我们描述了声散射问题数值解的一些最新进展。本文的重点是用数值-渐近混合边界元方法有效地求解高频散射问题。我们还联系了A.S.Fokas和合著者提出的统一变换方法，分析了J.A.de-Santo和合著者针对衍射栅声散射问题提出的该方法的具体实例。
We describe some recent advances in the numerical solution of acoustic scattering problems. A major focus of the paper is the efficient solution of high frequency scattering problems via hybrid numerical-asymptotic boundary element methods. We also make connections to the unified transform method due to A. S. Fokas and co-authors, analysing particular instances of this method, proposed by J. A. De-Santo and co-authors, for problems of acoustic scattering by diffraction gratings.
