%X In this paper,a bubble stabilization of mixed finite element (MFE) approximation for second-order elliptic problems is discussed,and the priori estimate and posteriori estimate based on a simplified stabilized formulation are derived.This simplified stabilized formulation can save more freedom degrees than usual others formulation,for example,the same degrees element of the Raviart-Thomas method.
