研究了一类赤道太平洋西部边界潜流的摄动机理.考虑了对应的广义控制方程.首先引入了一个优化的同伦映射,利用相应的映射求得了原模型的近似解.最后,通过一个例子说明了用同伦映射方法得到的近似解具有较好的精确度.
The perturbation mechanism of a class of subsurface flow over the western equatorial Pacific is studied. The corresponding generalized governing equations are considered. An optimized homotopy mapping is introduced and the approximate solution of the original model is obtained by using the corresponding mapping.Finally, The approximate solution obtained by the homotopy mapping method has better accuracy.
