摘要：An internet-based information and monitoring platform for the specific requirements of geotechnical engineering projects is presented. The platform is based on a hybrid-model approach consisting of a model-based information management system and a resource management system, the latter also referred to as DCMS. Project key information can be accessed via the main user interface, the 'graphical navigator'. The graphical navigator provides also a direct access to additional information in the DCMS. Prompt reac-tion in exceptional situations as well as in daily work gets an extensive support. In practical applications it has been proven that this platform seems to be an adequate tool especially for risk assessment and management in geotechnical engineering projects. Components and advantages of the platform as well as ex periences from the applications are presented and discussed in the paper.

摘要：设计了基于internet的支持体育教学与科研活动的综合性网络环境。采用文献分析和系统分析的方法,面向体育教学与科研的特点,遵循国内外教育技术的相关标准,提出了具有网络教学、网络科研、教学资源库和专业数据库相结合的平台化网络支撑环境的总体结构。对该环境的3个主要部分:网络教学平台、学术研究平台和体育专业数据库进行了功能设计。其中网络教学平台包括网络课程、答疑讨论、课程作业和在线测试等主要模块,学术研究平台包括信息共享、学术交流和协同研究等主要模块。下一步的研究将对上述系统进行软件实现,并对该系统的应用效果作实证分析并据此对该设计方案进行有效性验证。

摘要：笔者总结了在internet上进行多模式、多策略地采掘和获取知识的途径、方法,提出了在internet上进行知识处理的3个层次,即基础层(查询、浏览和检索);中间层(综合、集成、设计、归纳和模拟等,或称为开发研究层);高层次(创意、创作、构思、辅助决策等,或称为应用研究层).这个思路,笔者认为是在internet上进行研究与开发的必然趋势,且该课题组已做出了几个针对具体领域的实验系统.实践证明这个思路是可行的,已受到用户的欢迎.
