Various [BO6] units exhibit remarkable differece in stability, ion size and ion electrovalence. Therefore, the growth interfaces with electric charges would make a choice among those [BO6]growth units, resulting in the short range of fluctuation in composition and structure at the stage of crystal growth and preparing for the aubsequent formation of ordered domains and other chemical defect clusters.

在基元组装过程中，各种[BO6]八面体基元在稳定性、尺寸大小与电价上的分异致使生长界面对基元有一定的选择性，从而造成了晶体生长时成分与结构的短程起伏，并为有序畴及其它化学缺陷团簇的形成提供了条件。

Cr6+ treatment method for eluate of ion exchange resin column in treatment of plating waste water contaning chromium with ion exchange method was introduced.

A new type of electrolysis separating device is designed to solve the problem in treating plating sewage by ion exchange technique. With electric current efficiency being up to 80.5%, it could effectively separate acid or alkali from ion exchange eluate.

针对离子交换技术处理电镀废水所存在的问题，提出了一种新型的电解装置，它能将离子交换洗脱液中的酸／碱有效地分离出来，电流效率高达83.5%。

ZO1 and Cx26 expressions in the sensory epithelium have different location and were not overlapped. Tight junctions maintain the ion barrier between the endolymph and perilymph,and gap junctions take part in ion transportation.

Cx26和Cx30分布在基底膜的各种支持细胞，在感觉毛细胞没有表达；此外，该研究发现Cx26和ZO1在耳蜗内具有不同的表达方式和表达部位，紧密连接ZO1在网状板面构成了毛细胞之间或与其支持细胞之间的离子屏障，阻止内、外淋巴之间的相互流通，保持了各自之间的离子平衡；缝隙连接则表达在基底膜的深层，参与离子转运。

To control the film growth,severalmethods based on energetic particle(atom and/or ion)depositions,e.g.,ion beam assisteddeposition,sputter deposition,accelerated molecular beam epitaxy,and energy-filtered ionbeam deposition,etc.,were developed in the past few years.
