中文摘要:以3种标准粘土矿物伊利石、高岭石和蒙脱石为材料,研究其中红外光谱(包括透射光谱、衰减全反射光谱和光声光谱)的特征。3种粘土矿物的中红外透射光谱均存在3个主要的吸收区域(3000~3800cm-1,1300~1800cm-1和500~1200cm-1), 且吸收特征明显不同;3种粘土矿物的中红外衰减全反射光谱的差异主要表现在800~1200cm-1,其他区域差异不明显;而3种粘土矿物的中红外光声光谱特征与透射光谱相近,但3个吸收区域具有更丰富的吸收特征。应用中红外光声光谱分析表明,海伦黑土为富含蒙脱石的偏中性土壤,长武黄土为富含蒙脱石或伊利石的碱性土壤,而祁阳红壤为富含高岭石的酸性土壤。

Abstract: Characterization of three source clay minerals, illite, kaolin and montmorillonite, were made using three mid-infrared spectroscopic techniques (attenuated total reflectance (FTIR-ATR), transmittance spectroscopy, and photoacoustic spectroscopy (FTIR-PAS)). For the FTIR transmittance spectra, there are three main absorption regions: 3000~3800cm-1,1300~1800cm-1, and 500~1200cm-1, and sharp differences can be found in each region. For the FTIR-ATR spectra, there are absorptions with main difference in the region of 800~1200cm-1. For the FTIR-PAS spectra, there are also three similar absorption regions as FTIR transmittance spectra. However more information is found in the FTIR-PAS spectra comparing with FTIR transmittance absorptions. The FTIR-PAS was applied to identify three soil types and the results revealed that: Hailun soil was characterized as montmorillonite type soil with medium calcium carbonate content, Changwu soil was characterized as montmorillonite/illite type soil with high calcium carbonate content, and Qiyang soil was characterized as kaolin type soil with low calcium carbonate content

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
