Research indicates that technique curriculum implemented on school level shows such characters:(1) For the subject reception, students, Teachers, schoolmasters and teaching researchers all agree on the importance of technique curriculum, but Students and Teachers have lower degree on the subject reception of the curriculum text. As the curriculum value recognized by Student and Teachers, general technique is"enhance the applicatory ability","sense the technique during the daily life", information technique is"inspire the innovation","cultivate information management and exchange ability"; Teachers and teaching researchers oppugn the curriculum aim orientation on information literature; Students and Schoolmasters'understanding on the general technique curriculum doesn't agree with their action.

研究发现，学校实施的技术课程表现出如下特征：第一，主体认同方面，学生、教师、校长和教研员一致认同课程的必要性，但学生和教师对课程文本的总体认同感偏低；学生和教师最认可的课程价值，通用技术是&提高动手能力&、&感知生活中的技术&，信息技术是&激发创造性&、&培养信息处理与交流能力&；教师和教研员对信息素养的课程目标定位存在质疑；学生和校长对通用技术课程存在认识与行为相悖的状况。

GIS as a new-fashioned information system provided of powerful functions and comprehensive applicability, the technique of 3D visualization must be imported in order to make GIS carrying on well and satisfying the users.

三维可视化技术是目前计算机技术和信息技术发展的一个热门研究方向，而且它符合人获取外界信息的生理因素，即首先通过视觉效果来对信息进行直观获取。

Such rebuilding is the precondition of setting up new self-learning modes. And then, to reach the goal of efficiently self-learning in network environment, we have to: break through the traditional way of education, in such way students are just being indoctrinated with knowledge and skills; integrate information technology course with other disciplines, improve the status of information technology in the culture education, and this also can help to enhance the students" quality of information technology skills; fully utilize the internet resources but under teacher"s instructions.

第四章通过分析与总结，得出了本研究的结论：在网络环境下，重新定位教师和学生之间的关系，突出学生的主体作用，构建新型教学模式是自主学习的前提；破除传统信息技术教学单纯知识和技术教学的模式，加强信息技术课程同其他学科的整合，提升信息技术教育文化内涵是提升学生信息素养的重要方法；在教师引导下，最大限度地利用互联网的资源是实现学生自主学习的有效途径。

For this, on the foundation of narrating the contents, characteristics of teachers modern in...

Firstly, This text has described information fusion technology characteristic, form structure and concrete processing method, and application of information fusion in fault diagnosis proves the feasibility and validity from the angle of information theory. Based on this,it is combined the fault diagnosis of aeroengine with Information fusion, a method and model which the fault diagnosis of aeroengine information fusion is brought forward. a research which combined neural networks with D-S evidence is brought forward. Based on the analysis of single neural network characteristic, the model of roted neural network is put forward. With the simulation based on the example, we can know evidence theory fusion improved the fault diagnosis It is hard to give the basic probability function in the process of using the evidence theory, So the model based on network and D-S evidence is put forword.
