摘要
对源于传输带上流体边界层中的一类奇异边值问题进行了研究．利用单调逼近方法得到了满足物理意义上负解的存在性、惟一性的充分条件及壁摩擦应力估计式．利用打靶法技巧得到了问题的数值解．
A class of nonlinear singular boundary value problems were studied for the boundary layer of fluid flowing on a conveyor belt. Sufficient conditions for the existence and uniqueness of negative solutions to the problems were established by utilizing the monotonic approaching technique. The numerical solution was presented by using the shooting method.
