SM6 and SM7 of uncrystal were analyzed through GC-MS, the results showedthat SM6 main contained unsaturated fatty aldehyde with fragrance, i.e.-2,4-decadienal(58%), tetradecanoic acid (55.78%), 2-decenal(50%), Phthalic acid isobutylundecyl ester(47%), 2, 4-Decadienal(41%), 2-Undecenal (31%), 2-Methyl-Z,Z-3, 13-octadecadi-enol(18.84%), and SM7 contained saturation alkanes, i.e. 1, 2-Benzenedicarboxylic acid, butyl cyclohexyl ester(23.90%), Triacontane(22.63%),Nonacosane(21.04%), Heptadecane(18.84%), Octacosane(13.58%). Toxicological experiments were done to insure the pigment safety.

并对紫红丝膜菌色素非晶体部分的黄色油状物SM6和紫色粉末物SM7作了GC-MS分析，结果显示SM6中主要为具有香气成分的不饱和脂肪醛，其中含量较高的依次为：-2，4-癸二烯醛(58％)、十四烷酸(55.78％)、2-癸烯醛(50％)、邻苯二甲酸异丁基十一烷酯(47％)、2，4-癸二烯(41％)、2-十一碳烯醛(31％)、2-甲基-Z，Z-3，13-十八碳二烯酸(18.45％)等；SM7中主要为饱和直链烷烃，其中含量较高的依次为：1，2-苯二羧酸丁基环己酯(23.90％)、三十烷(22.63％)、二十九烷(21.04％)、十七烷(18.84％)、二十八烷(13.58％)。

Foreign atoms were placed over the sheet at several symmetrical positions, namely, over a carbon atom, over a C-C bond, over the center of a pentagonal, hexagonal, and heptagonal ring. The following conclusions have been drawn: The cohesive energy of adsorbate and perfect sheet at all three adsorption sites is always lower than that on a sheet with a Stone-Wales defect embedded at all five sites.

得到的主要结论如下：所有外来原子在含有Stone-Wales缺陷的石墨烯片上不同位置上吸附的结合能都大于在其在完整石墨烯片上不同位置上的结合能，因此在碳管中引入Stone-Wales缺陷能够提高原子在碳管上的吸附能力，同时提供了很多稳定的吸附位置。

An atom other than carbon in the structure of a heterocyclic compound.

The stable carbon isotope values of α-,β-,and γ-hexachlorocyclohexane isomers were determined by GC-C-IRMS,EA-IRMS,and Dual-inlet IRMS in this study.

应用GC-C-IRMS技术分析了水样品中α-和γ-六六六的碳同位素组成，结果表明六六六在溶解、稀释、萃取、挥发等过程碳同位素组成没有分馏现象。

To enrich and isolate different function hydrocarbon-degrading bacteria from long-term oil-contaminated environment, crude oil and hexadecane were used as sole carbon sources respectively. On the other hand, bacterium community structures of enrichment were analysed by both plate method and PCR-DGGE (denaturing gradient gel electrophoresis) method.

中文摘要：以原油和正十六烷为唯一碳源，从长期受石油污染的环境中富集和分离具有不同功能的石油烃降解菌，并利用平板法和PCR-DGGE法对不同碳源富集到的菌群结构进行分析。

The result indicated that the cellular fatty acid compositions of Salmonella, Escherichia coli, Vibrio and Shigella all contain tetradecanoic acid, hexadecanoic acid and octadecenoic acid, the total content is around 90%, in which the hexadecanoic acid is the most, above 40%, next is the octadecenoic acid, around 30%.

结果表明：沙门氏菌属、埃希氏菌属、弧菌属和志贺氏菌属全细胞脂肪酸组分都含有十四烷酸、十六烷酸和十八碳烯酸，这三种脂肪酸占总脂肪酸含量的90%左右，含量最高的是十六烷酸，含量在40%以上，其次是十八碳烯酸，含量在30%左右。

Kinds of fatty acids were detected by method 1 and 24 fatty acids were detected by method 2. The results showed that the main components of the fatty acids in pomegranate seeds are: octadecenoic acid, octadecdienoic acid, docosanoic acid, hexadecanoic acid, octadecanoic acid, eicosenoic acid and eicosanoic acid.

方法一共检测出14种脂肪酸，主成分为油酸、亚油酸、山嵛酸、棕桐酸、硬脂酸和二十碳烯酸；方法二共检测出24种脂肪酸，主成分为棕橺酸、硬脂酸、花生酸、山嵛酸、油酸、亚油酸、二十碳烯酸等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
