PowerPoint articles: explain how to make presentations, how to insert in presentations to other objects, how to use PowerPoint flowcharts and Flash, and how to package your presentation and so on.

PowerPoint篇：讲解了如何制作演示文稿，如何在演示文稿中插入其它对象，如何在PowerPoint中使用流程图和Flash，以及如何打包演示文稿等。

In a large-scale laboratory, often because the target is too small demonstration, too, leading many people can not see the scene of the demonstration, the impact of the demonstration effect, this time on the physical projection booth can be applied to function, Demonstration of the demonstration to the projection screens showing real-time or on TV.

在大规模的实验室中，往往会因为演示者的目标太小、太远，导致很多人没有办法看清楚现场的演示过程，影响演示的效果，这时候就可以应用展台实物投影功能，把演示者的演示过程实时放映到投影屏幕或是电视机上。

In this paper, first of all, the common approaches of demonstrating experiment in general physics are systematically analyzed, including magnification, comparison, transformation, simulation, balance and unbalance, stroboscope, trace-show, projection, etc. In addition, a great number of practical examples exhibit that these approaches can be successfully applied to the physical demonstrating experiments. Then, some specific experimental means are thoroughly investigated from the view of technique, combined with the content of demonstrating experiments in general physics.

本文首先对普通物理演示实验中常用的实验方法如放大法、比较法、转换法、模拟法、平衡法和失衡法、频闪法、示踪法、投影法等做了比较详细、完整的分析，并通过大量实例说明了这些方法在物理演示实验中的应用；然后结合普通物理演示实验内容就一些具体的实验方法从技术实现的角度进行了分析研究。

In addition, this thesis also simulates the movement of the mechanism by simulation method based on Pro/E software. The design error of the head of linking board in the mechanism δ_1 and the initial position error of the cutting torch δ_2 are selected and compared.

为了让操作人员更直观的了解了该机构的运行原理、机构设计和使用方法，本文还运用3DS MAX软件制作了两个演示动画：第一个动画演示了回转机构的割枪作以割嘴为固定点的定心圆锥摆动；另一个演示了整个机床切割矩形轮廓和圆形轮廓时的运动情景。

This article introduces the factures and demonstration circs of a demonstrator of overweight and zero gravity which shows their data and whose demonstrational effect is very good.
