The company has invested more than 6,000 million for dust transformation after transformation, ESP collection efficiency from 98% to 99.7% and reduce soot emissions by 3,000 tons / year;# 8,# 9 boiler flue gas desulphurization as a technical transformation project circular economy demonstration projects; invest in million-odd on-line monitoring system installed in flue gas to form an improved real-time closed-loop management.

该公司已投资改造后，粉尘改造6000多万美元，从3000吨ESP收集效率98％至99.7％，减少烟尘排放量/年；＃8，＃9锅炉烟气脱硫技术改造作为循环经济示范项目项目；百万元投资多在线监测系统安装烟气形成一个完善的实时闭环管理。

Circularization may facilitate recycling of translation factors and/or the ribosome, since ribosomes leaving the 3'end of the mRNA would be in close proximity to the 5'end for reinitiation.

环化可能有利于翻译因子和/或核糖体的循环利用，当核糖体从3'端离开后就处于5'端附近。

Some key techniques were analyzed and studied, which contains cross flow drying, switching forward and reverse airflow, on-line controlling of temperature and humidity of drying medium and circulating use of heat energy etc..

针对热风干燥水产品过程中常出现的表面干燥脱水过快、内部水分扩散通道易堵塞，造成产品水分不均匀度值较大，影响产品烘后品质问题，设计了专用U型隧道式水产品烘房，并对横流干燥、气流正反向切换、干燥介质温度及湿度在线控制、以及热能循环利用等关键技术进行了分析与研究。

Methods: Parallel-plate-flow-chamber was used to assay the influence of shear stress on endothelial cells morphology and cytoskeleton and apoptosis and NO secretion. endothelial cells morphology was observed under microscopy, cytoskeleton was showed by Coomassie brilliant blue staining, fluorescence stain, and transmission electron microscopy, apoptosis was detected by FCM, NO of circulating culture medium was assayed by NO kit.

细胞形态显微镜下直接观察；细胞骨架通过考马斯亮蓝染色、荧光标记和透射电镜进行观察；细胞凋亡通过流式细胞仪检测进行分析，一氧化氮通过流动循环培养基的收集后应用检测试剂盒进行检测分析。

The product was immiscible with the catalyst and could be separated simply by decantation after the reaction. As environmental benign catalysts, the TMPSHSO4 could be reused for nine times without noticeable lowering of catalytic activity.

结果表明，[HSO4]具有很高的催化活性，n(C6H8O7)：n(C4H9OH)=1：3.5时在125~130℃下反应3.0h，酯化率达到99%；反应结束后产物与催化体系分层，简化了分离过程；离子液体可以循环使用9次，催化活性无明显变化。

After 10 times reuse, the selectivity of the ester was still 100%.

循环使用10次后，芳香酯的选择性仍为100%。

This article built semi-dry FGD cold test platform, used the PIV technology to research field of velocity in the bed's base region.

本文搭建了半干法循环床烟气脱硫冷态试验台，采用PIV测试技术对文丘里后主床底部区域的速度场进行试验研究。

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。
