摘　　要： 提出一种有助于提高溶液浓度的选择性测量的新传感方法，讨论了这种方法的理论依据物质反常色散，分析了具有吸收谱的物质复折射率随波长变化的关系，研究了反射率的衰减及衰减全反射现象． A new sensing method was presented, which is advantageous for selective detection of liquid density. The anomalous dispersion which is the theoretical basis of the new sensing method was discussed. The dependence of complex refractive index of matter having absorption band on wavelength was analyzed. The attenuation of reflectivity and the attenuated total reflection were studied. Initial experiments show that the sensing method is feasible.
