Either electron-donating or electron-withdrawing group linked at the intercalation plane may increase the motility of π-bond and the molecular polarization, thus enhancing the intercalation.

2在刚性平面上引入特定长度的柔性侧链作为导向连接结构，可以增强DNA选择性结合的作用，这说明在抗癌药物设计中柔性侧链的引入可能对增大抗癌活性，降低毒性是有作用的。

The Tianjin Saint peaceful electron Limited company mainly produces the medical instrument product, is another pillar industry which in the Tianjin Saint peaceful electron Limited company multiplication development process rises.

天津圣泰电子有限公司主要生产医疗器械产品，是天津圣泰电子有限公司多元化发展进程中崛起的又一支柱产业。

Penis residual stump was advanced to anterior portion of the newly restoration penile body as "glans"; To take full layer skin of penis from post-operating patients to observe neurofibril regeneration by light microscopy, electron microscopy and scanning electron microscopy; To determine sensation recovery by physical examination; To check erectile function with NEVA System.

修復术中通过离断阴茎浅、深悬韧带，並继续分离部分海绵体脚，使原固定於耻骨下支的阴茎海绵体充分分离，以使阴茎更为延伸；用含血运的脂肪瓣填塞耻骨前间隙，保证术后远期阴茎的有效长度；选用合適的带血管蒂皮瓣转移覆盖海绵体，塑造更为逼真的龟头和冠状沟样外形。

The current was considered as the sheared electron flow, and the Kelvin-Helmholtz instability induced by the sheared electron flow of nightside magnetopause was discussed.

本文将这种电流看成电子剪切流，来讨论夜侧磁层顶的电子剪切流所引起的Kelvin-Helmholtz不稳定性问题。

And, comparing the nightside near earth magnetopause with the magnetotail, we found that when the ratio of electron number densities of magnetopause is constant, and high electron number density can raise K-H instability.

本文对比了夜侧近地磁层顶和磁尾磁层顶，发现当磁层顶两侧电子数密度之比恒定时，高电子数密度的磁层顶侧易产生K-H不稳定性。

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.

3月30日下午，"移动电子商务行业应用工程"在北京启动，这一工程由中国电子商务协会及中国商业联合会代管的全国10大行业协会共同推进，由用友移动商务公司及中华全国商业信息中心承办。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
