摘　　要：本文利用分光计装置,以蔗糖溶液为研究对象,通过调配不同质量分数的蔗糖溶液倒入三棱柱容器,测量其对应的最小偏向角,结合折射率公式,得出不同偏向角所对应的溶液质量分数,再将质量分数与偏向角进行数学建模,就可在只测出偏向角的情况下得出蔗糖溶液的质量分数。这一方法对于其他透明溶液或者气体的质量分数测量也同样适用。This paper uses a spectrometer device and takes sucrose solution as the research object.By mixing different mass fractions of sucrose solution into a triangular prism container,the corresponding minimum deviation angle is measured,and combined with the refractive index formula,the solution mass fractions corresponding to different deviation angles are obtained.Then,the mass fraction and deviation angle are mathematically modeled,and the mass fraction of sucrose solution can be obtained when only deviation angle is measured.This method is also applicable for measuring the mass fraction of other transparent solutions or gases.
