摘　　要：透明溶液浓度是表征溶液特性的重要参数。介绍了基于中空三棱柱透镜测量透明液体浓度的实验方法,利用平行光线照射盛有待测溶液的中空三棱柱透镜,通过CCD拍摄并测量折射光线的偏移量,从而确定待测溶液的浓度。研究结果表明,利用标定的浓度刻度尺能够直接测出待测液体的浓度,对氯化钠溶液和葡萄糖溶液的浓度进行测量,其相对误差分别为0.6%和1.6%。The concentration of transparent liquid is an important parameter for the characteristics of the solution.This experiment provides a method to measure liquid concentration based on Hollow Prism Lens.The parallel light is used to illuminate the triangular lens with a solution.The refraction light offset is measured by the CCD to obtain the liquid concentration.The result shows that the liquid concentration can be measured based on the Hollow Prism Len by using a calibrated concentration scale.The liquid concentration of[JP2]sodium chloride solution and glucose solution are measured based on this method.The relative errors are 0.6%and 1.6%,respectively.
