Translations:Dictionary:Absorption/6/zh

Absorption terminology. Sometimes this terminology is used for attenuation because of factors other than absorption. E = energy, $\Delta E$ = energy lost in one cycle, $\lambda$ = wavelength, f = frequency, x = distance, t = time, ${\frac {A}{A_{0}}}={\frac {\text{amplitude}}{\text{initial amplitude}}},{\frac {A_{1}}{A_{2}}}={\frac {\text{amplitude}}{\text{amplitude one cycle later}}}$.
