物理现象在时空的展现上是千姿百态的。而物理问题的研究,一开始总要在具体事物中抽象出理想模型进行研究,然后再回到具体事物中去。模型的抽出是物理教学中常用的方法。在实际的实验操作中总是存在着多种因素的干扰,使实验结果有一定的偏差。而在多媒体的使用中这些都将以你所需要的姿态展现在学生面前。 Physical phenomena are varied in the presentation of space and time. The study of physics problems always begins with the abstraction of the ideal model for research in concrete things, and then goes back to concrete things. The extraction of the model is a commonly used method in physics teaching. In the actual experimental operation, there are always many factors of interference, so that the experimental results have a certain degree of deviation. In the use of multimedia, these will be presented to students in the way you need.
