Chapter three (the methods of generating chaotic signal and its applications): In this chapter firstly the mechanism that a simple kinetic system, subsection linear map system, can generate chaotic phenomena is affirmed, the characteristics of correlation function of the chaotic signal generated by this system are simulated, on this basis a simple applicable method for generating chaotic signal is given; secondly some typical circuits generating chaotic signal are designed, also use operational amplifier to design a third -order autonomous circuit with chaotic dynamics. The basic mechanism and typical structures of chaos in the application of communication are introduced systematically and a simple method is provided for generating pseudo random code signal; At last Chaotic signal is applied into the analysis of system characteristic.

This paper analyses the PKI theory architecture detailedly, combining with researching the information security status quo and the wireless communication systems. On this condition, we put forward the feasible WPKI system, CA sub-system and RA sub-system logical frame diagram and network structure blue print. The technical criterions in the system and core content of WPKI, includes the certificate management(certificate requirement, certificate issue, certificate revocation, certificate query and so on), are discussed at length. In the end, the systems function and performance are tested.

An impulsive control scheme of the Lur'e system and several theorems on stability of impulsive control systems was presented, these theorems were then used to find the conditions under which the Lur'e system can be stabilized by using impulsive control with varying impulsive intervals. The parameters of Lur'e system and impulsive control law are given, a theory of impulsive synchronization of two Lur'e system is also presented.

From the planning of an economic public system to marketing economics that value individual benefits. From a directing society value system that values collectivism, national benefits and common goal to a multi-element society value system. All these have changed the directional collective actions, which also brought changes to its product the macro society element. Traditional solutions for collective actions are losing their effect, a new system is developing.

在本文中，由公有制下的计划经济进入个体利益明确的市场经济，由崇尚集体主义、国家利益和目标一致性关系的主导社会价值观进入多元价值体系，使得社会中的主导型集体行动类型发生转变，它所产生的宏观社会要素也随之发生改变，过去习惯了的解决集体行动的手段正在解体，新的制度手段正在形成。
