摘要

本文研究了基于FFT的二维拉普拉斯变换的数值反演方法。它的主要优点是计算速度快，但必须始终与适当的收敛加速技术相结合，才能达到所需的精度。已经证明，无论是epsilon还是商差算法都适合于此目的。本文对最优的NILT参数进行了误差分析、比较和评价。

Error analysis and optimal parameter evaluation in FFT-based 2D-nilt method

The paper deals with the method of numerical inversion of two-dimensional Laplace transforms based on a FFT. Its main advantage lies in high speed of calculation, however, it has to be always connected with a proper technique of the convergence acceleration to achieve the required accuracy. It has been shown that either the epsilon or quotient-difference algorithm is suited for this purpose. In the paper the error analysis, comparison and evaluation of optimal NILT parameters are canied out.
