摘　　要：框架是软件复用研究中的重要课题之一,但是框架在不同的领域中有不同的特性,需要将框架的特性与共性分离,将共性部分单独加以实现并复用,使得研究人员的注意力集中在各个领域的特性部分.本文提出并研发了一个基于构件和双总线的分层微内核结构的基础设施—FreeScaler.该基础设施属于框架共性的实现,具有高度的开放性和灵活性,为科研试验和应用开发提供了一个快捷易用的平台.文中重点介绍了FreeScaler的设计思路、整个系统的模型和体系结构,阐释其关键特性,并展示了基于FreeScaler的实际应用.Framework is the important subject of software reuse research, while the framework bears the speciality in the different domains, to separate the generality from the speciality is needed. For the generality＇s separate implementation, its reuse, and focusing on the different parts of each domain of interest when researchers are working, a component-based and dual busbased multi-tier infrastructure-FreeSealer, with micro kernel structure built in, has been developed. The FreeSealer infrastructure, as a platform for scientific research and application development, is the realization of the common parts of the different frameworks with the characteristics of high-level openness and flexibility. This paper focuses on introducing its design thoughts and the model and architecture of the whole system, describing its key characteristics and demonstrating the real world applications, which are based on the FreeSealer.
