Structures of Na~+-AD ion-complexes with 1 or 2 H2O molecules were obtained. It was found that H2O can bond with Na~+ in the structure of Na~+-AD to form Na-O van der Waals bond. H2O molecule can also bond with N or O atoms in AD moiety to form H-bonds as N-H…Ow or O…Hw-Ow. The former process takes place more easily. The most stable structures of Na~+-AD ion-complexes with 1 and 2 H2O molecules are W-C7AB and 2W-C7AB, respectively.αB conformer of Na~+-AD can not exist in the presence of 2 H2O molecules.

研究发现水分子可以结合在Na~+-AD络合离子中的Na~+附近形成Na-OW范德华键，也可以与Na~+-AD络合离子骨架结构中电负性较强的N或O原子结合形成N-H…OW或O…HW-OW氢键，相对而言，水分子更容易结合在Na~+-AD络合离子中的Na~+位置，Na~+-AD最稳定的带1个或2个水分子的结构分别为W-C7AB和2W-C7AB，Na~+-AD络合离子的αB构象在2分子水存在的情况下完全消失。

Were extracted by different extracting solvents in lab, the results indicated that with the increasing of Mn concentration levels, the speciation of Mn in their roots transform from H2O-extractable species to HCl-extractable species and NaCl-extractable species, showed increases of Mn of oxalate binding and pectate binding or prontein binding in cell wall of roots; Mn of H2O-extractable species were 34.55～50.26% of total Mn in stems and increased with the increasing of Mn concentration levels, which benefited upward transport of Mn; Percentage of Mn of H2O-extractable species were 38.55～44.19% and Mn of HCl-extractable species were 20.66～28.74% to total Mn in leaves, suggesting that most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. 5.

不同的提取剂对水蓼根、茎、叶的提取结果表明，随着锰处理浓度增加，水蓼根中Mn由水提取态向盐酸提取态和氯化钠提取态转化，说明根细胞壁结合的草酸盐和果胶酸盐或蛋白质结合态的Mn含量随锰处理浓度的增加而增加；在茎中，水提取态锰含量占总锰的34.55-50.26%，且随锰处理的增加其水提取态锰的比例增加，这有利于锰向上运输；水蓼的叶片中，水提取态锰占总锰的38.55-44.19%，盐酸提取态锰占总锰的20.66-28.74%，说明叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在。

Membrane affinity quantified by IAM and liposome/buffer systems was a more efficient predicator of α values than hydrophobicity from n-octanol/buffer system. Consequently, not only hydrophobic force but also attractive polar extra-interactions involved in the binding to IAM and liposomal membranes but not in an n-octanol phase, ascribed to the binding process within AM. The binding to ordered lipid membrane in the larger part determined drugs'binding to AM intracellular compositions, and the ordered phospholipid plasma membrane was a potential site for drugs'binding in AM.

脂质体／水系统和磷脂膜色谱所测定的膜亲和性比正辛醇／水系统的疏水性更好的预测巨噬细胞内药物的α值，因此包含在磷脂膜色谱中但并不体现在正辛醇／水系统中药物与磷脂膜之间的额外吸引性极性作用力对药物在细胞内结合有着重要贡献；药物与有序磷脂膜的结合在很大程度上决定着药物与巨噬细胞内成分的结合，有序磷脂分子膜可能是巨噬细胞内部潜在的结合部位。

For the high affinity sites, binding constant decreases with the decrease of the alkyl chain lengh in the surfactants, but for the low affinity sites, binding constant increases and are not distinct when the alkyl chain is dedocyl. The binding sites are related to the alkyl chain lengh, not for the number of hydrophile groups and temperature.Isothermal titration calorimetry has been used to observe the enzyme-catalyzed hydrolysis reaction of urea.

对于高结合位点，结合常数随疏水碳链长度的减小而减小；对于低结合位点，结合常数随疏水碳链长度的减小而增大，相应的当碳链减小至C12时，低结合位点不明显，结合位点数可能只与碳链长度有关，随亲水头基和温度变化不明显。

Templating agent could not be sufficiently removed at temperature below 500℃, while temperature exceeding 600℃ might result in collapse of the framework. The conversion from Co(superscript 2+) to Co(superscript 2+) was a gradual time-consuming process. Calcination at 550℃ in a muffle furnace for 10 hours could remove the templating agent and bond water and give a satisfactory result.
