反应器

Bioreactor is a kind of device intended for in vitro tissue culture that incubates the cells or tissues taken from living bodies in simulated physiological environment in vivo. On the basis of original cell culture, the present bioreactors apply biomechanical stimulation to simulate the stressed environment of articular cartilage in vivo.

生物反应器是一种体外的组织培养装置，它将活体内取出的细胞或组织在模拟体内生理环境下进行孵育培养使之生长分化，现有的生物反应器主要是在原有细胞培养的基础上加以力学刺激以模拟关节软骨在体内的应力环境。

As to these problems, a novel MBR named internal circulation membrane bioreactor is developed, in which the aeration not only supplies the required oxygen, but is utilized for the circulation of nitrified wastewater. It carries out the nitrogen and carbon removal of domestic wastewater in a single treatment unit. Simulated domestic wastewater is used in this research.

针对这些问题，本论文提出了一种新型的膜生物反应器——内循环式膜生物反应器，使曝气不仅为处理过程提供必需的溶解氧，而且实现脱氮过程中必要的混合液回流，实现了脱碳、脱氮过程在一个单体设备中完成。

The nitrogen removal experiment implies that the nitrogen removal efficiency is very high. The ratio of NH_4~--N/TN is approximately equal to the ratio of TN removal. TN removal efficiency is mainly affected by the influent NH_4~--N concentration, and the optimal TN removal efficiency can be prejudged by the ratio of influent NH_4~--N/TN.

通过对反应器的脱氮研究，发现该反应器的NH_4~--N去除率非常高，发现进水NH_4~--N／TN的百分比值基本上与总氮的去除率一致，脱氮的效果基本取决于进水氨的浓度，最佳的TN的去除效率能通过进水的NH_4~--N／TN比例来判断。

To start the reaction , water fills a priming chamber and solution chamber of the primary vessel , the priming chamber being located in an upper portion of the primary vessel , and an air pump forces a predetermined portion of water from the priming chamber via a feed line through a grommet at the top of the canister to a chemical reaction chamber of the canister along with a continuous air flow .

开始反应，水充满初级室和初级反应器溶液室，初级室是安装在1级反应器上部，并用空气泵驱驶水由初级室管道供给线通过罐子顶部的环眼并随连续的空气流进入罐子的化学反应室。

The results of continuous experiments with BAF show that: the short nitrification occurs when the Qair/Qinfluent ratio is 4:1 with NO_2~--N accounting for 72% of NOx--N; the suitable recirculation rate is 200%; the ratio of external acetate dose to NH4+-N concentration is 2:1 attributing to the short nitrification; BAF needs being backwashed when the headloss increases to 6 cm every 17~20 days; in the water reuse context, 98.7% water yield can be obtained.Lastly, the long-term operation of SBR-BAF system indicates it can treat the wastewater efficiently.

BAF反应器连续流试验结果表明：最佳气水比为4：1，硝化类型以短程硝化为主，NO_2~--N占到NOx--N的72%；综合考虑对TN的去除率和动力消耗，最佳回流比为200%；最佳缺氧/好氧容积比为3：5；由于短程反硝化较全程反硝化碳源需求量低，在BAF反应器进水NH4+-N 40mg/L左右的情况下，乙酸钠投加量为80mg/L以COD计设定水头损失达到6cm时进行反冲洗，随水温不同，反冲洗周期为17~20d，产水率为98.7%。

Trickle bed reactors are widely used as multiphase contactors in petroleum processing and chemical industry.

滴流床反应器是广泛使用的气-液-固三相反应器之一，在工业上有着广泛的应用。

Paper de- daces Lawrence-Mc carty model. The model explains theoretically relation be-tween mean retention period θc of cell.

从理论上说明了细胞平均停留时间θ、污泥负荷、反应器容积、反应器污泥浓度、出水浓度之间的关系。

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。
