Butyric acid,phenol,indol and polycyclic aromatic hydrocarbons are inferredin the solution phase of leachate by GC,and 53% of organic acids,18% of alcohol andphenols,and 7% of alkanes are detected in leachate by GC-MS.The colloidal structure oflandfill leachate is analyzed by determination ofξ-potential and the interfacial tension,whichprovide the basis to pretreatment by the coagulation and treatment by advanced oxidation.

首先测定了垃圾渗滤液的常规水质因子及污染物含量，并采用GC及GC-MS技术对垃圾渗滤液有机相的微观结构进行了分析，由GC谱图解析推断渗滤液的溶液相中含有丁酸或辛酸、苯酚、吲哚及多环芳烃等有机物；由GC-MS解析可知其有机物主要为有机酸，约占53％，其次醇及酚类约占18％，烷烃约占7％。

The recent research progress of oxidation carbonylation of amines/β-amino alcohols, alkoxycarbonylation of epoxides, carbonylative Suzuki coupling, carbonylative Sonogashira, and double carbonylation of aryl iodides has been presented, focusing on the carbonylation reactions studied by us in the past few years, with 81 references.

The analysis on fatty acid,alcohol and ketone of oil with GC-MS method indicates that the alkyl acids,especially those with linear and saturated alkyl acids,are dominant in the newly generated acids.

采用气相色谱-质谱方法，对油样提取物中微生物产生的酸、醇、酮等物质进行了分析研究，两株菌产酸以饱和烷基酸为主，尤其以直链饱和烷基酸居多，同时也生成一定量的环烷、烯基酸和少量的芳基酸。

This tasty tea is known for its even and flat appearance, resembling sunflower seeds. It brews a bright green liquor color with clean aroma, fresh fragrance and a hint sweet mouth-filling taste. The infused leaves are hairless and lovely. Queshe tea is really an extraordinary treasure among other selected teas in northern Qin.

&雀舌&礼品茶品质特征为：外形扁平光滑，形似葵花子状，色泽翠绿，埋毫不露；香气醇郁，清芳悦鼻，汤色清澈明亮，滋味醇厚鲜爽，回味甘爽持久，叶底明亮鲜活，实为黔北原生态优质茶中的一朵奇葩。

Quantitive coordinate solvent-DME was added during the preparation reaction or crystallization, sodium ion in complex 1, 2 and 4 will be extracted and become free one, thus new solvated anion-cation pair complexes [2Ln2][Na22] Ln = Nd (5, Sm (6), Yb (7) were formed.

在反应或者结晶的过程中加入一定量的乙二醇二甲醚，配合物1，2和4中与双芳氧鞠位的钠离子被DME分子萃取出来，生成阴阳离子对配合物[_2Ln_2][Na_2_2]Ln=Nd(5，Sm(6)，Yb(7)。

When the reaction was carried out under the above optimum conditions, the conversion of mandelonitrile was 42 % and e.e.

在此基础上合成氰醇类底物，运用摸索的条件对其进行动力学拆分，并探讨了芳环上的取代基R对反应结果的影响。

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。
