说明：   摘要部分:这一快速算法的出现对数字 信号分析领域的发展起到了极大的推动作用。从此以后，它作为频谱分析的基础得到了 由于计算机只能对信号的有限多个样本进行计算.
(Abstract : The Fast Algorithm for the emergence of digital signal analysis of the development of the field will play a great role in promoting this. Since then, spectrum analysis as the basis for the computer to signal only a limited number of samples for calculation.)
