简答题
吸光度与透光率的换算 (1)将吸光度为0.01,0.30,1.50换算为透光率; (2)透光率为10.0%,75.0%,85.5%换算为吸光度。
正确答案
(1)
∵A=log(1/T)∴logT=-A=-0.01,∴T=10-0.01=97.7%
∴logT=-A=-0.30,∴T=10-0.30=50.1%
∴logT=-A=-1.50,∴T=10-1.50=3.16%
(2)
A=log(1/T)=log100/10=log10=1.00
A=log(1/T)=log100/75=log1.333=0.125
A=log(1/T)=log100/85.5=log1.17=0.068
