查询词典 migration

Electrokinetic transport process could promote effectively the desorption and migration of phenol and 2,4-dichlorophenol in soil; electromigration and electroosmosis were the main mechanisms; and the .

结果表明，电动力学过程能有效地促进土壤中苯酚及2，4-二氯酚的解吸附和迁移，电渗析和电迁移是其主要的作用机理，其迁移效果与电动力学形式、污染物类型、土壤酸碱性质和电极反应等密切相关，可以采用适当的电动力学工艺修复含酚类化合物的污染土壤。

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。

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。

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。

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。

Pachygyria is a neuronal migration disorder that develops during the 12th to 24th week of embryologic development, and results in various degrees of muscle spasm, hyperreflexia, seizures, developmental delay, and mental retardation.

巨脑回是一种神经移行障碍，发生于胚胎发育的12-24周，其导致不同程度的肌痉挛、反射亢进、癫痫发作、发育延迟和智力低下
