【摘要】 “研究型”物理实验的开设对激发学生的求知欲、拓宽其知识面、培养其创新思维能力等方面具有重要意义.文章以迈克耳逊干涉仪实验为例,通过在实验装置中增设可调压强的气室和CCD图像采集系统,实现对干涉图样的实时观察和气体折射率的较精确测量.实验设计还考虑到了实验内容及其难度的可深入与拓展空间,具有很强的研究型实验特点,并且可以根据适当的教学设计将此实验开设成综合性或设计性实验.更多还原

【Abstract】 The research-type physical experiments play very important role to excite the students′ thirst for knowledge,widen the range of knowledge,cultivate the innovative and research ability.As an example,a research-type experiment,the measurement of gas′ refractive index by using Michelson interferometer and CCD system,is designed and putted in practice.The developmental space in content and complexity is considered in the design of experiment.It is indicated that the experiment has the obvious characters of research and very suits to study as research-type experiment for students.更多还原
