摘　　要：采用阿贝折射仪测量研究了溶液折射率与溶液浓度的关系,结合线性最小二乘方法建立了回归方程,并将其用于溶液浓度的预测,获得了比较理想的预测结果.Abbe Refractometer is adopted to measure the refraction index of single- and double- component solutions. And the relationships between the refraction index and solution concentration are fitted by linear least square method. Based on these models, unkown concentrations of sucrose and sodium chloride solution are predicted. The predicted results agree well with their normal values.

关 键 词：折射率 浓度 线性回归
