By analyzing the distribution of the zeros to the transcendental characteristic equation associated with the trivial.solution,we obtain some- sufficient conditions on the stability and instability of the trivial solution.These results are generalized to n-unit neural networks by means of space decomposition in this Chapter.

在第二章中，我们讨论了不带自反馈与带自反馈的3元环状神经网络系统平凡解所对应超越特征方程的根的分布情况，确定了系统平凡解稳定与不稳定的充分条件，并利用空间分解的方法把相应的结果推广到n元环状神经网络系统。

Due to N-N bond weakest, nitrosamines are denitrosated by HBr/HOAc to release nitrogen oxide, which can be oxidized to form NO〓. Trapped in sulphanilamide and N-1naphthylethylene diamine di-HCl solution, the NO〓 transforms into NO〓 and develops color in the solution.

该法根据亚硝基官能团中N-NO键的键能最低，采用氢溴酸/醋酸溶液选择性断裂N-N键，对逸出的NO通过氧化成为NO〓然后用显色剂吸收，再由分光光度计测量吸光度并计算出亚硝胺含量。

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.

然后利用聚丙烯酸与EOPO之团聚共聚合物，添加双官能基粉体及液晶E7，制备成液晶溶液再注入液晶盒里，放置光罩并给予固定外加5V电压在UV下进行曝光，然后在偏光显微镜下外加电压观察液晶盒的平面显示变化现象，发现四号高分子的液晶溶液在3%时，可以明显观察未被光罩遮蔽的高分子将会聚合形成高分子格子结构，并造成液晶成高倾角排列，顺著光罩形成不连续的结构藉以影响墙周围的液晶，从光电量测结果显示，利用此种不连续结构不仅可将内部液晶结构维持在twist的状态，也成功提升OCB原有的响应速度。

The results show that:(1) MnO2 deposition on the surface is the main factor resulting in cathode polarization, and the flowing of the solution can remarkably reduce this polarization. Furthermore, the buffered solution can reduce the polarization resulting from H+ concentration difference;(2) it is deduced from the polarization curve that the key factor influencing the performance of MFC is microbial number and metabolic rate and the electron transferring rate from microbial to electrode;(3) the power density arrives at the biggest, 824 mW/m2, when outer resistance is 300 Ω, which is accordance to the inner resistance,(284±18)Ω, deduced from I-V curve;(4) the influences of pH and permanganate concentration on cathode potential is in agreement to Nernst equation.
