演示实验在物理课堂教学中的应用

物理学是建立在实验基础上的一门学科,物理教学应重视对学生的实验教学.而演示实验能以其生动的魅力和丰富的内涵,激化学生的学习热情,提升学生学习物理的兴趣,对学生理解物理概念和规律,培养学生观察、分析与综合能力、收集和处理信息的能力,在培养学生的优良思维品质和创新能力等方面发挥着独特的功能和作用.那么,教学中应怎样安排好演示实验才能使教学效果恰到好处呢?下面简要谈谈演示实验在物理课堂教学中的具体应用.……     

Residential environment index system and evaluation model established by subjective and objective methods

In this research, the residential environment index system and evaluation model were established by means of subjective and objective methods. The methodology for establishing the evaluation system for residential environment was first analyzed; then the subjective evaluation data-base was established by questionnaire survey; and at the same time, the objective evaluation data-base was constructed by Geographic Information System (GIS); and then the related equation system between subjective and objective system was developed by multiple regression analysis. This research could benefit evaluation of the residential environment quality for various purposes, and also provide important rudimentary data-base for the development and improvement of residential environment for officials. Furthermore, the index system and evaluation model established in this research could construct a strong relation between subjective evaluation and objective data; and thus could provide a comprehensive, efficient and effective methodology for the evaluation of residential environment.

Computer support system for residential environment evaluation for citizen participation

INTRODUCTION Citizen participation in urban planning is crucial for satisfying the increasing demand to improve the overall city planning process (Sherry, 1969). The information exchange, opinion feedback, establish-ment of expert system and the development of effi-cient and effective participation methods has brought huge benefits and high potential for the improvement of the whole city planning (Arima, 2001). The public participation system to evaluate the planning system for the speci…

排球技术课多媒体CAI课件的研制与应用研究

运用计算机多媒体CAI课件辅助教学的方法进行教学实践,探讨多媒体教学对提高排球技术课的教学效果.通过问卷调查法和实验法进行研究,结果显示,实验组与对照组学生的学习成绩和学习态度等方面具有显著性差异(实验组优于对照组),98.5%的学生认为多媒体教学的效果好,乐于接受,能有效地帮助他们提高学习效果和学习成绩.说明高质适用的多媒体CAI课件能有效地提高排球技术课的教学效果,值得推广.     

Life cycle assessment in the environmental impact evaluation of urban development—a case study of land readjustment project, hyogo District, Japan

In this paper, the Life Cycle of Urban Development was firstly analyzed, and the phases of Life Cycle Assessment applied to Urban Development (ULCA) were described. As a case study, ULCA was applied in the environmental impact assessment of the land readjustment project of Hyogo District of Saga, Japan. In addition, mitigation proposals for reducing CO2 were also presented and the relevant environmental effects were simulated.     

光子、实物粒子使原子跃迁的区别

一、光子使原子跃迁 原子的跃迁条件hv=Em-En,适用于光子使原子在各定态之间跃迁的情况,当光子能量较大时,与原子作用而使原子电离,产生离子和自由电子时,原子结构被破坏,如基态氢原子的电离能为13．6eV,只要大于或等于13．6eV的光子都能被处于基态的氢原子吸收而发生电离,电离所产生的自由电子的动能等于入射光子能量减去电离能．
