The change of average size of products along the radius at the exist of reactor has also been calculated. The calculated results indicate that the residence time is longer, the average size of products is larger, but the distribution of size is narrower, tending to self-preserving distribution; when the concentrations of reactants increase, the average size of products becomes larger, but the distribution of size becomes narrower; the gradients of reactants are greater, the average size is larger; the increasing of reacting temperature will cause the size of product to be larger under same residence time. The average size of product at the exist of reactor varies along the radius, has a maxim value.

模型计算结果表明，产物粒度随停留时间的增加而增大，但粒度分布变窄，趋向自保分布；产物粒度随反应物进料浓度的增加而增大，粒度分布随进料浓度的增大而减小；反应器中反应物浓度梯度较大（相当于化学反应为快反应）时，相同停留时间下所得到的产物平均粒度增加；反应温度的增加，粒子平均粒径增加，粒度分布变窄；反应器出口处粒子平均粒径，随着与对称轴的距离的增加，有一极大值，先增加，后减小。

Based on limiting the tensile strain at the bottom of the asphalt layer and the vertical compressive strain at the top of the subgrade, the suitability of layer thickness is checked by two criteria. One is controlling the maximum surface deflection under the design load, and the other is controlling the modulus ratio between adjacent unbound aggregate base and subbase layer.

该方法基于限制沥青层底的拉应变和路基顶面的压应变，采用两个准则来校核所设计的沥青层厚度的适宜性：一是控制设计荷载作用下的最大路表弯沉；二是控制相邻两个无结合料处治的集料层的模量比。

The type, initial feeding time and concentration of precursor for HV unit formation had great effects on PHBV production in shake flasks. Propionate was selected as the better precursor for HV fraction than valerate after comprehensive survey of these two precursors. The suitable PHBV shaking-flask culture conditions were obtained through the analysis of PHBV fermentation process, the investigation of several factors by using RSA method and the fed-batch experiments. Cell dry weight, PHBV content, PHBV concentration, HV fraction and yield coefficient of HV unit to propionate were 27. 7g/L, 80.7%, 22. 4g/L, 16. 1mol% and 0.50g/g, respectively.

在共聚物PHBV的摇瓶发酵过程中，PHBV中HV组分形成的前体物质的种类、初始加入时间以及加入量是影响PHBV发酵过程的重要因素；在综合比较丙酸和戊酸这两种前体的基础上，选择丙酸作为HV组分合成前体较适宜；通过对PHBV发酵过程曲线分析、影响PHBV发酵指标的各因素的响应面分析以及摇瓶发酵补料试验，得到了较适宜的PHBV摇瓶发酵补料条件，在此条件下，细胞干重、PHBV含量、PHBV浓度、HV组分含量和HV组分对丙酸的产率系数可分别达到27.7g/L、80.7％、22.4g/L、16.1mo1％和

Two mathematical models have been deduced in the case of dense-phase and light-phase conveying respectively. Combining the capacitance phase concentration sensor designed and the traditional Venturi flow meter, the powder velocity and instantaneous mass flowrate are obtained by measuring concentration and differential pressure signal.

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。
