摘要
实验根据葡萄糖溶液浓度不同对折射率的影响,采用光拍法测定液体的折射率,计算出液体的密度,并采用最小二乘法进行线性拟合,最后发现葡萄糖溶液的密度和折射率几乎呈线性关系。
This experiment depending on the glucose solution concentration on the influence of refractive index,determination of refractive index of liquid using light beat method,calculation the density of the liquid,and the use of method of minimum squares fitting,as it turns out,density and refractive index nearly linear relation of the glucose solution.
