Constructing a prediction mode to predict a future running state of complex mechanical equipment by using Lyapunov exponents is based on uncontrived and intrinsic chaotic characteristic of the monitoring time series. Thus contrived impress ingredient included in other prediction methods is avoided. This is a try to express running current of a monitoring facility by its chaos phenomenon.

采用Lyapunov指数构造预测模式进行复杂机械运动状态的预测，是基于监测数据的时间序列客观存在的内在混沌特性进行的，避免了以往预测方法中主观确定因素的影响，这是一种运用被监测体客观混沌现象描述其变形规律的尝试。

The security of several typical chaotic synchronized secure communication schemes , as well as the respective unmasking methods are studied to find the way to improve the security. A new secure communication scheme based on active-passive decomposition using parameters perturbation technique, which makes it has a kind of dynamic secrete key, is analyzed in this paper.

"I have you both beaten," the lawyer gloated."Before Adam and Eve, before the Garden of Eden, before all creation, there was a state of chaos, and who do you think could have created that?"

&你们俩的都不如我的早，&律师得意地说：&在亚当和夏娃之前，在伊甸园之前，在所有这些创造之前，有个混沌的世界，你们知道，是谁制造了那个混沌的世界吗？&

Furthermore, the method is not always an optimized one and big oscillations and overshoots often occur to the control system.

引言混沌是在非线性系统中普遍存在的现象，混沌运动具有对初值的高度敏感性、运动轨迹的遍历性和随机性等特点。

Modeling and prognosticating of time series in economics have became a hot spot in now days .

同时随着混沌理论和应用技术研究的不断深入，经济混沌时间序列的建模和预测已成为近几年来的一个重要研究热点。

ABSTRACT Erbium-doped fiber laser has attracted much more attentions for its greatly potential application. It upbuilds good theory and experimental foundation for the application of erbium-doped fiber lasers in optic communication, optic detection etc. to study control and synchronization of chaotic erbium-doped fiber lasers.
