perform a contract真的可以与fulfill a contract互换吗？

实行条约，我们稀有的表达有perform a contract, fulfill a contract等，在很多译文中，我们发觉这两种表达并没有作出严厉区分，但是二者在实行不同的条约职责时，其用法是有区别的。

perform的执法涵义是：to do what one party is obliged to do by a contract;

fulfill的执法涵义是：to do everything which is promised in a contract.

perform重申历程；fulfill重申后果，这与fulfill本身的涵义有关

因此，假如泛指各方在条约中的责任和职责的实行，则用perform；假如指条约一方实行其在条约项下对其划定的职责，则用fulfill。
