The Kubelka–Munk theory is also used in the paper industry to predict optical properties of paper, avoiding a labor-intensive trial-and-error approach. The theory is relatively simple in terms of the number of constants involved, works very well for many papers, and is well documented for use by the pulp and paper industry. If the optical properties (e.g., reflectance and opacity) of each pulp, filler, and dye used in paper-making are known, then the optical properties of a paper made … Web仪器自身带的附件进行转化.有的仪器输出的是漫反射,而有的输出是吸收.也就是说,输出的是反射或吸收主要是由仪器决定的.反射或吸收都无所谓,都可以用于判断能带隙和有无可见吸 …
