DEVELOPMENT OF A PROTOTYPE SYSTEM FOR MULTI-OBJECT USE OF HYPER-INFORMATION IN WIDE AREA NETWORK

在为期三年的科学研究中，我们首先提出了广域网多目标超信息构建流程和超信息经济有效利用评价模型，以期在信息处理、科研机构间信息交换、科学展示、科学展示等方面提供一个多目标超信息利用的广域网原型。科学研究开发及研究成果对教材的修改。其次，构建了广域网中超信息多目标利用的原型系统，并尝试制作了一个超信息原型并对其进行了评估。第三，我们制作了广域网中多目标使用的物理教育、工程力学和教育技术超信息包，并评估了它们的可用性。最后制作了广域网超信息多目标利用原型系统，并对原型系统的实际有效性进行了评价。它由视频编码器和采用MPEG-1的视频服务器、www服务器和信息网络系统组成。

In the three-year-period scientific research we firstly made a procedure of constructing hyper-information for multi-object use in wide area network and a model of evaluating economic and effective use of hyper-information in order to make a prototype of wide area network for multi-object use of hyper-information available in the information processing, the exchange of information among research institutions, the scientific presentation, the scientific research and development and the modification of research products to teaching materials. And secondly we made a prototype system for multi-object use of hyper-information in wide area network and tried to make a prototype of hyper-information and assess it. We thirdly produced three packages of hyper-information on physics education, engineering mechanics and educational technology for multi-object use in wide erea network and assessed the availability of them.Lastly we made a prototype system for multi-object use of hyper-information in wide area network and evaluated practical and effective utility of the prototype system. It consists of the video-encoder and the video-server using MPEG-1, WWW-server and the information network system.
