(ab sorp’ sh∂n or ab zorp’ sh∂n)

1.地震波在介質中傳播時一部分能量轉換為熱的過程。地震波吸收的數量級通常是0.25dB/cycle,甚至可達到0.5dB/cycle,也就是每周0.25或0.5分貝。

能量的吸收和振幅及速度隨著頻率的變化有關,所以吸收是高頻能量衰減以及波形變化的原因之一。

2.放射能變為其他形式能量的過程。

3.一種物質的分子或離子進入某種固體或液體內部的過程。

Absorption terminology. Sometimes this terminology is used for attenuation because of factors other than absorption. E = energy, = energy lost in one cycle, = wavelength, f = frequency, x = distance, t = time, .[1]
