R-1,c-2, t-3, t-4-1,3-bis(4-biphenyl)-2,4-di(4-pyridyl)cyclobutane was obtained in diluted sulfuric acid by photodimerization reaction.

通过反-1-(4-联苯基)-2-(4-吡啶基)乙烯在稀硫酸中的光二聚反应合成了r-1，c-2，t-3，t-4-1，3-双(4-联苯基)-2，4-二(4-吡啶基)环丁烷。

If we adopt normal methods to exploit,we can not have any economic benefit,but if we adopt double step horizontal wells,it can increase drainable area greatly,enhance individual well producing rate, achieve the Tarim Oil field's exploiting rule of\"wide spacing,high production\".

若采用常规方式开采，毫无经济效益，而利用双台水平井可大大增加泄油面积，可提高单井产量，实现&稀井高产&的开发效果。

Comparative studies of double balloon enteroscopy and barium enteroclysis in etiological diagnosis of small bowel diseases

目的比较双气囊小肠镜与小肠稀钡灌注和胶囊内镜检查在小肠肿瘤诊断中的诊断率和准确率。

The diluent solution of glyoxylic acid and oxalic acid was used as the separation object.TOA (in n-octanol) was used as the solvent. The extraction characteristics of single acid and two-acid solution were studied,and the influence of pH and the concentration of complexing agent on the distribution coefficients were measured. The suitable mathematic models were proposed to describe the relationship between TOA and carboxylic acid based on assumed extraction reaction in organic phase.

摘 要：以草酸和乙醛酸的稀溶液为分离对象，采用三辛胺为萃取反应剂、正辛醇为稀释剂，研究了单溶质、双溶质有机酸的萃取分离特性，测定了溶液pH值、萃取反应剂的浓度等因素对双溶质有机酸萃取的影响，提出了萃取的化学反应发生在有机相中的假定，建立了TOA萃取草酸的数学模型。

Detection results showed samples VA2, VA7 and VA8 from Malvastrum coromandelianum had weak reaction with MAb SCR18, and samples X2 from Siegesbeckia orientalis had weak reaction with MAb SCR18 and SCR106, while other samples had no reaction with MAbs.

用双生病毒兼并引物PA、PB对杂草样本进行特异性的PCR检测，结果发现仅有赛葵样本VA2、VA7、VA8和稀硷样本X2出现约500bp条带，说明这些杂草上存在双生病毒。

Accordingly, the 16-carbon acid with one double bond is hexadecenoic acid and has the trivial name palmitoleic acid.

据此，有一个双键的16C酸即为hexadecanenoic acid十六稀酸，俗名称为棕榈油酸。
