Dihydrojasmone was synthesized from2-hexyl-5-methyl-1,2-oxaborolane,prepared frommethyl vinyl ketone and hexene,via the homologationwith 〓 followed by PCC oxidation and intra-molecular condensation.In stead of the oxidation ofthe C-B bond of 1,2-oxaborolane,fluoride inducedhalogenation of 2-alkoxy-1,2-oxaborolane was found togive 3-halopropanol.

硼氢化甲基乙烯基酮和已烯得到的2-已基-5-甲基-1，2-氧硼杂环戊烷与〓反应，再经PCC氧化，分子内缩合得到二氢茉莉酮。1，2-氧硼杂环戊烷的C-B键除氧化断裂之外，也能够在〓或KF作用下卤化断裂成碳卤键。

It was found that more branch-2 olefin and C5~C6 isoparaffin molecules existed in MIP naphtha. The cause of MIP naphtha having higher octane number and less octane loss during hydrotreating could be explained by the octane model of C6 hydrocarbons quantitatively.

通过对MIP和FCC汽油组成分析，发现MIP汽油组成含有较多的多支链烯烃、异戊烷和异己烷，基于碳六烃的辛烷值模型，可以定量地解释MIP汽油辛烷值高和加氢MIP汽油辛烷值损失低的原因。

The paper discussed how docosahexaenoic acid regulated transcription expression of lipogenic and lipolytic genes, which included PPARγ(peroxisome proliferators activated receptor γ), SREBP-1c (sterol regulatory element binding protein-1c), FAS, HSL (hormone-sensitive lipase) and TGH.

The pathogenic bacterium of prepartum and intrapartum infectious pneumonia mostly were G- bacilli,the pathogenic bacterium of postpartum infectious pneumonia mostly were G- bacilli and staphylococcus aureus.6.The drug resistant rates of G- bacteria to penicillins,cephalosporins,and monocyclicβ-lactam antibiotic were high,However,their compound of addingβ-lactamase inhibitor agents was relatively low resistance,and all G- bacteria were sensitive to carbapenem antibiotics.

产前及产时感染性肺炎的病原菌以G-杆菌多见，而产后感染性肺炎的病原菌主要为G-杆菌和金葡菌。6.G-菌对青霉素类、头孢菌素类及单环类的β内酰胺类抗生素耐药率高，但对其添加β内酰胺酶抑制剂的复合制剂耐药率较低，对碳青霉烯类抗生素均敏感；金葡菌对苯唑西林耐药率低，对万古霉素均敏感。7。

The result of analysis by GC-MS was shown that fatty acid constituents of oat oil were myristic, palmitic, stearic, oleic, linoleic, linolenic and eicosenoic acids.

通过GC-MS分析，燕麦油的主要成分有豆蔻酸、棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸、二十碳一烯酸。

The uptake of CNTs by Stylonychia mytilus and their distribution during the dividing process of the cells were observed with optical microscope for the first time. The dose-effect relationship between concentration of CNTs and surviving rate of Stylonychia mytilus was measured.

自从1991年11月日本电气公司基础研究实验室的饭岛钝雄发现碳纳米管以来，其作为一种新型的纳米材料，已成为富勒烯领域的一个主要的研究热点，被广泛应用于物理、化学、材料等各个领域。

Fermentation for Eicosapentaenoic Acid production by Nitzschia laevis at various temperature between 10℃ and 30℃ was investigated and the dynamics characteristics during fermentation process were also analyzed.

本文考察不了同温度（10℃～30℃）对硅藻合成二十碳五烯酸的影响，对不同温度下的发酵过程进行动力学特性分析。

Results11 separated constituents were identified, the contents of 3 compounds were over 20%. The main constituents in extracts were Bis(2-ethylhexyl) phthalate (21.51%), Nonacosane (25.73%), Stigmastan-3,5-dien (25.73%).

结果从海南裂叶山龙眼叶超临界二氧化碳20 MPa压力提取物中共分离出11个组分，全部进行了鉴定，其中含量高于20%的有3个，为邻苯二甲酸二(2-乙基己基)酯（21.51%）；二十九碳烷（25.73%）；3，5-二烯豆甾烷（25.73%）。

Producing AmpC and ESBLs are higher than that to Klebsiella producing AmpC but nonproducing ESBLs. The genotypes of Klebsiella producing AmpC are mainly DHA type. Imipenem is the first choice of the antibiotics against Klebsiella carrying 2～6 kinds of resistance genes in clinic.

克雷伯菌产AmpC酶和同时产ESBLs的耐药性比单纯产AmpC酶的耐药性更高、更显著；肺炎克雷伯菌产AmpC酶的主要基因型为DHA，对同时存在2～6种不同类型耐药基因的克雷伯菌，碳青霉烯类药物亚胺培南的体外活性最好。
