The Experimental Research Based on the Natrium's Characteristic Light

提出干涉条纹反衬度测量概念,在迈克耳逊干涉仪上对双黄线的波长与波长差进行测量的原理和方法,并对实验测量过程中波长和波长差数据进行了细致的计算.实验测量结果与理论值一致,达到了预期的效果.利用反衬度方法在迈克尔逊干涉仪上实现对钠光特征谱线一种快捷有效测量方法,所测的数据较精确,对研究钠原子的内部结构提供可靠的实验数据,该测量方法可进一步拓展为物理设计性、应用研究性实验.

The interfeveace fringe gamma survey concept is proposed in the paper. The principte and method for measuring the wavelengra of double yellow lines and its difference in Michael interferometer have been surveyed, and the wavelength and data of wavelength difference from the measuring process has been carefalty calculated. The experimental results are consistent with theoretical values, and met with the expected results. The antion contrast method for natrium light characteristic spectrum realized in Michael interometer is a fast and effective way. The measured data is quite presise, and can provide a retiabete experienmental data to the study of internal structure for Na atom and also, the measuring technique may be further developed for physical designing and application.
