本文研究了方域上双调和方程Dirichlet边界条件的逼近问题。两种类型的离散问题，进行了数值分析，并给出精确解和近似解之间的误差估计。
This paper deals with the approximation of the biharmonic equation in a square domain with Dirichlet boundary conditions. Two types of discrete problems are presented, the numerical analysis is performed, and estimates for the error between the exact and approximate solutions are given.
