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.
