摘要：

We present a method for solving a class of initial valued, coupled, non-linear differential equations with 'moving singularities' subject to some subsidiary conditions. We show that these types of singularities can be adequately treated by establishing certain,moving' jump conditions across them. We show how a first integral of the differential equations, if available, can also be used for checking the accuracy of the numerical solution. (C) 2002 Elsevier Science B.V. All rights reserved.
