中文摘要：
针对非线性抛物方程,给出了全离散的扩张混合元格式,利用一个建立在非重叠型区域分裂技巧上的并行迭代法求解了最后的非线性代数方程组,证明了迭代法的收敛性并给出了最优阶的误差估计.
英文摘要：
Fully discrete mixed finite element method is considered to approximate the solution of a nonlinear second-order parabolic equations.A massively parallel iterative procedure based on domain decomposition technique is presented to solve resulting nonlinear algebraic equations.The convergence of the iteration for each time step is demonstrated.Optimal-order error estimates are also derived.
