The results presented in this chapter have demonstrated the high performance of liquid transport by electroosmosis and the improved resolution by electrophoresis and shown a high potential of the electrochromatography on HAP.

本章所述的实验结果证实在羟基磷灰石色谱上施加电场所产生的电渗和电迁移有效地强化了分离过程的传质，从而提高了分离过程的速率和效率，该技术具有很大的发展潜力。

If a direct current electric field was applied to a polluted soil,the contamination would be motivated in a different way by the electroosmosis and electromigration.

当在土中施加直流电场时，污染物在电渗透和电迁移作用下向相反方向运动。

The relations of electrophoresis velocity, electroosmosis velocity and electric dispersion velocity are also investigated with these expressions. The results show that this new model offers a better explanation for peak compression effect on the migration behaviour of charged solute in CEC. The retention time will be shorter by peak compression effect, which is similar to a solvent gradients process. The peak compression effect is not steady, and doesn't appear until the conditions are fitted in some special situation.

基于弛豫理论所建立的基本模型，在考虑溶质在两相中皆有可能发生正、反向迁移的情况下，得到了流出曲线一阶原点矩和二阶中心矩的理论表达式，并通过对溶质在两相中电扩散速率与电泳速率、电渗流速率关系的分析结果证实：溶质在固定相表面的电扩散行为可以使其保留变弱，出峰加快；而这种电扩散导致的超常柱效峰的出现具有不稳定性，只有在多方面因素综合影响匹配的情况下才可能出现。

The content of CrO〓 and Cr〓 in electroplate waste liquid was determined successfully with this method.

经绘制标准曲线确定Cr、Cr的线性范围分别为0.5～35μg/mL和0.5～15μg/mL，迁移时间重现性的RSD均为0.9％(n＝7)，峰面积的RSD分别为3.1％和2.5％(n＝7)，测定的检测限分别为0.05μg/mL和0.04μg/mL，并将该方法用于电镀废液中铬离子的测定。

Results The longer time of exposure to the 150V/m electric field, the more electrotaxis the cells showed, that is, the distance of cellular migration increased obviously with the time of exposure to the electric field compared with control group.

结果 ①150V/m电场长时间作用下，培养的血管平滑肌细胞有明显的电场趋化性，细胞向负极迁移的距离明显高于无电场作用的对照组。

At its core, transformative learning theory is elegantly simple.

它的核心，迁移理论学极为简单。

The proposed improved genetic algorithm can achieve global search with migration and keep the best individual with elitism operation.

具有迁移作用的改良型基因演算法不但可以做到全域搜寻，还可以精英主义的概念取得最佳的个体。

Moreover the tensile stress and elongation at break keep at 45MPa and 100% respectively.

此外，CB的加入还有效抑制了共混体系中增塑剂的迁移和水蒸气透过率。

Based on the characteristics of biomass fuel, this article summarizes the sources of alkali metals in biomass and the elutriation and migration.

在明确了生物质燃料特点的基础上，对生物质中碱金属元素的来源和析出迁移规律进行了概述。

Concentrations of heavy metals in the suspended matter and sediment are not obviously affected by elutriation of stream and dilution of tributary stream. This feacture does not change even in the distant reach downstream. Therefore, the suspended matter and sediment are the potential source of heavy metal contamination to the waters for industry and agriculture use.

河流的地质、水文特征决定了河流悬浮物和沉积物成为河流中重金属搬运迁移的主要载体，在几十公里的下游水域中悬浮物和沉积物中重金属含量没有受到其它支流清澈水体的稀释，成为下游工、农业用水的潜在污染源。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
