Q: Has there been any actor you're starstruck to have seen?

问题： 有哪一个演员你见了之后就像追星族一样扑上去的？

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。
