中心体

The crystal consists of two similar but independent molecules in the asymmetric unit and the Ce ion coordinated toward ten donor atoms, six of which belong to the nitrogen atoms of two tridentate ligands and four oxygen atoms from two bidentate picrates.

晶体中一个不对称单元内有两个结晶学上独立的分子，这两个分子的构型基本相同，中心Ce3＋均与两个三齿配位的配体及两个双齿配位的苦味酸根配位，配位数为10。

With two tripodal ligands, dtma and tmpa, dtma=diethylenetriamine-N'-acetate and tmpa=tris(2-pyridyl-methylamine and a polyamine ligand, trien (=triethylenetetramine), serving as terminal ligands, we synthesized 19 species of new imidazolate -bridged Cu-Zn, Zn-Zn and Cu-Cu, and other relating compounds, in which 〓 and 〓 complexes are model compounds of Cu, Zn-SOD.

用不等臂三脚架dtma(diethylenetriamine-N'-acetate)、直链trien和等臂三脚架tmpatris(2-pyridyl-methyl-amine为配体，合成了一系列咪唑桥联Cu-Zn、Zn-Zn和Cu-Cu等有关19个新化合物，其中两个异双核〓Cu〓和〓〓配合物为Cu，Zn-SOD活性中心的模型化合物。2。

The pore structure types are fine throat-small pore and micro-fine throat-small pore. The reservoir shows stronger unhomogeneity in the study area.

储层非均质性明显，物性总特征为平面上砂体中心部位良好，部分井点由于次生孔隙发育，孔隙度、渗透率、含油饱和度变好。

Mn(H_3biim)_2_2Cl_2 and Cd(H_3biim)_2_2Cl_2 have been synthesized from H_2biim, their structures were determined by X-ray crystallography. The two complexes have similar structures and both are neutral compounds. One N atom in H_2biim is protonated, forming a H3biim+ cation. The later is an unidentate ligand, the central metal, Cd or Mn is six coordinated and adopts a distorted octahedral environment.

合成了联咪唑锰配合物Mn(H_3biim)_2_2Cl_2和联咪唑镉配合物Cd(H_3biim)_2_2Cl_2，晶体结构表明这两个配合物结构相似，均为中性化合物，联咪唑的一个氮原子被质子化，形成一价阳离子(H_3biim~+)，它采取单齿配位，中心Mn原子是六配位，其配位环境为畸变的八面体。

Objective To evaluate the clinical value of removal of central uterine body.

It's interesting to look at the wildly divergent list of winners at the annual Webby Awards─everything from Google Earth to the Katrina Help Center to the Sherwin-Williams Color Visualizer─and realize the web is still figuring out its standards.

看着年度威比奖得主来自各行各业──从「谷歌地球」、「卡翠娜飓风赈灾中心」到「史韵──威廉斯色彩想像软体」不一而足，并领悟到网际网路仍在设法寻找他们的标准，实在很有意思。

Methods: Thirty-five sets of normal adult dry cervical vertebrae and 100 sets of X-ray and CT films were measured, including pedicle width, height, length, projection, pedicle-body angle, lateral mass width, height, thickness, the distance and angle between the central point on the back wall of the lateral mass and the foramina transverse foramen, the supra articular process-body angle.

对35套正常成人颈椎干燥骨标本以及100套X线片和CT片进行测量，包括椎弓根宽度、高度、长度、投影点位置、与椎体的夹角、侧块宽度、高度、厚度、后壁中心点与横突孔的距离和夹角、上关节突的倾角等。

With the fast development of international electronics industry, as main base body materials, 7628 cloth will appear good development trend, meanwhile, world electronic center will turn to the Asian-Pacific area from Europe and cause to electron grade of glass fibre cloth in short supply within quite a long time too.

随着国际电子工业的快速发展，作为其主要基体材料的7628布也必然会呈现出良好的发展趋势，同时，世界电子中心将从欧洲转向亚太地区，也必将导致电子级玻璃纤维布在相当长的时间内供不应求。

However, discussions are still about Hanfu characteristics,given the evolution of such areas as body-centered,perspective is also more focused on the analysis from a literary point of view.

不过，仍以讨论汉赋特征、赋体演进等方面为中心，视角也多集中于从文学角度进行分析。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.

深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
