Because the time series generated from finite difference equation with chaos may also possess exponential distribution of probability density. Additionally, irregular dynamics has ever been attributed to the presence of stochastic noise in many systems, but actually it may result from chaotic process in deterministic system.

近年来对非线性动力系统的深入研究发现：观察到某一过程具有指数型概率密度事件分布并不足以确定它就是泊松过程，由具有混沌行为的有限差分方程所产生的时间序列也可具有指数型概率密度分布；在许多系统中，过去归因于随机噪声的不规则动力学特性，实际上很有可能是由确定性系统中的混沌过程所致。

The existence,uniqueness and globally exponential stability of the equilibrium point of a dynamic neural network with distributed delay s were studied without assumption of boundedness and differentiability of activation functions.

在没有假定激励函数有界、可微的情况下，研究包含分布时滞的动态神经网络平衡点的存在性、唯一性和全局指数稳定性。
