Power control is one of the necessary key techniques for mobile communication systems. The frame structure of WCDMA communication system is different from those CDMA commination systems, which have only one type of traffics. In addition, multimedia services have different quality of service requirements. Thus the power control for WCDMA communication system will different from that in narrow band CDMA communication systems.

功率控制是CDMA移动通信系统中必不可少的关键技术之一，WCDMA移动通信系统的结构不同于单一业务的CDMA移动通信系统，且多媒体业务有不同的服务质量要求，因此，WCDMA多媒体移动通信系统中的功率控制将不同于单一业务的CDMA移动通信系统中的功率控制。

The basic concept and characteristics of missile system-of systems combat simulation for effectiveness evaluation were summarized and the problems of simulation model specification were analyzed, then the hierarchical description and composition method based on system-of-systems, entity and behavior was proposed as the modeling methodology of system-of-systems combat simulation, which is SEB composable modeling methodology. Then, the reference model of SEB methodology and the modeling reference view of various hierarchies were discussed.

总结了面向效能评估的导弹体系对对仿真基本概念和特点，分析了体系对抗仿真模型描述中存在的主要问题，在此基础上，提出体系－实体－行为的分层组合描述方法，作为体系对抗仿真的建模方法，即SEB组合建模方法，并给出其参考模型和各个层次建模的参考视圈。

In its developmental history, software systems are categorized as either algorithmically computable systems or interactive computing systems.

从计算机软件系统的发展历程来看，主要可分为算法可计算的软件系统和交互式计算的软件系统两个阶段。

The controller makes the closed-loop systems internally stable and minimizes the H2 norm of the transfer matrix Tzw from w to z. Two Riccati formulae based on 8 operator is deduced. The H2 problems for continuous time systems, Z operator models and 8 operator models are investigated respectively.The guaranteed cost control problem of robust stabilization and robust performance for uncertain systems which is described by 8 operator is discussed in this paper.

Based on the wide concerns about the Integrated Social Emergency Response Communications Systems,this paper mainly discusses the development strategies for digital trunking and emergency communications in China. The establishment of the state /province/city level integrated emergency response communications systems is very important. The plan and implementation of new generation Integrated Emergency Response Systems following the concepts of NGN and 3G evolution should be taken into consideration, The relationship between public networks and IERS should be correctively dealt with and actively coordinated. Besides, it is involved how to accelerate technology innovation, open correlative standards and interfaces, and promote effective interconnection and interoperation for operators and users to gain maximum benefits.

文章在论述目前广为关注的社会应急联动通信系统的基础上，探讨了中国数字集群及应急通信的相关发展策略，如有关国家/省/城市级应急联动通信的重要性，如何基于NGN及3G演进概念规划与建设新一代应急联动通信系统，如何正确处理与有机协调公众网络与专网应急联动通信之间的关系，如何加速技术创新，如何开放相关标准与接口、促进有效互联互通、维持多厂商环境下运营商及用户利益最大化等。

In history and reality, the contradiction between needs and limited resource always exists. From the view point of system-science, it can be concluded that:①The interaction among need-contradiction-ability is the perpetual force for enterprise evolution (and the evolution of other living systems). The improvement of "ability"is the process and result of evolution.②The competition and coordination among systems is the direct power for enterprise evolution. Competition produces various system actions. Coordination makes systems complement their functions with each other. The interactions of competition and coordination push enterprise into the flow of evolution and optimization.③The"stochastic fluctuation"of the system, which is accidental finding, is another force for enterprise evolution. It is a deterministic element in the process of the self-organization of enterprise.

在历史和现实中，需要和满足需要资源稀缺之间的"问题"是恒久存在的，从系统科学的角度可以演绎出：①需要一问题一能力三种异质要素的相互作用是企业进化（其它一切有生命系统进化）的永恒动力，"能力"的提高正是进化的过程和结果；②各系统间的竞争与协同是企业进化的直接动力，竞争产生多样化的系统行为，协同则使各系统间优势互补，竞争与协同交互作用推动企业呈现出进化与优化的趋势：③系统的"随机涨落力"即意料之外的发现与创新是推动企业进化的又一种动力，它是企业自组织过程中带有必然性的力量：④在解决"问题"中创新者的作用不可低估，但更为根本地说创新者只是"需要一问题一能力"这三种要素相互作用的载体，个体的创新是企业自组织过程的必然结果。
