本文提出了一种新的计算离散汉克尔变换的简单算法，它不依赖于快速傅立叶变换。在某些类型的微分方程的解决方案，这种算法可以提供一个重大的改进，在速度和精度比以前描述的方法。本文给出了与电子散射中一类问题有关的输运方程的一种特殊形式的应用。
A new and simple algorithm for computing a discrete Hankel transform, which does not rely on the fast Fourier transform is described. In the solution of certain types of differential equations this algorithm can provide a major improvement in speed and accuracy over previously described methods. An application to a particular form of tile transport equation relevant to a class of problems in electron scattering is given.
