摘要
本文讨论了带有分片光滑系数的三维椭圆型方程的积分插值法,导出了相应的差分格式及误差估计式,证明了收敛性定理。
This paper discusses the integrating interpolation method to solve three- dimensional elliptic differential equation with piecewise smooth coefficient, giving the difference equation and the error estimates,proving the conve- rgence theorem.
