查询词典 fragment

Description Logic is a kind of object based knowledge representation formalism, and also a decidable fragment of first order predicate logic, with well-defined semantics and powerful representation capability.

描述逻辑是一种基于对象的知识表示的形式化系统，它是一阶逻辑的一个可判定的子集，具有合适定义的语义，并且具有很强的表示能力。

Accordingly, a new plasmid Cm1301 was constructed containing osGP fragment (-197～-56) from the osRACD promoter with the minimal promoter,-90 region of CaMV 35S which confers Gus activity detectably only in roots. In the transgenic plants containing Cm1301, GUS activity was detected mostly in the anther.

由于35S基本启动子是一个根特异表达的启动子，因此将包含osDP5区段的osGP片段（-197～-56）与35S基本启动子连接，构成植物表达载体Cm-1301并转化烟草，研究发现，osGP区段使gus基因在雄蕊中表达水平显著提高。

Hardly less questionable is the view sometimes put forth, which identifies Habacuc with the Judean prophet of that name, who is described in the deuterocanonical fragment of Bel and the Dragon Dan., xiv, 32 sqq.

难以质疑的是，少的看法，有时提出的，其中确定了habacuc与犹太先知的名字，谁是描述在该次经片段对BEL和龙

The plasmid DNA of Streptomyces ahygroscopicus was extracted by soda split. The plasmid DNA was partial hydrolyzed by Sau3AI, and 3.5~9 kb DNA fragment was wllected by dialyze bag.

采用碱裂解法从不吸水链霉菌提取染色体DNA，用Sau3AI对染色体DNA进行部分水解，利用透析袋法回收3.5~9kb之间的DNA片段。

After the digestion by EcoR I/Sal I or Sal I/Hpa I respectively, the two digestional fragments were ligated with the digestional fragment of pMSCVneo by EcoR I/Hpa I.

构建乙肝缺陷病毒的工作虽然存在难度，但通过制备乙肝缺陷病毒治疗HBV感染的构想是可行的。

These data were used to infer the molecular formula and the elemental compositions of all the fragmental ions through software interpretation and, by further applying fragmentation regularities of mass spectrometry, the majority of ions were fully assigned. A base peak at m/z 402 in the mass spectrum was found as the molecular ion. The fragments were created mainly from the fragmentations of the tetrahydrofuran rings and the hydroxyl group. The most fragment products contain the dimethoxy phenyl group.

利用这些数据通过软件导出了分子式和所有碎片离子的元素组成，由此进一步根据质谱裂解规律对石梓醇分子的电子轰击质谱的主要裂解碎片给出了完全的归属，质谱中发现基峰为分子离子峰(m/z402)，裂解碎片主要来自双骈四氢呋喃环的裂解和羟基引起的裂解，绝大部分裂解产物包含二甲氧基苯基基团。

The linear plasmid and the designed fragment were directively ligated with T4 DNA ligase,and the plant expression vector of carrot afp was constructed.

将目的片段与线性质粒在T4 DNA连接酶的作用下进行定向连接，构建成胡萝卜afp的植物表达载体pBAF。

The amplified fragment length polymorphism technique was used to assess the genomic DNA polymorphism of four species Emberiza (cioides, leucocephala, tristrami and spodocephala). Eleven pairs out of thirty-nine AFLP primer pairs produced reproducible polymorphic DNA amplification patterns.

利用扩增片断长度多态性技术分析了鹀属4种鹀（三道眉草鹀Emberiza cioides，白头鹀Emberiza leucocephala，白眉鹀Emberiza tristrami，灰头鹀Emberiza spodocephala）基因组DNA的多态性。

The amplified fragment length polymorphism technique was used to assess the genomic DNA polymorphism of four species Emberiza (cioides, leucocephala, tristrami and spodocephala)Eleven pairs out of thirtynine AFLP primer pairs produced reproducible polymorphic DNA amplification patterns.

Col gene fragment of Engraulis japonicus of different geographical populations are amplified and sequenced.

本研究进一步对分布于黄、东海海域不同地理群体的鳀鱼mtDNA CoI基因片段进行了PCR扩增和测序。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
