【摘要】 工科实验教育的显著特征是将实践知识与理论知识有机联系在一起，并借助于一定的实验手段来培养学生的技术应用能力和工程观念。完善的实验手段和实验管理方法将使实验教育更富成效。 随着网络的全球化以及计算机技术的进步，建立完备的实验管理手段已成为可能。本论文以分布式体系结构、面向对象技术、设计模式、基于组件的软件开发等理论为基础，着重阐述了在网络环境下创建机械工程类课程的实验教学环境——分布式设计实验平台的实现技术。本实验平台包括C/S模式下的客户端软件和基于Web的实验信息管理系统两个部分：前者采用组件化的方法实现了应用工具软件的集成，并通过图形文件信息的自动提取算法和同步存储算法建立了实验平台与应用工具软件之间的通讯接口。客户端软件还提供了基于SMTP的邮件工具以支持协同设计工作。客户端软件主要承担实验操作和管理等任务。后者则实现了基本的实验信息查询、注册、浏览等功能，它采用B/S体系结构，使用COM+技术对用户的数据访问进行了逻辑上的控制。 分布式实验平台集工程设计、有限元分析、实验数据管理、信息查询等功能为一体，既具备实验教学价值，又具有一定的工程应用潜力，并为后继的开发打下了一定的基础。更多还原

【Abstract】 Combining theory with practical knowledge and recurring to special method to foster student’s project conception and ability of practicing technical knowledge has become one of the greatest characteristic in mechanic engineering education. Perfect experimental administrant means comes with effective experiment education.With the Network globalization and the progress in computer technology, it is possible to establish self-contained experimental, administrant means. Based on the theories of distributed software architecture, objected-oriented and component-based, this paper focuses on the implementation technology of distributed design experiment platform, which serves as a experiment-teaching environment in mechanic engineering course. The experiment platform has two parts: client software system under C/S pattern and experiment information system based on Web. The former tend to solve the problems of application software integration and develops some communication interfaces between platform and application software that are described in file information automatic distilling algorithm and synchronous storage algorithm. The client software strongly supports cooperative design in experimental experiment with the help of SMTP mail tool as well. The latter system has some important function: information query, registration, browser etc. The experiment manage information system builds a mechanism constructed by COM+ to realize user data access control under B/S pattern.Distributed design experiment platform can meet the need of engineering design, FEM analysis, experimental data management and information query. The platform provides valuable applied foreground in experiment-teaching field and engineering fields. Meanwhile, it makes a foundation for further research.更多还原
