摘　　要：利用光经过旋光性溶液后,光强的变化计算出光偏振方向旋转的角度,从而计算出溶液的旋光率.分析实验中多种因素对结果产生的影响,并给出了改进的方法,修正最后计算公式.通过实验测量数据,验证理论的正确性.The rotation angle of light polarization direction is calculated by using the change in light intensity after the light passes through the optically active solution,thereby calculating the optical rotation rate of the solution.We analyze the influence of various factors on the results in the experiment,and give the improved method and correct the final calculation formula.The data is measured by experiments to verify the correctness of the theory.
