摘要
把求解区域分成若干个子域，在不同子域中采用不同的计算步长。对二维变系数的椭圆型，抛物型和双曲型方程分别给出格式，得到了收敛性和误差估计。
A domain decomposition algorithm for numerically solving the parabolice-quation,hyperbolic equation and elliptic equation in two space dimension is presente.The coeff-icences of there equations are varied with space variables,The different meshes are applied to the finite difference in subdomains. Average norm error estimates for equations are derived.
