As a result, for feed-forward NN model this paper first proposes the concepts of"attractor"and"attraction region","fake attractor"and"fake attraction region", and norm of describing"attraction region". Further this paper presents a mathematics method of calculating feed-forward NN"attraction region", it solves the overelaborate job of checking NN fault-tolerance performance by testing all detecting samples, so to test fault-tolerance performance using theoretic characteristic norm is an important break. In accordance with feed-forward NN low fault-tolerance and difficult to satisfy practical application, according to practical application theory, this paper presents an actual method of enhancing NN fault-tolerance performance, builds the mechanism of reconstructing NN model based on combining NN and fuzzy process, reforms NN "fake attractor"and"fake attraction region"to enhance NN fault-tolerance performance greatly.

In this chapter, three kinds of target recognition methods are performed, which are:①Target recognition method based on the description of polarization parameter plane. The echo polarization states of target are projected onto the polarization state plane described by the ellipticity ε and the tilt angle τ of the polarization ellipse, the change of parameter following ferquency becomes the chart. According to the changing trait of the chart, the multidimensional polarization feature space of target has been contructed. Furthermore, a series of polarization feature parameters used in designing the structure of target recognition device are extracted, and they are insensible to the posture of target.②Target recognition method based on the description of Poincare polarization sphere. The echo polarization states of target expressed by Stokes vector are projected onto the Poincare polarization sphere. The conception of polarization ferquency stability, which is used in describing the dynamic distribution characteristics of the target echo polarization states on Poincare polarization sphere, has been defined. A group of polarization feature parameters used in designing the structure of target recognition device are extracted, and they are insensible to the posture of target.③Target recognition method based on the description of frequency sensitivity. In accordance with the conception of the polarization state distance defined on Poincare polarization sphere, the frequency sensibility of the physical structure property of target has been investigated, the frequency distribution feature curves in PSD domain are obtained, and targets'features are extracted by means of the curve-fitting method with Least Square Criterion.

这章具体研究了基于三种极化散射特性描述的相应的目标识别方法：①基于极化参数平面描述的目标识别方法，将目标回波极化状态投影到以极化椭圆参数，即椭圆率角ε和倾角τ表征的极化状态平面上，参数随观测频率的变化就形成了图，根据图的变化特点构造了目标的多维极化特征空间，并提取了不敏感目标姿态变化的极化特征参数组来设计目标的识别器结构；②基于Poincare极化球面描述的目标识别方法，采用Stokes矢量表征目标回波的极化状态，并将其投影到描述极化状态的Poincare极化球面上，定义了极化频率稳定度的概念用以刻画目标回波极化状态在Poincare极化球面上的动态分布信息，提取了准方位不变性的目标极化特征，最后设计了目标的识别器结构；③基于频率敏感性描述的目标识别方法，通过在Poincare极化球面上所定义的极化状态距离的概念，研究的是复杂目标物理结构特性对探测信号频率的敏感程度问题，获得了在极化状态距离下的频率分布特性曲线，采用最小二乘估计曲线拟合方法，它既用于极化特征的降维，同时又直接将拟合参数作为目标的分类特征。

Therefore has carried on the next experiment: For the proof slip of paper dry scope migration is but because of receives the earth's attraction the influence to concentrate toward the slip of paper lower part, we have carried on the next experiment, we cut the slip of paper the long strip, then changes the level laying aside, because whether there is can't such slip of paper both sides underneath the space cause the hydro energy downward to concentrate create the experimental result the difference, after the experiment discovered, after has removed this difference, the slip of paper both sides dry need the time is nearly same, but according to above experiment, we arrived following conclusion, the slip of paper dry scope is downward moved from on downward migration because of the slip of paper in moisture content by the attraction attraction, causes under the slip of paperAbove the hydraulic modulus also must be many, above the natural slip of paper falls very quickly on the few water on the evaporation, but under many moisture content need more time can evaporate, causes the slip of paper dry scope most above downward to increase slowly from the slip of paper.

急！！！物理翻译中翻英请帮帮忙於是进行了下一个实验：为了证明纸片〈paper sheet〉乾燥范围的移动〈boundary of drying〉是因为受到地心引力的影响而往纸片下部集中，我们又进行了下一个实验，我们把纸片剪成长条状，然后改为水平放置，这样纸片两端就不会因下方有无空间使水能往下集中而造成实验结果的差异，实验后发现，去除了这个差异后，纸片两端乾燥所需的时间几乎相同，根据以上的实验，我们的到了以下的结论，纸片乾燥范围从上往下移动是因为纸片中的水分被引力吸引而往下移动，使得纸片下面的水比上面还要多，自然纸片上面就少量的水很快就蒸发掉，而下面较多的水分需要更多的时间才能蒸发完，使得纸片乾燥的范围从纸片最上面慢慢往下增加。

Three factors (the total rate of win, the difficulty and the benefits execratory of winning a big prize) which influence the attraction to buyers are considered, and attraction function to evaluate the scheme's rationality is structured using classification weighting method. 3 Buyers'psychological curve is introduced and a model to describe the attraction of a scheme to buyers is built.
