| 摘 要： | 对高振荡积分而言，渐近方法只是在求积区间没有驻点时是有效求积方法．本文将这种方法推广到出现驻点的情形，数值实验也显示了这种方法的有效性．

| Abstract: | The asymptotic method is produced to do well with highly oscillatory integrals if there does not only exist stationary points. In this paper we extend this method to dell with the ease of stationary points and the experiments show their availability. |
