摘　　要：对初、高中阶段的物理实验进行系统总结,从实验的基本组成、测量仪器的构成以及自动控制装置的构成三个方面进行了分析,发现都与"三"有密切联系。掌握了物理实验的基本组成就可以根据需要灵活设计探究实验;掌握了测量仪器的基本构成就可以根据需要自行设计、制作实验器材;掌握了自动控制装置的基本构成就可以设计、组装自动控制装置。通过对物理实验规律的归纳总结引导读者反思实验教学中对科学方法教育的创新和钻研。The paper summarizes the physics experiments in junior high schools and senior high schools systematically and makes an analysis in such three aspects as the basis composition of experiments,the composition of measuring apparatus and the composition of automatic control devices.It is surprisingly find out that all those three aspects are closely related to the numeral ＂three＂.Supposing we master the basic composition of the physics experiments,we can design exploring experiments flexibly in terms of our demands;supposing we master the basic composition of measuring apparatus,we can design and make experimental instruments of our own accord;supposing we master the basic composition of the automatic control devices,we can design and fabricate automatic control devices.By summarizing and inducing the laws of physics experiments,the paper aims to lead the readers to reflect over the innovation and research concerning the teaching of scientific research methods in the teaching of performing experiments.
