摘　　要：利用迈克耳孙干涉仪测量蔗糖溶液的质量分数,在光路中加入装有蔗糖溶液的玻璃杯,逐渐向玻璃杯中加入蔗糖,改变蔗糖的质量分数,进而改变蔗糖的折射率,通过记录相应干涉条纹的变化,计算出新溶液的质量分数.A method for measuring the mass fraction of sucrose solution using Michelson interfer-ometer was introduced ,and the experimental scheme was designed .A glass container filled with su-crose solution was inserted in the light path of the interferometer .The refractive index and mass frac-tion of the sucrose solution was changed by adding sucrose ,and the sucrose mass fraction was deter-mined by measuring the number of fringes changed .This method extended the application of Michel-son interferometer in teaching and research .

关 键 词：迈克耳孙干涉仪 质量分数 折射率 干涉条纹
