Correlations of active galactic nuclei （AGNs） with microquasars are discussed based on the coexistence of the Blandford-Znajek （BZ） and magnetic coupling （MC） processes （CEBZMC） in black hole （BH） accretion disk. The proportions of several quantities of BH systems for both AGNs and microquasars are derived by combining the observational data with CEBZMC. It is shown that the square of the magnetic field at the BH horizon is inversely proportional to the BH mass, while the accretion rate of the disk is proportional to the BH mass. In addition, the very steep emissivity indexes from the recent XMM-Newton observations of the nearby bright Seyfert 1 galaxy MCG-6-30-15 and the microquasars XTE J1650-500 are well fitted by considering the MC effects on the disk radiation. These results suggest strongly the correlations of A GNs with microquasars.

Since 1995,bulk-heterojunction organic solar cells consisting of one or two organic donors and one or two organic acceptors have been fighting for high power conversion efficiencies(PCEs)and good stability[1].Until recent years,this next-generation photovoltaic technology starts to offer decent PCEs,shedding the light on commercialization,and attracting great attention again[2-14].Compared w让h the continuously emerging highperformance nonfullerene acceptors,high-performance donors are rare.

The Lijiang 2.4-meter Telescope(LJT), the largest common-purpose optical telescope in China,has been available to the worldwide astronomical community since 2008. It is located at the Gaomeigu site,Lijiang Observatory(LJO), in the southwest of China. The site has very good observational *** its 10-year operation, several instruments have been equipped on the LJT. Astronomers can perform both photometric and spectral observations. The main scientific goals of LJT include recording photometric and spectral evolution of supernovae, reverberation mapping of active galactic nuclei, investigating the physical properties of binary stars and near-earth objects(comets and asteroids), and identification of exoplanets and all kinds of transients. Until now, the masses of 41 high accretion rate black holes have been measured, and more than 168 supernovae have been identified by the LJT. More than 190 papers related to the LJT have been published. In this paper, the general observation conditions of the Gaomeigu site is introduced at first. Then, the structure of the LJT is described in detail, including the optical, mechanical, motion and control system. The specification of all the instruments and some detailed parameters of the YFOSC is also presented. Finally, some important scientific results and future expectations are summarized.

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.

目的：总结分析儿童肌病性高肌酸激酶（creatine kinase,CK）血症的病因和临床特点,探讨在不同肌病中CK及其他肌酶如乳酸脱氢酶（lactic dehydrogenase,LDH）、天冬氨酸氨基转移酶（aspartate aminotransferase,AST）升高的程度.方法：收集2004年1月至2011年12月北京大学第一医院儿科门诊和住院的235例确诊为各类肌病并且生化检查提示CK增高的患者的临床资料进行综合分析,进一步按病因予以回顾性分析.结果：235例患儿中男180例,女55例,发现CK增高时患儿年龄〈6个月者64例,6个月至3岁者90例,3～6岁者50例,6～14岁者31例; CK显著增高者162例,中度增高者31例,轻度增高者42例.发现CK增高的年龄和CK增高的程度与肌无力症状的严重程度无明确相关性,多数表现为慢性高CK血症,CK值由高至低依次为：Duchenne肌营养不良（Duchenne muscular dystrophy,DMD）＞炎症性肌病＞先天性肌营养不良（congenital muscular dystrophy,CMD）＞代谢性肌病,LDH和AST值依次为：DMD＞炎症性肌病＞代谢性肌病＞CMD,其中代谢性肌病中LDH升高相对较为突出.结论：儿童肌病性高CK血症的病因不同于成人,肌病性高CK血症患儿的起病方式、CK增高的程度和持续时间的考虑对其病因分析有一定帮助,DMD患儿CK升高最为明显,其他依次是炎症性肌病、CMD、代谢性肌病;代谢性肌病患者肌酶波动较大,而先天性肌病和内分泌性肌病肌酶升高不明显.儿童肌病性高CK血症诊断应遵循一定流程,根据临床表现进行生化及代谢筛查、电生理检查、肌活检病理检查及基因检测,并依据病因进行相应治疗.
