First, well give some up to date results of research work about security for computer network, analyze what makes current computer network system to be unsecurity, and try to define a security computer network.

由于网络和分布式系统的出现，使用户能共享分布着的信息，用户之间可以通过通信信道交换信息，这对充分利用资源，提高系统性能无疑是十分有益的。

The whole simulation system was considered as a federation and distributed into several federates to carry out distributed simulation.

该方法利用 HLA 的模块化建模的思想，将整个仿真系统的功能划分成若干个联邦成员，进行分布式系统仿真。

The reason why Distributed System is chosen as the research environment is that most equipment used by telecommunication company are based on it, as it could afford large scale data computing.

因此，本文研究的切入点是如何在分布式系统中实现热补丁技术，使系统具有在线补丁维护功能。

On the background of mobile computing, distributed system, agent system and ontology, the author explores the mobile computing in limited environment at three levels, i.e., mobile computing formal model, mobile ontology and application model. Some targets of the research works include the dynamic ambients calculus, robust ambients calculus and mobile ontology. Some innovative contributions of the dissertation are enumerated as: 1、Proposing a mobile computing dynamic ambients calculus.
