At the B3LYP/6-311+G(3df, 2p) level, the activation energy was obtained with a zero point energy correction.

对反应各驻点进行了全局优化，经过零点能校正后，计算得出乙烯二聚反应的活化能。

Results 22 patients underwent zygoma reduction and subperiosteal rhytidectomy by coronal incision approaching. 5 cases with frontal region depression were filled with ePTEF or a piece of epicranial aponeurosis. The follow-up time was 6～24 months. All the patients were satisfied with the final results.

结果：本组22例患者，均行头皮冠状切口颧骨颧弓复合体缩小及骨膜下除皱术，部分患者以膨体聚四氟乙烯补片或帽状腱膜行中上面部凹陷填充，术后面部软组织及骨性结构均得到显著的年轻化改善效果，随访6～24个月，面部外观满意。

By virtue of the coordination of Cr2L (L = CO; PPh3; C3H5 BF4-) with N-vinylcarbazole, acenaphthylene and their derivatives as organic ligands, a series of organometallic complexes have been synthesized. Their spectra characterization and X-ray diffraction analysis have been performed. It is found that this kind of complexes possesses an electronic structure with highly extensive π- delocalization.

以N－乙烯基咔唑、苊烯及其衍生物作为配体与金属基团Cr2L(L = CO； PPh3； C3H5 BF4-)配位，合成了一系金属有机配合物，并对其进行了光谱表征和单晶X射线衍射分析，发现该类配合物具有高度离域的电子结构。

BACKGROUND: The chief domestic alloplastic material implantation used in augmentation rhinoplasty is silicone rubber. Other materials used are porous highdensity polyethylene and expanded polytetrafluoroethylene (e-PTFE, Gore-Tex).

背景：加高型鼻整形手术中使用的人工合成异体填充物在国内主要以矽胶为主，其它还有膨体聚四氟乙烯(expanded polytetrafluoroethylene， e-PTFE， Gore-Tex)和多孔高密度聚乙烯(porous high-density polyethylene， PHDPE)等。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
