| 摘 要： | 以有限形式的存在性讨论、研究了Ｐｆａｆｆｉａｎ ｆｏｒｍ方程的可积性，建立了方程可积性的判别条件，指出原始条件只是存在积分因子的特殊情况。当方程没有积分因子时，该条件又给出了方程的有限形式。

| Abstract: | Through discussion of limited form's existence,this paper research Pfaffian form equation's integral quality,and sets up the determined condition of the equation's integral quality.Then it points out that the original condition is only a special case in condition of existence of interal factor.When the equation hasn't integral factor,the determined condition gives the equation's limited form. |
