在对当今主要普适计算研究项目，尤其是面向普适计算的软件集成环境原型系统进行介绍的基础上，本文对面向普适计算的软件集成环境所关注的共性问题进行了归纳分析，包括如何为应用提供自适应的软件体系结构支持、如何为应用提供普适计算环境下所需的可重用服务、如何根据普适计算环境的特点对传统中间件技术的内涵进行扩展等等，并对面向普适计算的应用需求下软件集成环境研究所面临的挑战进行了讨论。

Based on the introduction of the wellknown pervasive computing research projects, especially the implementation of those pervasive computingoriented software integrated environment prototypes. this paper sums up and analyzes some common problems that the  research of pervasive computingoriented software integrated environments focuses on, including the support of the selfadaptive software architecture, the reusable services and the extensions to the traditional middleware techniques to adapt the pervasive computing environments. Subsequently, the challenges of the research on software integrated environments in the pervasive computingoriented applications are also  discussed.
