A variational formula combining mixed finite element method with discontinuous finite element method is derived for solving the two group neutron diffusion equation in 2D. According to the variational formula, a numerical test is given whose result proves that the variational formula is reasonable and practicable. In order to improve the precision of the calculation, there are more to be studied.
