All the compounds are characterized by IR and elemental analysis.we design and prepare a bipyridinium supramolecular compound and six coordination compounds, which are also characterized by IR, elemental analysis and X-ray structure analysis. According to X-ray structure analysis, hydrogen bonds and n-n stocking interactions participate in the architecture of three-dimensional framework [H2L1 (NO3)2 (H2O)2]n; one-dimensional zigzag coordination polymer [Hgl21.5CH3OH]n; binuclear metallamacrocycle (HgI2L2)2 3H2O; helical double-stranded one-dimensional coordination polymer [Co2(L2)2-2CH3OH]n; double-stranded one-dimensional coordination polymer [Co2(L3)2-CH3OH-CH3CN]n; and three-dimensional compound [Cu(C5H4NCOO)2(H2O)2]-H2O with hydrogen bonds, three-dimensional coordination polymer {[Cd(C5H6NCOO)2H2O]-DMF}n, which are indirectly obtained from the precursor ligand L3 through metal ion induced the hydrolysis of diamide and self-assembled with the hydrolyzate.

此外， 在镀液离子低浓度范围内，及Cu/In离子浓度比不变的前提下，镀液中金属离子总浓度的改变不会影响镀层的成分和形貌；十二烷基硫酸钠和苯亚磺酸钠可作为理想的辅助添加剂，能改善薄膜形貌，使其表面均匀、规整。

They were recovered f rom the ion exchange bed by dilute HCl and , final2 ly , were replaced in the spent HCl by Al to form valuable water t reatment coagulant and recycleable metals.

Negative radial electric field always associate with edge ion loss or separation of ions and electrons in same layer.

通过大量分析各种装置H-模的产生条件及其差异性，诸如装置磁场位形、等离子体与壁或限制器的间隙、第一壁条件、离子梯度磁场和曲率漂移方向等因素，研究它们与负径向电场或者说与边界离子损失的关系，认为在环形磁约束装置中电子基本上沿磁力线或磁面运动，而离子由于受梯度磁场和曲率漂移的影响大，有横越磁面的运动分量，会产生相对于磁面的扩张轨迹和压缩轨迹。

During ion source operating, alternating axial magnetic field and azimuthal electric field in discharge tube ionize hydrogen gas purified by hot palladium pipe, and form plasma. In fifties year, research reports studied on RF ion source are numerous however most of them are concerned about application, and research reports relevant to discharge theory or experiment model are unfrequent.

离子源工作时，放电空间交变的轴向磁场和涡漩电场激发放电管中经钯管纯化后通入的氢气电离，形成等离子体。50多年来，关于高频离子源的研究报告很多，但是，这些研究主要都集中在应用研究方面，有关高频无极环形放电离子源的理论与实验模型研究不是很多。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
