【讨论】固体紫外漫反射得到的光谱纵坐标是吸收值 还用Kubelka－Munk转换吗

可以直接用，因为做之前你已经做了zeor/baseline，0％和100％两个标准已经确定了。

测试时选的是FR模式，得到的谱图纵坐标是FR, 可以直接用吗，FR是什么含义，和A有什么关系啊

一般FR其实就已经帮你K－M变换了。

The Kubelka-Munk theory is generally used for the analysis of diffuse reflectance spectra obtained from weakly absorbing samples. It provides a correlation between reflectance and concentration. The concentration of an absorbing species can be determined using the Kubelka Munk formula:

F(R) = (1－R)²/2R = k/s = Ac/s

R = reflectance
k = absorption coefficient
s = scattering coefficient
c = concentration of the absorbing species
A = absorbance
