The authors carried many researches of the feasibility about enriching and separating trace zinc from almost cadmium, and the rate of recoveries of several common metal ions according to this methodo Through repeatedly probed and tried out, at last, a thought as collaborated with traditional methods was established - using diantipyrinylmethane as complex reagent ,with ammonium thiocyanate and zinc forming the triple ionic compound in the medium of hydrochloric acid , extracted by trichloromethane, extracted the organic system by ammonium hydroxide in order to gain zinc .

本文主要研究了从镉基体中富集分离微量锌的可行性，以及采用该方法几种常见金属离子的回收率。通过反复的摸索、试验，最终确立了与传统方法相结合的思路—采用二安替比林甲烷作为络合剂和硫氰酸铵、锌在盐酸介质中形成三元离子缔合物，用三氯甲烷作为萃取剂，最后用氨水作为反萃剂将有机相中的锌洗脱出来与镉分离。

Ti〓 ion and triethanolamine may be combined together to form a complex which is dissolved in water at normal temperature.The hydrolysis of Ti〓 ion is controlled by the formation of the complex.

Ti〓离子和三乙醇胺可形成常温下较为稳定的水溶性络合物，从而避免了Ti〓离子的直接迅速水解。

In this study, nonionic surfactant sorbitan trioleate (Span 85) was modified with Cibacron Blue F-3GA to become an affinity surfactant (CB-Span 85) and to form affinity-based reversed micelles while dissolved in hexane. Since the CB molecule possesses a specific conformation that mimics nicotinamide adenine dinucleotide, it can bind strongly and specifically to a wide range of nucleotide-dependent enzymes such as dehydrogenases and kinases. Moreover, high protein transfer efficiency in the reverse micelles can be easily achieved by controlling the ionic strength of the aqueous phase.

本实验使用非离子型界面活性剂Span 85与蓝色染料分子Cibacron Blue F-3GA结合，形成具有亲和性的界面活性剂 CB-Span 85，由於CB染料分子具有与NAD+相似的结构，可与含核苷酸部位的蛋白质具有亲和力，将CB-Span 85溶於有机溶剂形成反微胞相，可有效的提高反微胞的选择率，可以只控制离子强度来调节蛋白质进出反微胞的效率。

And the chelation-enhanced fluorescence effect of tripodal naphthylethylamide derivative appeared when it was complexed with transition metal ions such as Cu〓 which have quenching potential.

其原因在于络合的过渡金属离子抑制了化合物的PET和化合物的三足结构又屏蔽了过渡金属离子对荧光体的直接猝灭作用。

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.

三脚架配体所带的羧基是一个很好的桥联基团，配合物的结构基元通过这种基团的桥联作用及其它一些弱的作用力(如氢键、π-π堆积作用等)联系起来，构成了一维、二维或三维的超分子空间结构。2、稀土配合物的发光研究发现：(1)用配体的π-π〓跃迁波长进行激发，配合物均显示出稀土离子的特征发射峰，同时，配体的荧光峰没有出现，这说明在三脚架配体与稀土离子间进行了有效的能量传递。

EDTA was used as masking agent, and trisodium citrate as total ion strength adjustment buffer was added to stabilize the ionic activity coefficient. The pH was controlled at about 5, the results were directly obtained by Gran graphing method.

以EDTA做掩蔽剂，加入柠檬酸三钠为总离子强度调节剂，使离子活度系数相对稳定，pH值控制在5左右，用Gran氏作图法直接查得结果。

Its principle is use feed pump to put the premixed material into the host milling barrel in which proper mill medium is addedand reasonable designed arc line style blades are installed on the main axis symmetrically.Explosion proof machine transits the energy used for separating and milling to main axis through static electricity proof V tape belt to drive blade rotate in high speed, thus it will offer mill medium with high intensity function which can drive beads do random motion and bump with separated grain to create strong cutting force and then cut the material into ion or dissociation,thereby the material will keep in permanent ultramicron separation state.

其原理是利用送料泵浦将预先已搅拌好的物料送入主机研磨桶内，研磨桶内加入适量的研磨介质，合理设计的弧线型葉片对称地安装在主轴上，防爆電机通过防静電V型皮带把分散和研磨所需的能量传送到主轴上带动分散葉片高速转动，给予研磨介质以高强度的动能，带动珠子无规则运动与被分散物料之颗粒撞击产生强大的剪切力，使物料变为离子或游离子从而达到永久的超细微粒分离状态。

The factors of temperature and humidity influenced on film thickness and order of layer were studied, in which pulling speed and pulling times were also included. It showed that the thickness of single dip-coating film reached 0.23 μm ~ 0.625 μm, and the degree of order of surface layer were still holding much higher.b Adopting calcined or uncalcined mesoporous silica membrane as matrix, nano zirconia particles were assembled through ion exchange method and ion-template exchange method.

结果表明，单次提拉膜膜厚0.23μm～0.625μm、8次提拉后表层膜仍有一定的有序性； b以自制的介孔氧化硅煅烧/未煅烧厚膜样为基体，采用离子交换法/离子模板交换法组装锆氧纳米粒子，选用DSC-TG、FT-IR、Uv-vis、SAXRD等对不同组装方法、锆源浓度、pH值等组装条件下ZrO_2/介孔氧化硅厚膜组装效果进行评价。

For fully annealed PE LiNbO〓 waveguide, only the absorption at 3484cm〓 is observed, whose half-height width is the same as that of unexchanged LiNbO〓(at 3484cm〓).

利用离子扩散理论分析了PE Fe∶LiNbO〓波导中H〓和Li〓的分布及退火的影响；由离子热扩散的缺陷模型得到热还原Fe∶LiNbO〓中Fe的偏折方程。

Micro-hardness and fretting wear of the implanted samples were measured and compared to the unimplanted substrate.

这主要归因於离子注入造成的表面强化，以及离子注入在基体表面产生的压应力。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
