Abstract: This paper studies some elliptic PDEs with variable coefficients.By using the mixed finite element  method,the high-order differential equations are turned into the lower by middle varible.This paper verifies the existence and uniqueness of  the numerical solution and gives corresponding error estimation.

Key words: variable coefficients;mixed finite element method, middle varible
