利用同伦映射理论研究了一类广义鸭解系统.首先引入一组同伦映射,然后构造了原系统解的迭代关系式.最后得到了问题鸭解的近似解析式.
Using the homotopic mapping theory, the approximations of the solution for gen- eralized canard systems are obtained. Firstly, introducing a set of homotopic mapping. Then the iteration expressions of solution for original system are constructed. Finally, the analytic expressions of the canard solution for problem are obtained.
