外文摘要：This paper aims to asymptotically evaluate a class of integrals involving products of two oscillatory Bessel functions. By leveraging the properties of multiple integrals and integration by parts, we develop an approximation method for these integrals. Numerical examples are provided to validate the theoretical results and demonstrate the efficacy of the proposed approach.
