These Lorenz systems are built, which are relevant and can be switched each other via the choicer. Chaotic synchronization of these systems is realized using same nonlinear feedback control method. The transmitter can be switched discretionarily among several chaotic systems, bring on ceaseless changing of the chaotic carriers in transport channel. In the receiver, the chaotic carriers are retrieved from the received signals, then the information signals are recovered.

Depending on this thought, and according to the relating principles of the science about system, we carried through the initial creating thought about innovation , which have already been discussed frequently by the experts. The innovative elements are the most radical factors in the innovative system, which are also the basal ingredients that creating the system. Complexity and uncertainty are the intrinsic characters of the factors, which endow the innovative activities with insignificance of unfolding; the mechanism of non-linearity makes these elements to produce all kinds of affiliations, subsequent the mechanism of conformity coordinates as well as colligates and blends and advances on the basis of non-linearity, thereby the innovative behaviors achieve the leap in the affects and functions, so the systematic affects and functions forms, the innovative behaviors construct the practical framework in the landscape and portrait orientation; in fact, the process of the systematism of innovation is human beings social behaving, so, the evolvement of the systematism of innovation possesses the essential natures of opening and arrangement as well as self-organizing and rushing, which are the principles of evolvement.

我们就是立足于这一思维方式，运用系统科学的有关原理，对近几十年来被学者专家频频讨论的词——创新系统进行了生成性的初步思考：创新要素是创新系统的最基本的因素，也是生成创新系统的基本因子，复杂性和不确定性是创新要素与生具有的内在秉性，而正是这些秉性的存在才赋予了创新活动以开展的现实意义；非线性机制使得各创新要素之间产生着千丝万缕的联系，整合机制又在非线性机制的基础上进行整理、综合、融会和提升，从而实现了创新行为在效应和功能上的飞跃，形成了创新的系统效应和功能，创新行为在时间和空间上建构着系统的实践结构；创新系统化毕竟是人类的社会实践行为，在创新系统化的过程中创新主体要积极地使其具有开放性、层次性、自组织性和涌现性，这也是创新系统化的运行理念。

The process features and shape features of the electronic part are classified and defined, and then the feature model library is built, which enables rapid input of the part information. The rules and methods of stamping process design are summarized to build the stamping process library, so that the stamping process can be designed rapidly and intelligently. Furtherly, the process design rules and methods in process station layout of multi-station progressive die as well as the methods of decompounding and compounding process and the expression method of the process station layout are concluded and summarized, and then the rule library and case library of process station layout are built. Designing the process station layout rapidly is carried out based on rules and cases. At last the rapid design function of process station layout is validated through simulating the rapid designing layout system of multi-station progressive die on Pro/E 3D platform.
