The title complexes both have the well-known α-Keggin structure, based on a central PO_4 (GeO_4) tetrahedron surrounded by 12 MoO_6 octahedra arrayed in four groups of three edge-shared MO_3O_(13) octahedra.

标题化合物具有大家熟悉的α-Keggin结构，中心由PO_4(GeO_4)四面体周围有12个MoO_6八面体分成四组排列，每三个共边组成Mo_3O_(13)簇。

In addition, the relationship between the structure and the third-order nonlinear properties of this complex is discussed.

探讨了配合物的结构和其三阶非线性光学性质的关系，认为配位化合物的丌共轭离域体系的增大和金属中心离子与配体之间的电子转移是配合物具有更大非线性折射率的主要原因。

Brief: the program offers water tour around Haiquan Bay, exploration on out-lying islands; world hot spring cultural tour, and heath care center experience.

简介：活动包括水上畅游海泉湾、神秘岛探险、寻找遗落在《海边的梦》、世界温泉文化之旅和康体中心，生命加油站感悟等。

Quantitative analysis of the EXAFS spectra showed that the microscopic structure of Znon anatase TiO2 is four coordinate complex, and there are at least two types of bonding based on the average Ti-Zn distances in the second sphere. Two different geometry configurations of single-corner and double-corner for adsorption on the (101) surface cluster were calculated using DFT method.

EXAFS结果表明，Zn在吸附时由自由水合状态下的Zn-O六配位八面体结构向四配位四面体结构转化，中心Zn原子的第二配位层存在两种不同的Zn-Ti距离（R1=0.371和R2=0.332nm）。

According to successfully extracting and graphing of uranium anomalies, the self-center uranium anomalies and their close relationship with meandering stream systems have been observed. The uranium anomaly always develops in the distributary and turning place of meandering stream system, and is related with thin sand area (whose sand thickness and sand ratio are less than 30 meters and 40% respectively), thicker coal, fine lithology, but the highest value of uranium anomaly exists in middle sandstone.

通过对铀异常信息的成功提取及平面编图，发现延安组中铀异常呈一个又一个具有自我中心的单元出现，且与曲流河沉积体系的关系密切：通常发育于河道分岔或转弯处；普遍发育于薄砂带，一般砂体厚度在30m以下，含砂率小于40%；铀异常单元与厚煤层关系密切；主要赋存于粒度较细的岩性中，部分也富集于煤中，但铀异常最高值富集于中砂岩中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
