On this basis , we explore the practices of context - creating in demonstrating experiment of university physics , in the experiments of high school physics teaching methods and in the university physics under the environment of campus network separately 在此基础上，分别对大学物理演示实验、中教法实验和校园网环境下大学物理学的情境创设实践进行了探索。
To overcome these difficulties , it is necessary to design systematically the process of lecture experimental teaching according to the three dimensionalities , that is , the " conflation and degree " of cognition , the route of cognition , and the method of cognition 要克服这些困难，有必要从认识的“内涵及程度” ，认识的路径以及认识的方法三个维度对演示实验教学过程进行系统化设计。
We make a vital model of cellular automata based on two - dimension . we make tests with this model and get some significant results . this simulating program proves cellular automata can simulate phenomena of life and life - like behavior 我们首先建立了一个具有生命规则的二维细胞自动机模型并作了模拟演示实验，这个仿真程序说明细胞自动机可在计算机上模拟生命现象或类似于生命的行为。
Finally , a near real - time software - only demo is presented to demonstrate the overall procedure from video acquirement , video coding , transmission , to video decoding and playing , which confirm the practicability and efficiency of above techeniques 综合以上研究，实现了一个局域网内视频传输演示实验系统，该系统包括采集、压缩编码、传输、解码和显示等环节，从而验证了研究成果的实用性和有效性。
Experimental demonstration of the physical basis of imparting knowledge , training students in the spirit of intensive study , and guide students to observe , to think , to the establishment of physical thinking , learning physics is the scientific method very important role 演示实验对传授物理基础知识、培养学生的钻研精神，引导学生观察、思考、建立物理思想、掌握学习物理的科学方法都有很重要的作用。
The absence of students ' perceptual knowledge , the chasm between perceptual cognition and rational cognition , and the lack of dimensionalities in the " three - dimensional teaching target " are the common difficulties of physical lecture experimental teaching in middle school 摘要学生感性认识的缺乏、感性认识与理性认识脱节以及“三维教学目标”中维度的缺失，是中学物理演示实验教学面临的带有共性的困难。
This paper mainly discuss 3 strategies of it : give prominence to characteristic of demonstrating experiment , inspire studnes " emotion ; build nicer demonstrating experiment room of university physics ; optimize demonstrating experimental context by using multimedia 本文主要探讨了情境创设的三个策略：突出演示实验的特点，激发学生的情感；建立良好的大学物理演示实验室；合理应用多媒体，优化演示实验情境。中教法实验是高师的特色课程。
This paper briefly introduce that we takeadvantage of old instruments to make some demonstration experiments in our demonstrationlaboratory , which assorted the classroom teaching closely . it declarates that demonstrationexperiments play the most important role as asisted teaching method in the physicsinstruction 本文概要介绍了我系演示实验室利用陈旧设备，紧密配合课堂教学所做的几个演示实验.它说明了演示实验在物理教学中具有其辅助教学手段不可替代的作用
Based on chinese tracking and data relay satellite ( ctdrs ) in the future , the antenna pointing control and complex control theory of user satellite are studied deeply in this dissertation , which is funded by the improve item of dept . of astronautic engineering and mechanics ? “ the teaching demonstration of antenna pointing control system in tdrss ” . the main contents of this dissertation are consisted of the following parts : firstly , dynamics equation is derived using lagrange equation for user satellite , so as the kinetics equations of user satellite at the same time are expressed in the form with matrix differential equations that is suitable for attitude control system design and analysis 本学位论文结合航空宇航科学与技术学科研究生教学基地实验室建设项目“中继系统星间链路天线指向控制系统教学与演示实验” ,以我国跟踪与数据中继卫星系统为背景,对某型号用户星星间链路天线指向跟踪控制和复合控制理论进行深入的研究,研究内容主要包括以下几个方面: 1 .利用lagrange方程建立了用户星的动力学方程,同时推导了运动学方程,并将这组动力学方程以矩阵微分方程形式表示,使之适用于姿态控制系统的设计和分析。
Secondly , it introduces some fundamentals relative to psychology and pedagogy , which provides scientific and theoretic basis for the improvement of the physics experiment demonstration teaching in middle school by means of multi - medium . thirdly , according to the characteristics and laws of physics experiment teaching in middle school , it works out effective measures for teaching , which proves sufficient with plenty if courseware data and investigation . finally , it attacks the trend that some people pursue superficial forms and simple technicalities by means of multi - medium in the physics teaching of middle school , while it also affirms the correct uses of deepening the physics teaching research and refonn in middle school by multi - medium , and has a bold prospect for it 全文主要内容大致分为四个部分：首先，阐述了多媒体技术的概念、特点与功能，论证了其优化中学物理演示实验教学的必要性；其次，介绍了心理学与教育学的相关原理，为利用多媒体技术优化中学物理演示实验教学提供理论依据；再次，根据中学物理实验教学的特点与规律，拟定有效的系列优化方案，并通过大量的课件、数据、调查进行实证；最后，抨击了中学物理教学中使用多媒体的某些追求表面形式、纯技术化的倾向，而对正确使用多媒体技术深化中学物理教研教改进行了充分肯定与大胆展望。
