摘要
介绍了JJY分光仪的几种常见调节方式,分析了各个调节方式的异同,通过采用不同调节方法测量了标准三棱镜的顶角大小,并对取得的数据进行对比分析,得出渐近与一步到位二次自准法是最科学的调节方式。其他经验调节方法的测量结果虽然可以达到测量目的,但测量结果严重依赖于操作经验。
This paper introduced several common adjustment methods of JJY spectrometer,analyzed the difference of these methods,measured the apex angle of standard triple prism by the above methods,and comparatively analyzed the obtained data.The results shows that the asymptotic method and one-step to the position auto collimating method are the most scientific methods,while other empirical methods rely on severely operation experiences though they can meet the basic measurement needs.
