红外光谱法作为有机物结构研究的一种重要手段，已在土壤有机质研究中得到广泛应用，特别是近年来傅里叶变换红外光谱的引入以及与色谱的联用，更使这方面研究获得较大进展。本文就此进展作一概述。 Infrared spectroscopy as an important means of organic structure research has been widely used in the study of soil organic matter, especially in recent years, the introduction of Fourier transform infrared spectroscopy and chromatography, but also make this study to obtain larger progress. This article gives an overview of this progress.
