This dissertation shows each unstable asymptotic equilibrium point is just the pattern that refuses to be recognized by combining the idea about constraint and projection with the continuous network LSSM and the discrete network BSB, eliminates some shortcomings of LSSM and BSB in the distribution of attraction domain. LSSM and BSB are then improved to be ideal associative memory and can be implemented by circuit.

将约束投影思想与连续神经网络LSSM和离散神经网络BSB相结合，说明了不渐近稳定的平衡点恰是实际中拒识模式，根除了LSSM和BSB在吸引域分布等方面的一些缺点，将它们完善成为理想的联想记忆器，并且它可用电路实现。

A rain attenuation model based on artificial neural network is proposed to deal with the problem in this paper.

本文针对现有预测模型存在原理上的误差这一问题，将人工神经网络应用于雨衰减的预测中，建立了基于人工神经网络的雨衰减模型。

To date, most research on DTCNNs has restricted to the stability of a system[17-19,37,38].Few papers consider the existence and attractability of periodic so-lutions.

迄今为止，大多数文献局限于研究离散细胞神经网络模型的稳定性，很少考虑离散时间细胞神经网络周期解的存在性及吸引性问题。

In this thesis, we describe some important properties of the dynamic behaviors of several class of time-discrete models of two neurons, which includes stability, asymptotic stability, the existence and attractability of periodic solutions, Flip-bifurcation and Neimark-Sacker-bifurcation.

本学位论文对几类二元离散神经网络模型的动力学性态进行了定性分析，讨论了这些神经网络模型的稳定性、渐近稳定性、周期解的存在吸引性、Flip-分岔和Neimark-Sacker-分岔，全文共分五章。

In comparison, the 20-year-old after the beginning of the use of mobile phones of people suffering from glioma risk increased by 50%, suffering from auditory nerve tumors to increase the risk of 1 times.

相对而言，20多岁以后开始使用手机的人患神经胶质瘤风险提高50％，患听觉神经瘤的风险提高1倍。

Baxter, working on cats under experimental conditions comparable to ours, however, reported that intravenous injection of adrenalin either had no marked effect or a slightly augmentative effect on the histamine-induced secretion, and that stimulation of the splanchnic nerve yielded similar results.

若用较长的间隔如每10—30分钟收集一次胃分泌，则此双相效应就会被掩盖，因而得出肾上腺素对猫胃分泌无明显效应或有增加分泌的效应的结论，如Baxter等人所得到的一样。在急性实验中，刺激大内脏神经对组织胺引起的猫胃分泌有显著的抑制效应。与肾上腺素的效应不同，刺激大内脏神经的效应通常是单相的。

An augmented matrix is therefore given, of which the number of dimensions is determined by adding the observed data for l time past together, and the forecast data after augmentation are taken as the input variables in BP neural network. Then, a forecasting model is developed on the basis of DPCA-BP neural network, with its architecture described.

通过计算前l时刻数据确定增广矩阵的维数，并把得到增广后的预测数据作为BP神经网络的输入变量，建立了基于DPCA-BP神经网络的预测模型，给出了模型结构。

目前临床上还是用自体神经移植作为桥接神经缺损的方法。

The split between the two groups can hardly be papered over.
