采用干粉叠层法和热压工艺制备HA／316L不锈钢对称功能梯度生物复合材料，使用三点弯曲法测定HA／316L不锈钢对称功能梯度生物复合材料试样的抗弯强度和弹性模量，并借助扫描电子显微镜对试样对表面形貌和微观结构进行观察和表征，利用场发射高分辨扫描电子显微镜对试样进行元素线扫描分析。研究结果表明：通过控制HA粉末的含量（体积分数）在20％-40％之间时，所得复合材料的抗弯强度和弹性模量分别与人体骨的强度和模量相匹配，得到生物力学相容性好的复合材料；HA／316L不锈钢复合材料各梯度层之间过渡自然，没有明显的宏观界面、缺陷和裂纹等，梯度层内部和界面处两相分布均匀，且各成分均呈现连续的梯度分布，界面结合紧密。

用骨粉和聚-L-乳酸复合制得骨粉/PLLA内固定复合材料,研究骨粉加入量对复合材料的力学性能的影响,对骨粉进行粒度分析和红外光谱分析,对制得的复合材料进行XRD和SEM表征。研究结果表明:所用骨粉为超微米级颗粒,可为其与聚-L-乳酸基体材料提供很大的接触面积,增加复合材料的力学性能;脱脂脱蛋白皮质骨粉主要含有羟基磷灰石,大量的蛋白质等有机化合物均被除去;由于骨粉的加入使复合材料的结晶度和抗弯强度有所降低,而弹性模量有所升高,不同含量骨粉的复合材料的抗弯断口形貌也发生了变化;所得骨粉/PLLA复合材料具有良好的生物活性,是骨科内固定器件中的理想可降解生物材料。

通过溶液沉析纺丝法制备聚丙交酯乙交酯(PLGA)纤维,观察纤维的形貌并对其进行XRD和SEM表征。采用纤维温压成形法控制压力和温度得到条形的PLGA材料结合试样断口分析,研究成型压力与温度对PLGA材料的力学性能的影响。研究结果表明:非晶多孔结构的PLGA纤维可通过溶液沉析纺丝的方法获得,其孔径为0.1～1.0μm;压制压力和压制温度对材料的力学性能影响较大,材料的抗弯强度、剪切强度和抗弯模量均随着温度和压力的增大而先增大后降低;在压制压力为105MPa,压制温度为160℃时,试样的力学性能比较理想,此时,其抗弯强度可达到187.3MPa,剪切强度达到100.1MPa,抗弯模量达到2.5GPa,可望作为非承重部位骨折愈合内固定材料。

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

INTRODUCTIONThe prevalence of hyperuricenlia （HUA） has increased in China in the recent years in relation to socioeconomic developments and changing lifestyles and diets, with a trend toward onset at younger age. HUA has become the second most common metabolic disease after diabetes mellitus. Like gout, HUA is also associated with the occurrence and progression of disorders of the urinary, endocrine, metabolic, cardio-cerebrovascular, and other systems.
