迁移的

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。

Little amounts of cyanide were found in all parts of plant tissues, indicating the passage of ferrocyanide through the plants.Mass balance studies showed that iron cyanide complex moving into plants from hydroponic solution can be metabolized during transport.

由于没有检测到在气态下的总氰化物，表明植物的蒸腾作用没有将亚铁氰化物释放到大气中；(3)尽管植物吸收到体内的亚铁氰化物足有限的，但物质平衡实验表明其在植物体内迁移的过程中超过96％的郜能被植物有效转化；(4)所用的4种亚铁氰化物浓度在192 h内没有对柳树产生毒性作用。

Mass balance studies showed that iron cyanide complex moving into plants from hydroponic solution can be metabolized during transport. Phytotoxic effects were not found in all treatment groups, even at high doses of ferrocyanide within a 192-h exposure period.

This review introduced the study of cell cycle of male and female gametes before fertilization; discussed the question of synergid degeneration; analysed status of research into the movement of both sperm cells in degenerated synergid; and evaluated the preferential fertilization of sperm cells and the egg cell activation of angiosperms.

本文介绍了目前被子植物精、卵细胞融合前后的细胞周期变化、退化助细胞的功能、精细胞在退化助细胞中迁移的研究动态、精细胞的倾向受精和卵细胞的激活等被子植物受精生物学领域中的一些新的研究成果和发展趋势。

According to the distribution of the positive charges inthe surface of the cage, it can be expected that two -OH groups finally adding at two sites which arewithin one hexacyclic ring and in different sides of equator, which is accord with the conclusion resultedfrom thermodynamics

通过寻找并分析过度态的结构，发现酸化阳离子中处于赤道带6-6类碳原子上的羟基和两极区域5-5类碳原子上的羟基都有朝邻近赤道带碳原子上迁移的可能，结合碳笼上正电荷的分布特征，预计亲核水解作用将发生在赤道异侧六员环的对位，说明考虑动力学因素，最终获得1，4-加成富勒醇的可能性最大，该结论与热力学的结果一致。

By self-explanation strategy, we can teach experimental subjects how to study and use examples in learning to solve physics problems, so metacognitive monitoring explanation strategy is a more well-advised means of physics learning than practice strategy, and the learning transfer level of subjects are also higher.?

实验结果表明：①以揭发意义或价值，建立新旧知识信息间实质性联结的解释策略对高知组和低知组的被试都具有明显促进物理问题解决的作用；以相似性、类比为依托的练习策略在学生头脑中建立的只是新旧知识间表面特征的联结，因而学习迁移的效果不如前者。

The numerical solution of carbon diffusion was solved and the finite difference method was used, the inner boundary conditions of the meshes were treated using diffusional flux and carbon's activity, and adaptive software was assembled. The system of identification indicated that the numerical results were accordant to the expermental results.
