With the continuous development of computer science and technology, the application systems in the future will be multilayer ones based on the object oriented, distributed, isomerous conditions. This kind of system is composed of distributed objects one by one, which have given functions singly. These objects are independent of network protocols, programming languages, and software and hardware platforms. These pro- perties make them communicate each other and work corporately.

随着计算机科学技术的不断发展，未来的应用系统将主要是建立在面向对象的、分布的、异构的、自治的环境中的多层应用系统，系统主要由一个个分布式对象组成，对象各自具有特定的功能，可以跨越平台，独立于网络协议、编程语言和软硬件平台，实现相互通信，协同工作。

Results The behavioral features of the aged learning and memory impaired rats were as follow: 1 There was little change happened to the sample performance. 2 The spatial reference memory had obviously declined. The swimming times of searching the hidden platform in the place discrimination performance, the swimming time in a 40cm annulus at the primary platform place (A40T) and the platform crossings in the probe trial performance were the most suitable indexes for mirroring the spatial reference memory abilities. 3 The spatial working memory had not decreased so clearly.

Several experimental applications have been developed finally. In this paper, there areinnovations from the following four aspects:1. Definition and research methods of current distributed system and distributedinteractive simulation system follow those of traditional parallel computing system.While this paper points out it is one-sided to measure the scalability just from thenumber of processors and performance of a system, because the resources of distributed systems are heterogeneous and they can be used in diverse applications. Inthis paper, scalability of distributed interactive simulation platform is defined as theability of scaling (including scale-up and scale-down) in functionality and performanceof systems which is run on the platform when number of processors and otherhardware resources such as network change, i.e. when problem size is scaled up and system resources is increased, the performanceremains fixed and it is easy to expand the functions of simulationapplications.

本文的创新工作主要体现在下述4个方面：1、现有的分布式系统和分布式交互仿真系统可扩性的定义和研究方法都沿用了传统的并行计算系统可扩性的定义和研究方法，本文指出分布式系统的系统资源异构多样、应用种类丰富多样，只从传统方法采用的处理机资源和性能角度衡量一个系统是否可扩是有一定的片面性，提出了分布式交互仿真平台可扩性的定义是在处理机和网络等系统资源变化时，运行在平台上的分布式交互仿真系统在性能和功能方面发生扩缩的能力，即当问题规模扩大时，增加系统资源，系统能获得指定的性能及在功能方面能方便进行扩充。
