电动技术能够强化土壤物质的传质过程，能够高效、快速定向迁移土壤中重金属离子达到去除的目的；同时电动技术可以与其它修复技术结合发展出系列组合修复技术，具有广泛的应用前景。

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。

During the course of acid rain eluviation, Zn shows the most activation. Although Zn does not seem to be obviously anomaly, it has the highest concentration in soil solution and eluviation solution, the most activation heavy metal element in acid rain effect. Other elements including Hg, As, Cd, Cu, Pb etc.

已有大量研究结果表明，冲积平原区土壤中的Hg异常主要与Org.C有关，本次试验中又在土壤天然重砂中发现了辰砂矿物，Hg的上述存在形式特征决定了它在酸雨淋滤过程中的活动特性。3、酸雨作用下离子的迁移过程客观存在，这一点从土壤电导率研究结果中得到了确认。

The results indicate that the migration of heavy metal ions in soil is mainly dominated by the water flux density and distribution coefficients of the metal ions sorption to soil.

结果表明，金属离子在土壤中的迁移主要受水的通量密度和吸附分配系数的影响，并随时间的增加而增加。

The electron and hydronium in Silver halide minicrystal produce alternate independence repeat move,form develop center.

胶片感光乳剂层中的感光物质卤化银在受到光辐射后，产生光化学反应，卤化银微晶中的电子和离子发生交替独立的重复迁移，而形成显影中心，无数个显影中心，构成潜影。

The results show that the depletion layer grows in the form of hyperbolic tangent function of time, the electric field strength at the interface increases with bonding time to its maximum and the field strength in the bulk glass decreases, and that the fulfillment of the anodic bonding is determined by the completion of intimate contact rather than the charge transfer.

结果表明：碱金属离子耗尽层厚度以连接时间的双曲正切函数形式增长；界面电场强度随连接时间单调上升，而耗尽层外的玻璃内电场强度单调下降；电场辅助阳极连接是否完成决定于待连接表面间是否形成紧密接触，而非电荷迁移量是否达到某一恒定值。

Ionic bond A bond formed when an electron passes from one atom to another.

离子键：一种由于电子在两个原子间迁移而产生的键。

In this study, six surfactants with different ionic type, molecular structure, and phenanthrene (3-rings PAHs) were used to test the effects of surfactant to the degradation of phenanthrene, and to the combined toxicity with the phenanthrene.

本篇论文以六种不同离子类型、分子结构的表面活性剂和以菲为多环芳烃的代表，研究了表面活性剂对菲降解的影响，和与菲共存时的复合毒性，以及表面活性剂对菲在模拟生态系统中的迁移转化规律的影响。

The leaching of Na+ and Cl- is increasing with the increase of soil matric potential.

试验结果表明：垄作覆膜滴灌条件下各盐分离子的迁移和分布特性不同。

TOF-SIMS images show bacteriogenic pyrites are relatively rich in Cu, Zn, and Ni, suggesting that bacteria probably play an important role in the enrichment of Cu, Zn, and Ni during their formation.

TOF-SIMS 的离子像亦表明菌落成因的黄铁矿富集 Cu 、 Zn 和 Ni ，表明菌落在生物成因黄铁矿的形成过程中，在改变介质条件、在迁移、活化和富集 Cu 、 Zn 等金属元素方面做出了贡献。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
