We successfully improved the methods of departing O-methyl using boron tribromide, of isolating hydrogen bromide byα-chloro-ethyl chloroformate, and of related in synthesis of natrexone, new medicine, using boron tribromide. This resulted in generation of hydrogen cyanide becoming impossible.

改进了以氯甲酸-α-氯乙酯脱代替溴化氰以及改进的三溴化硼法作为新药纳曲酮合成中相应的方法，去除了合成过程中产生氰化氢气体的可能性。

Because of no signal from N-terminal protein sequencing for 43kDa protein directly, a resulting 18kDa peptide from the partial cleavage of 43kDa protein by BrCN had its N-terminal sequences of AFTFKK determined by N-terminal protein sequencing assay. Then, the 43kDa protein was convinced to the enzyme of 3phosphate glycerate kinase (PGK1) by searching YPD.

由于43kDa蛋白直接进行蛋白质氨基端序列测定时没有信号，因而用溴化氰部分化学裂解43kDa蛋白，得到的18 kDa多肽经蛋白质氨基端序列测定，得到其氨基端前6个氨基酸残基序列为AFTFKK，通过计算机检索YPD，确定43 kDa蛋白是3—磷酸甘油酸激酶（PGK1）。

The present invention uses isocyanuric acid as main raw material, and adopts the following main steps: adding alkali to make solvation, chlorization, bromation, secondary chlorization, filtering and drying to prepare bromochloro-isocyanuric acid.

本发明公开了一种溴氯异氰尿酸消毒灭菌剂的制备方法。该方法以异氰尿酸为主要原料，通过加碱溶解、氯化、溴化、再氯化、过滤、干燥主要步骤制备溴氯异氰尿酸。

Methods Activate groups A and C meningococcal polysaccharide with cyanogens bromide and prepare into MenAPS-ADH and MenCPS-ADH derivatives by reacting with 1, 6-adipic acid dihydrazine. Mix MenAPS-ADH and MenCPS-ADH derivatives with purified tetanus toxoid at a certain mass ratio, then add l-ethyl-3(3-dimethylaminopropyl)-carbodiimide to prepare bulks of MenAPS-TT and MenCPS-TT conjugates respectively. Mix the two bulks at a certain ratio, add stabilizer and lyophilize to prepare group A+C meningococcal polysaccharide conjugate vaccine.

We verified the purification procedure by SDS-PAGE and Western blot. Their interactions were investigated by using Far-Western blot and Pull-down assay.

通过葡萄球菌V8蛋白酶和溴化氰对P4.2蛋白的限制性酶切分析，我们选取了一系列序列重叠的P4.2片段进行克隆表达。

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。
