How much more reasonable is that opposing theory (it is not for that reason more true—) which Herbert Spencer, for example, espoused: that the concept "good" is essentially identical with the concept "useful,""practical," so that in the judgments "good" and "bad" mankind has summed up and sanctioned precisely its unforgotten and unforgettable experiences regarding what is useful-practical and what is harmful-practical.

这样一来那种反对派理论倒是更为清晰合理了（那理论并不因此而更正确——）。例如赫伯特·斯宾塞就表述了这派理论：他认为"好"的概念就其本质来说与"有益"、"实用"相通，因此在"好"和"坏"的判断中人类总结并确认的正是他们关于有益——实用和有害——不实用的那些未被遗忘和遗忘不掉的经验。

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.

为此，本文首先给出了前馈NN模型的&吸引子&和&吸引域&，&伪吸引子&和&伪吸引域&的定义，以及描述吸引域的指标，在此基础上提出了一种计算前馈NN模型&吸引域&大小的数学计算方法，该方法提出解决了目前依靠对检测样本的测试工作来检验NN容错性的繁琐工作，而用具理论意义的性能指标来检验，这是一个重要的突破；针对前馈NN容错性较低以致难于满足实用的缺点，根据NN实用稳定性理论，提出了一种提高其容错性的实用方法，建立了基于NN与模糊处理相结合的NN模型重构机制，重构NN&伪吸引子&和&伪吸引域&来大大地提高NN的容错性。
