摘要
光声光谱技术是近年来用于光合作用研究领域的一项崭新的技术。利用光声光谱技术可以对叶片等生物材料进行无损伤光谱测定。本文应用该技术对几种植物的叶片及花瓣进行了不同层次和深度的光谱扫描,实验结果证明,扫描得到的谱图很好地符合各层次细胞的光吸收特性;相比于其它方法,光声光谱技术具有非损伤检测的优点,可以用来研究植物叶子内部结构和不同层次细胞光能利用情况。
Photoacoustic spectrometer has been introduced for photosynthesis research recent years.The spectrum of leaf or other biological materials can be measured in vivo by this technique.Applied with this method,the scanning spectrum of several kind of plant leaves and petals have been obtained.it is proved that the scan-spectrum is correspondent to the light-absorbing characteristics of each layer respectively.Compared with other techniques,advantages of photoacoustic spectrometer include it s in vivo and conven...
