In this paper,at the first,we investigate the properties of X'mantissa domains;obtain that there are four kinds of mantissa domains[X~(44-2)],[X~(44-1)],[X~44)],[X~(44+1)],and give the combination rule of matissas. we find that for the equation X~n+Y~n=Z~n,there exist 660 combinations of the basic mantissa domains of most possible integer solution. According to the investigation on the mantissa domains of X~a,we introduce the practical equation for the combination of positive integers(it is also valid for negative integers).Then the indefinite equation X~n+Y~n =Z~n is substituted by the practical equation(C_z+101_n)~(?)+(C_(?)+101_(?))~(?)=(C_2+101_2)~(?). Thus,by using the combination rule of“mantissa domain”,Farmat's last theorem is proved. At the same time,|a~(n+1)-(b~(n+1)+c~(n+1)|>|a~n-(b~n+c~n)|>0 is proved.Thus,n>2,X~n+Y~n≠ Z~n is proved.

本文首先研究了 X~(n)尾数性质,从而得到了尾数域存在的4种类型为:[X~(4k-2)]·,[X~(4k-1)]·,[X~(4k)]·,[X~(4k+1)]·.并且得到尾数组合规律,发现满足方程:X~n+Y~n=Z~n 的最可能存在整数解的基本域尾数组合数组共有660组.通过 X~n 的尾数域研究,引出了正整数组合的具体方程(对于负数组合也同样成立),则不定方程 X~n+Y~n=Z~n 即由具体方程(C_(x)+10i_x)~n+(C_(y)+10i_y)~n+=(C_(x)+10i_(x))~n代替.因此,应用“尾数域”组合规律,证明“费尔马大定理”是成立的.同时证明|a(?)-(b(?)+c(?))|>|a~n-(b~n+c~n)|>0;以此证明 n>2,X~n+Y~n≠Z~n.

In our judgment, Mendel's paper in 1991 [4]remains the best theory on identification of non-minimum phase ARMA of non-Gaussian process. In this paper, we improve on Ref[4].We improve Mendel's mathematical model in the following way:Eq. (3)and Eq. (4) expressmathamatically Mendeli model. Eq. (5)and Eq. (6)are well known [2]. By substituting Eqs. (5)and (6)into Eq. (3),We obtain an improved mathematical model.We apply the improved model to studying identification of non-minimum phase ARMA process driven by an unobservable non-Gaussian i. i. d. process. We use 3-rd order cumulants andbispectrum of noise-containing output signals. The noise contained may be white Gaussinn orcolored Gaussian. By solving a set of linear equations, the parameters of MA parts and AR partsare estimated.Our method appears to be better in the fOllowing respects:(1) The structure of the proposed algorithm is flexible.(2) Noise effect can be much reduced.(3) The proposed algorithm does not need initial conditions.(4) The proposed algorithm is free of divergence problem.(5) In the case of non-causal ARMA parameters, our method can deal with all poles exceptthose lying on unit circle.

提出了一种新的ARMA模型参数辨识方法,该方法以受噪声污染的系统输出信号的三阶矩和双谱作为工具,通过求解一系列线性方程组,分别估计出ARMA模型的MA部分和AR部分的参数。其主要特点在于应用了基本域内的所有双谱采样,从而有效的利用了信息量。计算机模拟结果表明,它具有很好的数值特性和较好的参数估计。
