| 1 | Fringe pattern analysis using deep learning显示文摘In many optical metrology techniques,fringe pattern analysis is the central algorithm for recovering the underlying phase distribution from the recorded fringe patterns.Despite extensive research efforts for decades,how to extract the desired phase information,with the highest possible accuracy,from the minimum number of fringe patterns remains one of the most challenging open problems.Inspired by recent successes of deep learning techniques for computer vision and other applications,we demonstrate for the first time,to our knowledge,that the deep neural networks can be trained to perform fringe analysis,which substantially enhances the accuracy of phase demodulation from a single fringe pattern.The effectiveness of the proposed method is experimentally verified using carrier fringe patterns under the scenario of fringe projection profilometry.Experimental results demonstrate its superior performance,in terms of high accuracy and edge-preserving,over two representative single-frame techniques:Fourier transform profilometry and windowed Fourier transform profilometry. | Shijie Feng Qian Chen Guohua Gu Tianyang Tao Liang Zhang Yan Hu Wei Yin Chao Zuo | 2019 | Advanced Photonics2019,1,2: | 31 |
| 2 | Modified bottleneck-based heuristic for large-scale job-shop scheduling problems with a single bottleneck显示文摘A modified bottleneck-based (MB) heuristic for large-scale job-shop scheduling problems with a well- defined bottleneck is suggested,which is simpler but more tailored than the shifting bottleneck (SB) procedure. In this algorithm,the bottleneck is first scheduled optimally while the non-bottleneck machines are subordinated around the solutions of the bottleneck schedule by some effective dispatching rules.Computational results indicate that the MB heuristic can achieve a better tradeoff between solution quality and computational time compared to SB procedure for medium-size problems.Furthermore,it can obtain a good solution in a short time for large-scale job- shop scheduling problems. | Zuo Yan Gu Hanyu Xi Yugeng | 2007 | Journal of Systems Engineering and Electronics2007,18,3: | 20 |
| 3 | New precut sphincterotomy for endoscopic retrograde cholangiopancreatography in difficult biliary duct cannulation显示文摘AIM:To retrospectively investigate the effect and safety of various new type precut sphincterotomy techniques (VNTPST) in endoscopic retrograde cholangiopancreato-graphy (ERCP) due to difficult biliary duct cannulation (DBC). METHODS:A plough-like pull-type sphincterotome (PLPTS) or improved short nose sphincterotome or improved needle knife was applied. VNTPST was carried out in 30 of 280 patients,whose biliary tract could not be exposed well or deep cannulation was difficult to perform during ERCP with traditional methods. Patients were followed up for short-term complications and the therapeutic effect of VNTPS was observed and compared with that of traditional endoscopic sphincterotomy (EST). RESULTS:A total 280 patients underwent ERCP,of which 3 failed in operation because of pathological features in stomch or duodenum,247 successfully underwent traditional ERCP (89.1%,247/277),30 failed (10.8%,30/277). VNTPS technique succeeded in 24 (80%,24/30) of 30 cases. The successful rate of deep biliary duct cannulation increased 8.6% (24/277),the total cannulation successful rate following precut was 97.7%. There was a significant difference between the two groups (97.7% vs 89.1%,χ2 = 17.1,P < 0.01). The incidence of complications was 9.3% (26/277) for traditional ERCP group and 13.3% (4/30) for VNTPS technique group. Guideline tip was broken in pancreatic duct (KPDGP) of one patient,and there was no pancreatitis,slight or moderate bleeding postoperatively occurred in 2 patients,1 patient had bleeding during operation (PDWN). There were no differences between VNTPS technique group and traditional ERCP (TRERCP)group (13.3% vs 9.3%,χ2 = 0.478,P > 0.05). CONCLUSION:VNTPS procedure and Deng's precut are highly effective methods to get biliary access during ERCP with DBC. With skillful techniques,it can increase the successful rate for deep cannulation of biliary duct and decrease complications. VNTPS technique,especially Deng's precut is as effective and safe as EST. This technique can be well performed in hospitals without particular equipments. | Deng-Hao Deng Hong-Nei Zuo Jia-Feng Wang Zhi-E Gu Hong Chen Yuan Luo Ming Chen Wen-Nuo Huang Lu Wang Wei Lu | 2007 | World Journal of Gastroenterology2007,13,32: | 20 |
