The most significant improvement was obtained upon introducing Co(superscript 2+) as a modifier. The yield of crotyl alchol reached 5.5%, however the activity lowered from 150.4 mol CAL/mol Ru·h to 96.7 mol CAL/mol Ru·h.

尤其是经Co(上标 2+)修饰后，巴豆醇的最高产率为5.5%，而催化活性由150.4 mol巴豆醛／mol Ru·h降至96.7 mol巴豆醛／mol Ru·h。

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.

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。
