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。

On March 30 afternoon,"Industry of mobile electron commerce uses a project " start in Beijing, the 10 big guild of countrywide that this one project governs on somebody's behalf by association of Chinese electron business affairs and Chinese trade union are advanced jointly, by the shift that use friend business affairs company and center of news of trade of China whole nation undertake.

Dispatch of sina science and technology on March 30 afternoon message, the 10 big guild of Chinese that the Chinese trade union such as Chinese textile Trade Association governs on somebody's behalf, with association of Chinese electron business affairs, 30 days are started jointly " industry of mobile electron commerce uses a project ".

新浪科技讯 3月30日下午消息，中国纺织品商业协会等中国商业联合会代管的中国十大行业协会，与中国电子商务协会，30日共同启动了"移动电子商务行业应用工程"。

The inner quantum orbital momentum of electron and the relative quantum distance between atomic nucleus and electron all relate to the quantum state of the atomic system.

证明氢原子系统的量子能量、系统内部电子的量子轨道动量及原子核和电子的量子相对距离均与原子系统所处的量子状态有关。

It is found that the nature of the interaction between CO and Pd(110) surface by population analysis and DOS analysis what the 5σ orbital of CO and the d orbital of metal formed electron donation; and the 2π* orbital of CO and 4s and 3d orbital of metal formed electron back- donation.

通过布居数分析和态密度分析发现， CO 和 Pd(110)表面的相互作用，主要是 CO 的5σ轨道和金属原子的 d 轨道形成5σ-d 配位键；同时 CO 的2π*轨道和金属原子的4s 和3d 轨道形成反馈键。

Upon this we measure the conbination energy spectrum and momentum spectrum of valence orbital electron of C2H6. furthmore we get the isolation spectrum of valence orbital electron of N2 and C3H8 for the first time.

在此基础上，测量得到乙烷分子(C_2H_6)价轨道电子的结合能谱和动量谱，并用EMS方法测量得到氮分子(N_2)和丙烷分子(C_3H_8)价轨道电子的电离能谱。

The exact effective nuclear charge numbers have been defined andcalculated with the mean radius of the initial orbital of the active electron toconsider the combined -effects of relativity and screening in an actualtranstition calculation . The electron impact ionisation cross sections and thecorresponding ionisation rate coefficients of Li like ions 〓、〓、〓、〓and〓 have been calculated by using our calculated effective nuclearcharge numbers.

我们考虑并修正了原始理论中对屏蔽常数物理意义的不正确定义和算法，更精确考虑了其它电子对被电离电子的屏蔽效应以及相对论收缩对有效核电荷数的影响，得到了更可靠的有效核电荷数，并给出了更好的电离截面结果。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。
