| Abstract: | We discuss the theory problems of the asymptotical correctness of the error estimate and mesh selection rule,finally the numerical experiments demonstrate that the method not only results in less computational work but also appears to perform satisfactorily for singular problems in nonlinear ODEs. |

| Keywords: | singular boundary value global error defect correction |
