Using 1,3-dicyanobenzene as a precursor, we have obtained two coordination polymer of rare earth metal bridged by isophthalato ligand, Eu complex (4) and Sm complexe coordinated (5). X-ray single crystal diffraction investigation confirms that complex 4 and 5 are isomorphous with near isostructural 〓 unit.

以1，3-苯二氰为前体，合成了两个新的稀土金属与间苯二甲酸根配体桥联的聚合物：间苯二甲酸根配体配合的铕和钐化合物，4和5.X-射线衍射结构分析表明化合物4和5均具有〓基本结构单元且两者结构类似。

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。

All patients have received bone healing. 12 cases showed bone healing 18-month later after X-ray inspection, the nail has been taken out and no fracture recur. the hip, knee extension and ankle brace, plantar flexion functions are good and normal walking is possible.

未发现主钉弯曲、锁钉脱出及断钉病例，开始负重时间为8～12周，平均9.1周，全部病例均获得骨性愈合。12例术后18月X线复查示骨性愈合，已取钉，无再发骨折，髋、膝关节伸屈及踝关节背伸、跖屈功能均好，行走正常。

Using high performance liquid chromatography, X-ray diffraction and Fourier transformation infrared spectra, the authors characterized the sorted proteins from different otoliths. It is found that the three types of proteins in lapillus and asteriscus have different characteristics, and such differences may be responsible for different kinds of crystalline state in calcium carbonate.

通过高效液相色谱、X射线衍射、红外光谱分析和氨基酸成分分析等方法分别对3种基质蛋白进行了表征，发现微耳石和星耳石中3种基质蛋白特征存在差异，并初步推断蛋白质特征的差别与碳酸钙晶体在微耳石和星耳石中的不同晶型有关。
