To improve the IR absorption of hydrotalcite, we intercalate SO 42 - to partly replace CO 32 - of interlayer.对水滑石红外吸收机理的研究表明,水滑石的层间阴离子起主要作用, 层板具有协同效应.为提高水滑石的红外吸收选择性,通过对不同阴离子的分析和筛选,确定在水滑石层间插入硫酸根.Veiws evidently intercalat...
The fields are crisscrossed by irrigation canals and ditches.田野上沟渠纵横.We moved through fields and over ditches.我们穿过田野,跨过沟渠.The rain has filled up the ditches again.雨水又把沟渠给灌满了....
