摘要： 讨论了相对介电函数虚部和消光系数与光吸收的关系，指出吸收系数与消光系数成正比，而吸收系数与相对介电函数虚部成正比是有条件的．
关键词: 介电函数, 消光系数, 吸收系数
Abstract: The relations between absorption coefficient and the imaginary part of dielectric function, and between absorption coefficient and extinction coefficient, are discussed. The absorption coefficient is proportional to extinction coefficient. But it is not always that the absorption coefficient is proportional to the imaginary part of dielectric function.
Key words: dielectric function, extinction coefficient, absorption coefficient
