance performance does not harm the obligee's interests.
债务人为提前履行对债权人的债务而产生的额外费用，由债务人承担。
any additional expense incurred by the obligee due to the obligor's advance performance of its obligations shall be borne by the obligor.
部分履行义务：
《合同法》第七十二条：
债权人可以拒绝债务人部分履行债务，但部分履行不损害债权人利益的除外。
an obligee may reject the obligor's partial performance, except that the partial performance of its obligations does not harm the obligee's interests.
债权人因债务人部分履行债务而产生的额外费用，债务人应当承担。
any additional expense incurred by the obligee due to the obligor's partial performance of its obligations shall be borne by the obligor.
