The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.

丙烯氧化反应体系的原位漫反射红外光谱研究结果表明，由丙烯脱氢生成的烯丙基中间物种吸收峰在1454cm~(-1)和1427cm~(-1)处；基于此提出了较完整的丙烯氧化反应网络：丙烯选择氧化生成丙烯醛主要经历丙烯脱除甲基上的一个H，生成烯丙基物种，该物种嵌氧生成σ-O络合物，脱氢得到丙烯醛前驱体，脱附生成丙烯醛；完全氧化产物是由催化剂表面上生成甲酸盐、羧酸盐、碳酸盐等形式的中间物种转化而成；较低反应温度下丙烯氧化生成丙酮，通过烯醇式中间物种氧化生成丙酮前驱体得到。

Results After TBI the MRI performance is the T1WI low signal or the equisignal and the T2WI high signal.4 h after TBI,water content of brain tissue and EB content in the contusion side significantly increased,the expression of AQP-4 mRNA and the protein expression of AQP-4 in contusion marginal region began to increase.

TBI后4 h伤区脑组织含水量及EB含量开始增多，AQP-4 mRNA、AQP-4蛋白表达开始增高并逐渐上升，24 h达到高峰，随后逐渐下降，伤后72 h仍维持在较高水平(P＜0.05)。

Therefore, the previous data of heats of formation of polynitrocubanes estimated from groupadditivity method are corrected.3. Calculations indicate that, for polynitrocubanes, there are parallel relationships between their experimental kinetic acidities pKa, the average s characters in the exocyclic carbon orbital used for the C-H bonds within each molecule, and the average C-H stretching frequencies within each molecule.

计算结果表明，多硝基立方烷的实验动力学酸性pK_a、分子内用于形成C-H键的环外碳轨道平均s成分和分子内的平均C-H伸缩频率之间，存在平行的递变关系，这对基于s_a或v_a的数值预估动力学酸性pK_a、进而指导多硝基立方烷和其它相关化合物的合成有助。

Methods Peripheral blood neutrophils were islolated from health men, and then cultured in DMEM medium containing 10% fetal calf serum for 3 h. Blank medium or gonococcal inocula was added into group A or group B. NO concentration and iNOS mRNA expression at 0, 3, 8 and 12 h were determined by cadmium reduction method and realtime quantitative fluorescent PCR, respectively.

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.
