Rader's algorithm, exploiting the existence of a generator for the multiplicative group modulo prime N, expresses a DFT of prime size n as a cyclic convolution of size N 1, which can then be computed by a pair of ordinary FFTs via the convolution theorem (although Winograd uses other convolution methods).
Rader演算法提出了利用点数为N的DFT进行长度为N-1的回旋摺积来表示原本的DFT,如此就可利用摺积用一对基本的FFT来计算DFT。

This study consists of three parts. Firstly the equivalently accelerative corrosive environment is determined through the analysis of statistic data of corrosion environment. Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years. Four S-N curves with different corrosive time are obtained based on the fatigue experiment. Finally the regression method of S-N curves for experimental data is researched and a weighted least square fit is put forward in which the weigh of a group of test data is inversely proportional to the length of the confidence interval.
进行了以下几个方面的工作:(1)通过实测、统计、分析得到了当量加速环境谱;(2)完成了在当量加速环境谱下预腐蚀日历年限0年、3年、8年和13年的腐蚀试验,并进行了成组常幅疲劳试验,得到了不同预腐蚀年限下的S-N曲线;(3)进行预腐蚀后的S-N曲线的数据拟合方法的研究,提出了考虑置信区间长度影响的加权最小二乘法。

In chapter 1 ,on one hand ,we give some sufficient conditions for a finite group to be supersolvable and nilipotent by using the properties of π-supplemented subgroups;For example: Theorem 3 Let G be a group, 2 ∈π, if every subgroup of G of prime order is contained in SE, every cyclic subgroup of G of order 4 is π-supplemented in G, then G will be supersolvable.
