First, the Lyapunov functional and variation of constants method are adopted to study the effect that Sigmoid function and the relation of resistance, capacitance and current in Hopfield neural networks have on the stability of networks. The stability criterion constructed by physics parameters is obtained. Thus how the constrained relation of physics parameters affects the stability of Hopfielf neural networks is clear. Based on the study above, the perturbation model of recurrent neural networks is constructed. And the theorems of the existence of solution of perturbation model are presented.

首先，采用Lyapunov泛函法和常数变易法研究Hopfield神经网络中给出的电阻、电容、电流之间的关系以及Sigmoid函数对网络稳定性的影响规律，得出仅由物理模型参数构成的稳定性判据，从而弄清物理模型参数约束关系对Hopfield神经网络稳定性所起的作用，在此基础上，构建了递归神经网络的扰动模型，并通过讨论扰动模型解的存在性问题，给出递归神经网络扰动模型解的存在性定理。

Means to set up a physics model and requests for abstraction, association, supposition , analogism, and so on in the process of setting up the model flexibly and vividly to meet and put forward in the light of the importance of physics model, which can partly promote the development of the thinking science and have important realistic meaning to the teaching research.

What I did is very straining at the beginning, often baffled by the question which the classmates put forward, For letting this piece with right titles and proper words I, I begin under lesson time study physics, The content that previews on one ' s own initiative followingly, dabble some knowledge after class, gradually, I can be calm in the face of various kinds of which everybody put forward at last Question, it wins physics of Beijing the first prizes of contest even the achievement unable term describe by speech sense, I have overcome the joke which is opened by the destiny with my own effortat last.

一开始我做的很吃力，常常被同学们提出的问题难倒，为了让我这个物理课代表能够当的名正言顺，我开始在课下时间研究物理，主动预习后面的内容，涉猎一些课外的知识，渐渐的，我终于能够从容的面对大家提出的各种问题了，甚至还获得了北京市物理竞赛的一等奖，那种成就感简直无法用语言形容，我终于用我自己的努力战胜了命运和我开的这个玩笑。
