Applicated exterior differential to function of two variables, differential form of real function on Green theorem was gained. Through the real converted into complex, and by using exterior differential properties, differential form of real function on Green theorem was gained, too.%通过对二元函数利用外微分性质,得到实函数Green定理的微分形式。通过实复转换,并运用外微分性质,得到复函数Green定理的微分形式。
