The influence of coordination environment on the luminescence property and intramolecular energy transfer of complexes were discussed.

讨论了配位环境对荧光性质的影响以及配合物分子内能量传递问题。

We also studied the influence of metal ion on the structure of complex.

我们研究了金属离子的性质对配位化合物结构的影响。

By means of X-ray diffraction, nitrogen adsorption, UV-Vis diffuse reflectance, a successful isomorphous substitution of titanium in the silica framework of SBA-15 samples with Si/Ti = 50, 25, 20 has been proved, the substitution of Ti for Si does not change the highly ordered two-dimensional hexagonal mesostructure of SBA-15. Titanium is totally tetrahedral and highly dispersed.

通过X射线衍射、N2气吸附脱附、紫外—可见漫反射等表征手段，证明在Si/Ti＝50，25，20时，钛原子成功地取代了SBA-15中的硅原子而没有改变SBA-15高度有序的介孔二维六角结构，其中钛全部以四配位状态存在，而且高度分散。

The work may offer new insight to the mechanisms of the biological effects of lanthanides.

其原因可能在于模拟细胞环境的复杂性以及CaM-CaMBP蛋白质相互作用对金属离子与CaM配位结合的调节。

The coordination chemistry of lanthanides has been of increasing significance due to the wide use of lanthanide complexes in luminescent probe, supramolecular device or MRI contrast agent.

由于稀土光致发光配合物在荧光探针、超分子器件及核磁造影剂等方面的广泛用途，对稀土配位化学的研究日益重要。

The induced supramolecular chirality was found to be dependent on the absolute configuration of lateral residues, that is, the polymers with-configurational oxazolinyl chromophores tended to form chiral aggregates with levorotatory handedness, while polymers obtained from the-monomer offered dextrogyrate one upon the addition of Cu salt. A model, in which side groups would arrange in a helix fashion, is employed for describing the unusual chirality.

由此提出了侧基在Zn／Cu协同配位作用下形成螺旋状排列的模型，即侧基螺旋模型。N-噁唑啉苯基马来酰亚胺与甲基丙烯酸甲酯共聚得到了耐热性能好(热分解温度大于296℃)的光学活性聚合物~(25D=-7.8°(来源：Af4BC论文网www.abclunwen.com)～-36.6°。

Parameter n of Freundlich isotherm equation greater than unity describes Lutetium adsorption on peat by Lutetium-peat 1:1complex and rapid adsorption on peat.

Freundlich吸附等温方程中的n值大于1，说明镥在泥煤上的吸附以单配位为主，且该吸附容易进行。

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。
