求翻译：我们构造网格上单元和边的基函数，接着采用方法，将此模型问题转化为一个线性代数方程组，从而转化为求解方程组的系数。最后，通过我们可以得到近似解与真解的误差估计以及收敛阶，从而验证了应用最低阶元的混合有限元方法的正确性与准确性。是什么意思？

We construct the grid unit and the side of the basis functions, then the use of the method, this model into a linear algebraic equations, and thus is transformed into solving the coefficients of the equations. Finally, we can get the approximate solution and the true solution error estimation and co

We build on the grid cell and the edge of the base functions, followed by method, this model will be a problem into a linear algebraic equations that can be translated into the equations of the coefficient. Finally, we can get by with an approximate to the truth of the error estimates, as well as co

On our structure grid the unit and the side primary function, then uses the method, this model question transformation is a simultaneous linear algebra equation, thus transforms as the solution system of equations coefficient.Finally, may obtain the approximate solution through us with the error est

We constructed on a grid basis function of the unit and, then, the model problem into a linear algebraic group, into a factor for solving equations. Finally, we can get error estimation of the approximate solutions and real solutions, as well as convergence order, so as to verify the correctness of
