We used phospholipid fatty acids (PLFA) to determine microbial biomass and community structure in the
sediments of eight boreal lakes with different loadings of allochthonous organic carbon and total...
二元类水滑石层板组成、结构与性能的理论研究（Theoretical Studies on Layer Composition, Structure and Properties of Hydrotalcite)
类水滑石 静电势能模型 热稳定性
2010/8/24
采用晶体学理论建立二元类水滑石(LDHs)微观结构模型与静电势能模型，将层板金属离子间距、层板电荷密度、层间阴离子间距等微观结构参数定量化，并将层间阴离子的静电势能表示成层板金属离子半径和物质的量之比、插层阴离子尺寸和电荷的函数。研究结果表明：LDHs层板金属离子间距应用离子紧密堆积来估算和孔径按阴离子平面六方点阵分布来计算是可行的；调变层板金属离子种类与物质的量之比影响层间阴离子的稳定性，势能计...
