| Abstract: | This paper derives that the two sufficient conditions to decide the mixed partial derivatives of two-component function are equal, it can be used to decide the problems that the mixed partial derivatives of two-component function are equal which can't decide them by schwarz's theorem. |

| Keywords: | Schwarz's theorem second order mixed partial derivative repeated limits |
