光聲光譜可研究物體光致放熱機制。本文對光聲光譜原理與應用作一簡單
介紹，並說明其於光合作用研究上的初步應用。實驗可量得碳棒、碳粉、
薄荷、非洲鳳仙、黃金榕老葉、綠化葉、幼葉之光聲訊號，比較鳳仙與黃
金榕正、反面光聲訊號差異。最後量取黃金榕老葉正、反兩面的反射、透
射、吸收光譜，以Kubelka-Munk理論雙層、單層、指數遞減模型分別求出
吸收係數互相比較。

Photoacoustic Spectrascopy may be applied to study the
mechanism of photo-induced heat releasing of many objects. In
this paper the principle and application of Photoacoustic
Spectrascopy are introduced. The Photoacoustic signal from
carbon bar, carbon powder and leaves can be measured. We may
compare the photo- acoustic signal from the upper side and
lower side of the leaf. At last we apply the Kubelka-Munk
theory to simulate the absorp- tion coefficient of leaves.
