Drug intervention groups received either daily inhalation of budesonide, ipratropine or heparin respectively, starting on the 8th day or TGF-β1 monoclonal antibody(TB21)0.5 mg twice (6th and 19th day) via the tail veinous injection.

其它各药物干预组于制作模型第8 d起分别雾化吸入布地奈德（布地奈德组，12只）、溴化异丙托品（溴化异丙托品组，12只）和肝素（肝素组，6只）溶液。4周后检测小支气管平滑肌及胶原厚度，用免疫组化法及原位杂交法观察各生长因子在支气管肺内的表达，用放免法检测血清和BALF中细胞外基质成分Ⅲ型前胶原、层粘连蛋白及透明质酸。

Results:The results showed that the apoptosis of neutrophiles was promoted by the treatment of 1 μg/ml LPS and 1 μm A23187,in 6 hours and 12 hours respectively.The apoptosis of neutrophil was markedly delayed by a PLA2 inhibitor,4-bromophanacyl bromid (p-BPB 0.01～1 mM).

结果：脂多糖（LPS 1μg/ml）和钙离子载体（A23187 1 μmol/L）等PLA2激动剂分别在共同培养6 h和12 h之内促进中性粒细胞凋亡，而PLA2阻断剂4-溴苯甲酰溴甲烷(p-BPB 0.01～1 mmol/L)可明显减弱上述激动剂的促凋亡作用。

One-step synthesis of the high molecular weight bromated epoxy resins for flame retardants is studied with tetrabromobisphenol A and epichlorohydrin as raw materials in mixed solvent comprising 1,4-dioxan and water.

研究以四溴双酚A和环氧氯丙烷为原料在二氧六环和水混合溶剂中一步法合成了高分子量溴化环氧树脂阻燃剂。

One subject of the present work relates to a green chemistry synthesis of tetrabromobisphenol A wherein the combination of sodium bromide and sodium bromated as brominating agent which completely replaces conventional liquid bromine.

据文献报道，该产品在某些阻燃材料中将是十溴二苯醚的理想替代品之一，目前，仅有国外公司在销售该种产品，我国还没有实现真正的工业化生产，所以研制开发溴化环氧树脂阻燃剂具有重要意义，本文研究工作主要包括三方面的内容。

A chemical or chemicals viewed from the perspective of their structural characteristics. Included here are concepts which can mean either a salt, an ion, or a compound (e.g.,"Bromates" and "Bromides").

根据其结构特性划分的一种或一类化学物质，包括某种盐，某种离子或某种化合物，如溴酸盐及溴化物。

Bromofluorene were obtained by bromating fluorene.

以芴为原料，通过溴化得到9-溴芴。

On the base of the results, a new synthetic route of brominated Q0 was reported. The method was more favorable for the preparation of Q0, and the yield was above 86%.

在此基础上，研究了溴化Q0的合成方法，形成了一条新的、简便的溴化Q0的合成路线，收率达86%以上。

Meanwhile, the exploitation and application of the brominated flame retardants products and the technologies in the flame retardants system were introduced.

阐述了溴系阻燃剂的特点和阻燃机理，重点介绍了阻燃体系中溴系阻燃剂产品及阻燃技术的开发与应用。

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。
