This thesis is composed of two chapters . the first chapter deals with one kind of two - neuron neural networks with positive self - feedback coefficient . in chapter 2 , we discuss the simular system with negative self - feedback coefficient 本文分两章，第一章讨论自反馈系数均为正的双阈值的二元神经网络模型( ) ，第二章讨论自反馈系数均为负的双阈值二元神经网络模型( ) 。

The result manifests in the pearson " s correlation coefficients : e dimension has significant positive but low correlation with mature and neurotic defense factors ; n dimension has significant positive correlation from medium level and decreased progressively with immature neurotic and mature defense factors ; p dimension has simular phenomenon as n dimension while l dimension has negative and medium level of negative correlation with pretence factor 在dsq与epq的相关结果表明： e维度与成熟型和中间型防御因子有低的正相关； n维度与不成熟、中间型和成熟型相关从中等依次递减； p维度的情况与n维度相若； l维度与掩饰因子中等程度的负相关。
