摘　　要：介绍了一种用于液体浓度测量的棱镜内反射传感方法 .讨论了在入射角小于临界角和入射角大于临界角两种情况下反射光能量与浓度的关系 ,给出了测量浓度的实验装置和两种实验方法 .实验结果及分析表明 ,这两种方法用于测量液体浓度是可行的 。A sensor method is for measuring liquid density based on prism internal reflection. The relationship between the energy of reflection light and liquid density is discussed at the two kind of incident angle less than or more than critical angle, the experiment setting and two methods for measuring liquid density are also presented. The experimental results and the analysis show that the proposed methods are feasible and have a wide applicable prospect.
