Two classes of specific binding sites in the polymer matrix were investigated by Scatchard analysis, which indicated that two kinds of complexes between functional monomers and templates were formed before the polymerization process. Comparing with the structure of TNT and acrylamide, one kind of complex between TNT and acrylamide was strongly charge-transfer complexing interaction by p-πcomplex between electron-rich amino group of acrylamide and electron-deficiecy-benzene ring of TNT, the other was hydrogen bonding interaction between amino group (-NH_2) of acrylamide molecule nitro group (-NO_2) of TNT.

Scatchard分析结果表明，在TNT印记聚合物微球中存在两类结合位点，这表明在聚合反应之前，TNT与功能单体丙烯酰胺分子之间存在两种不同类型的作用力而自组装成两类的模板分子-功能单体复合物，一类可能是由于富电子的丙烯酰胺和缺电子的TNT的苯环通过p-π配键而形成的电荷转移复合物，另一类可能是由于丙烯酰胺的胺基与TNT的硝基之间的氢键作用而形成的复合物。

We described that the nitro group is a stronger electron withdrawing and meta activating characters than the imide group, the amino and hydroxy are both electron donating groups and had ortho, para activating characters. The methyl group might have a steric hindrance effect in this reaction. Our results indicated that methyl group at the ortho position of the amino group on the benzene ring, the steric hindrance effect became stronger.

另一方面，由产率上的结果来看，可以得知硝基为强力的拉电子基团，会减少邻位和对位胺基的电子密度比间位多；而氢氧基与胺基是供电子基团，会增加邻位和对位胺基的电子密度比间位多；甲基取代对反应则只有立体障碍的影响，而且与反应的氨基成邻位存在下影响最大。

Thirdly,The nuclear chromatin of lung carcinoma cells concentrate to periphery, the electron density of cytoplasm increased, in some cells,the heterochromatin of nucleus were blurry,and the nucleole became uniform in electron density, the formatio reticularis of nucleole disappeared.

细胞核的改变：细胞核内染色质边集，基质电子密度增高。有些细胞核内异染色质分界不清，核仁呈均一电子密度，网状结构消失。

The performance and mechanism of corrosion inhibitions of POCA were studied bymethods such as weight-loss, electrochemistry, EDS, XPS and quantum chemistry. It isfound that POCA is cathodic corrosion inhibitor, having synergistic effect with HEDP andZn~(2+). The P and O atoms of phosphono have important electron density contribution toHOMO orbital and the electron gross orbital population is bigger than 1, so it is easy toform absorbing location between phosphono and metal resulting in good corrosioninhibition on mild steel.

通过利用失重法、电化学方法、扫描电镜、X光电子能谱、X-射线能谱和量子化学方法研究膦酰基羧酸的缓蚀性能及其机理，发现POCA是一种阴极型缓蚀剂，与HEDP、Zn~(2+)具有优良的协同增效作用；POCA分子中的膦酰基基团的P原子和O原子对HOMO轨道电荷密度贡献较大，且其轨道电子布居数均大于1，因此比较容易通过膦基与金属形成吸附位而对碳钢具有良好的缓蚀作用；对铜合金具有一定的腐蚀作用，但腐蚀作用比HEDP等有机膦药剂要小得多，同时与BTA具有优良的相容性，添加1mg／L的BTA则可以有效地防止铜合金的腐蚀。
