摘要
采用化学分析、热分析和红外光谱分析技术对土娄土、黑垆土不同结合态胡敏酸的性质和结构进行了研究。结果表明，胡敏酸结合的牢固程度不同，其性质结构也各异。稳结态和松结态胡敏酸相比，前者芳构化度高、缩合度大、分子颗粒大、分散度小、羧基含量多；后者脂肪族增多、活化度高。
In this paper, the different combined humic acids of Lou soil and Heilu soil were studied by using chemical analysis thermol analysis and infrared spectrum. Results showed that the properties and structures of humic acids were different with different combined manners. Compared stably combined humic acid with loosely combined humic acid, the former was stronger in aromaticity, bigger in polycondensation and molecular particle, less in dispersion degree, more in carboxy group and higher in oxidation degree, while the later was stronger in fatness and higher in active degree.
