调查表明,大骨节病区的环境特点是低硒高腐植酸。通过病区改水防治实验,收到良好效果。但腐植酸对硒作用机理,至今国内文献报道很少。在探索大骨节病病因时,研究它们之间的关系是必要的。本文用红外光谱法作定性研究,以进一步提供病因线索。 Survey shows that the characteristics of KBD ward environment is characterized by high humic acid. Ward to water through the prevention and control experiments, received good results. However, humic acid on the mechanism of selenium, so far little domestic literature. In exploring the cause of Kashin-Beck disease, the study of the relationship between them is necessary. In this paper, qualitative research by infrared spectroscopy to further provide clues to the cause.
