含双参数的半线性奇异摄动问题的一致收敛差分格式

In this paper, a difference scheme for solving a semilinear singular perturbationproblem with two small parameters is presented. It is shown that the solution ofthe scheme converges, uniformly in perturbation parameters, to that of the contin-uous problem. A numerical example is given.
