摘　　要：在现有理论基础上,利用汞光谱色散实验测出汞光谱8条谱线对棱镜的折射率后,通过多项式拟合得到了波长和折射率的经验关系,即色散特性函数,并由此得到了汞光谱的角色散率.本文有助于人们更深入认识色散现象.Based on the existing theory, the refractive index of eight spectrums for mercury spectrum is ob- tained by a dispersion experiment. The empirical formula of dispersion function for wavelength and refractive index is presented by the polynomial fitted and the angular dispersion of mercury spectrum is also obtained. This is bene- ficial to people understanding dispersion further.
