Construction of an Instruction System for the Strength of Materials by using Multimedia and Inter-Net.

为了构建教材强度教育的计算机辅助教学系统，我们做了以下几个方面的工作。利用电子书构建计算机辅助教学系统。我们制造了混血儿。它包含了许多电影、有声动画和实践。这些电子书被许多调查人员拿来检查。WWW服务器系统的构建将电子图书中的内容转换为WWW页面。为了使教学系统具有更强的交互性，制作了两种虚拟机，即虚拟拉力试验机和虚拟悬臂。提出了基于internet的低成本远程授课系统的构建与实践分析。该系统与清单2中的WWW服务器系统在实际的强度材料讲座中使用了两年4。将材料强度的讲座录制到VOD系统中。将一学期的授课材料强度记录为VOD视频数据。一些讲座是用视频点播系统做的。将多媒体资料的强度向公众展示多媒体资料已向公众展示。所有数据保存在两张CD中，这些CD将由许多调查人员发送和调查。许多人建议我们，虚拟现实无法忍受现实世界。通过研究，我们得出结论，不仅需要计算机模拟，还需要实际的实验和分析。在接下来的研究中，我们应该做一个CAl系统，它很好地包含了这三个目标。

In order to construct the Computer Aided Instruction system for the education on the strength of materials, we have done the follows.1. The construction of Computer Aided Instruction system by using the Electric Book.We made the hybrid. It contents many movies, animations with sound, and practices. These electric books were derived to many investigators and inspected.2. The construction of WWW server systemThe contents in the electric book were converted to www pages. In order to make more interactive instruction system, the two kinds of virtual machines were made, (1) the virtual pulling test machine and (2) the virtual cantilever.3. The construction of remote lecture system and practical analysisThe remote lecture system with low cost by using inter-net were made. This system and the WWW server system in the list 2 were used in the actual lecture of the strength of materials for two years4. Recording the lecture of the strength of materials into VOD system.The lecture of the strength of the materials over one semester is recorded as VOD video data. Some lectures were made by using the VOD system.5. Present the multimedia information of the strength of the material for publicThe multimedia data has been presented to public use. All data were saved into two CD-ROM, and these CD will be sent and investigated by many investigators.Many people suggested us that the virtual reality could not stand the real world. Through this study, we conclude that the not only a computer simulation, but also real experiments and analysis should be need. The following study, we should make the CAl system, which contents these three objects in good valance.
