摘　　要：应用微分求积区域分裂法求解非线性奇异摄动问题。数值实验结果表明,该法准确度高,计算量少。In this paper, the differential quadrature domain decomposition method is applied to a kind of nonlinear singular perturbation problems. The numerical tests show that this method lead to high\|order accuracy at a cost of relatively small computational effort.
