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

为了构建教材教育计算机辅助教学系统，我们做了以下工作： 1．利用电子书构建计算机辅助教学系统。我们制作了混合体。它包含许多电影、有声动画和练习。这些电子书经过多位调查人员的导出和检查。 2． WWW服务器系统的构建将电子书中的内容转换为www页面。为了使教学系统更具交互性，制作了两种虚拟机：（1）虚拟拉力试验机和（2）虚拟悬臂。 3．远程授课系统的构建及实用分析利用互联网制作了低成本的远程授课系统。该系统和列表2中的WWW服务器系统在材料强度的实际讲座中使用了两年4。将教材强项讲座录入点播系统。将一学期的教材强项讲座录制为点播视频数据。部分讲座采用视频点播系统进行。 5．向公众呈现素材强度的多媒体信息多媒体数据已呈现给公众使用。所有数据都保存在两张CD-ROM中，这些CD将由许多调查人员发送和调查。许多人向我们建议，虚拟现实无法忍受现实世界。通过本研究，我们得出的结论是，不仅需要计算机模拟，还需要真实的实验和分析。在接下来的研究中，我们应该建立一个很好地满足这三个目标的CAl系统。

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.
