Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。

Even without any sign of war, recent months have seen a number of countries either ban, or attempt to tax, food exports in an attempt to safeguard supplies for the local population.

最近几个月并没有任何发生战争的迹象，但仍有许多国家对粮食出口实施了禁止或课税措施，以保证对本国人口的粮食供应。

In most states each attorney is allowed to reject a minimal number of potential jurors without giving a reason.

在大多数国家代理人有权在不说明原因的情况下拒绝极少部分有资格的陪审员。

It's impossible to access any of the rooms off this corridor without a key card and PIN number.

The high bandwidth and large number of sub-carriers used for DVB-T and DVB-H allow for the reduction of several kilohertz of spectrum around DC without noticeably degrading performance.

高宽带和大量子载波频率的使用，使 DVB-T 和 DVB-H 在直流电中允许数千赫兹的缩减，而没有显著的不良表现。

The most that can be said for Infosys's programme—without devaluing Mr Sadagopan's efforts—is that it is a great opportunity for a tiny number of middle-class Indians, who happen also to be low-caste.

最值得一提的可能是， Infosys 公司的这一计划恰是印度数量微小的中产阶级的一个极好的机会，因为他们碰巧也属于低种姓的一员——这并非贬低 Sadagopan 的努力。

The case for rejoicing in the increasing number of women who enter the learned professions has nothing primarily to do with providing them with gainful employment or giving them an opportunity to develop their full potential. It is above all due to the fact that the world is now such a complicated and rapidly changing place that it cannot even be kept going (let along improved, as we meliorists think it can be) without using the intelligence and skill of approximately 50 percent of the human race.

如今越来越多的女性进入学术领域，这一令人欣喜的现象最重要的原因并不是社会要给女性提供有利可图的职位或给她们全面发展自己潜能的机会，最重要的原因是：社会如今如此复杂，发展如此迅速，如果我们继续浪费约占人类智慧和才能50%的那些资源，我们的社会就很难正常运行，更别说发展了。

我司把握市场机遇，自行生产多款无支架雨刷，深受市场好评。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