| 4 | Microstructure and Oxidation Behaviors of Nano-particles Strengthened NiCoCrAlY Cladded Coatings on Superalloys显示文摘Nano-particles which can largely improve the microstructure and oxidation resistance of materials are often used as a strengthening component in metal matrix composites. However, few studies were reported on its application in the bond coat of duplex structure thermal barrier coating(TBC). Three kinds of NiCoCrAlY coatings strengthened by different nano-particles with the same addition (1%, mass fraction) were prepared by the laser cladding technique on Ni-based superalloy substrates, aiming to study the effects of the nano-particles on microstructure and oxidation resistance of NiCoCrAlY coatings (the bond coat of the duplex structure thermal barrier coatings). Scanning electron microscope (SEM), X-ray diffractometer(XRD) and thermogravimetry were employed to investigate their morphologies, phases and cyclic oxidation behaviors in atmosphere at 1 050℃, compared with the coating without nano-particles. With the addition of nano-particles, the growth pattern of the grains at the interface changed from epitaxial growth to non-epitaxial growth or part-epitaxial growth; slender dendrites were broken and cellularized; cracks and pores were restrained; and the oxidation weight-gain and the stripping resistance of the oxide scale were improved as well. Among the three kinds of nano-particles, the SiC nano-particles showed the most improvement on microstructure, while the CeO2 nano-particles were insufficient, but its effects on the oxidation resistance are the same as those of the SiC nano-particles. Based on the discussions of the influence mechanism, it is believed that CeO2 nano-particles would show better improvement than SiC nano-particles if the proper amount is added and the proper preparation technique of micro-nanometer composite powders is adopted, with the synergistic action of nanometer effect and reactive element effect. | WANG Hongyu ZUO Dunwen CHEN Xinfeng YU Shouxin GU Yuanzhi | 2010 | Chinese Journal of Mechanical Engineering2010,23,3: | 11 |
| 5 | Impact of enteral nutrition on energy metabolism in patients with Crohn's disease显示文摘AIM: To investigate the impact of enteral nutrition(EN) on the body composition and metabolism in patientswith Crohn's disease(CD). METHODS: Sixty-one patients diagnosed with CD were enrolled in this study. They were given only EN(enteral nutritional suspension, TPF, non-elemental diet) support for 4 wk, without any treatment with corticosteroids, immunosuppressive drugs, infliximab or by surgical operation. Body composition statistics such as weight, body mass index, skeletal muscle mass(SMM), fat mass, protein mass and inflammation indexes such as C-reactive protein(CRP), erythrocyte sedimentation rate(ESR) and CD activity index(CDAI) were recorded before and after EN support. RESULTS: The 61 patients were divided into three groups according to CDAI before and after EN support: A(active phase into remission via EN, n = 21), B(remained in active phase before and after EN, n = 19) and C(in remission before and after EN, n = 21). Patients in group A had a significant increase in SMM(22.11 ± 4.77 kg vs 23.23 ± 4.49 kg, P = 0.044), protein mass(8.01 ± 1.57 kg vs 8.44 ± 1.45 kg, P = 0.019) and decrease in resting energy expenditure(REE) per kilogram(27.42 ± 5.01 kcal/kg per day vs 22.62 ± 5.45 kcal/kg per day, P < 0.05). There was no significant difference between predicted and measured REE in active CD patients according to the HarrisBenedict equation. There was no linear correlation between the measured REE and CRP, ESR or CDAI in active CD patients. CONCLUSION: EN could decrease the hypermetabolism in active CD patients by reducing the inflammatory response. | Jie Zhao Jian-Ning Dong Jian-Feng Gong Hong-Gang Wang Yi Li Liang Zhang Lu-Gen Zuo Yun Feng Li-Li Gu Ning Li Jie-Shou Li Wei-Ming Zhu | 2015 | World Journal of Gastroenterology2015,21,4: | 9 |
| 6 | The spatial pattern of farming and factors influencing it during the Peiligang culture period in the middle Yellow River valley, China显示文摘The Peiligang culture(ca.7000–5000 cal BC)is the earliest Neolithic culture in the middle Yellow River valley and represents the emergence of cereal farming in the region[1].It has long been considered representative of millet farming[2],which requires a dry field,a certain amount of rainfall,and minimal crop management,but new records reveal that mixed farming of millet and rice(Oryza sp.)took place during this period[3].Therefore,it is possible | Can Wang Houyuan Lu Wanfa Gu Naiqin Wu Jianping Zhang Xinxin Zuo Fengjiang Li Daojing Wang Yajie Dong Songzhi Wang Yanfeng Liu Yingjian Bao Yayi Hu | 2017 | Science Bulletin2017,62,23: | 6 |
| 7 | Prevalence of late-onset hypogonadism among middle-aged and elderly males in China:results from a national survey显示文摘This study aimed to propose an operational definition of late-onset hypogonadism(LOH)that incorporates both clinical symptoms and serum testosterone measurements to evaluate the prevalence of LOH in aging males in China.A population-based sample of 6296 men aged 40 years-79 years old was enrolled from six representative provinces in China.Serum total testosterone(TT),sex hormone-binding globulin(SHBG),and luteinizing hormone(LH)were measured and free testosterone(cFT)was calculated.The Aging Males’Symptoms(AMS)scale was used to evaluate the LOH symptoms.Finally,5078 men were included in this analysis.The TT levels did not decrease with age(P=0.59),and had no relationship with AMS symptoms(P=0.87 for AMS total score,P=0.74 for≥3 sexual symptoms).The cFT levels decreased significantly with age(P<0.01)and showed a negative association with the presence of≥3 sexual symptoms(P=0.03).The overall estimated prevalence of LOH was 7.8%(395/5078)if a cFT level<210 pmol l−1 combined with the presence of≥3 sexual symptoms was used as the criterion of LOH.Among them,26.1%(103/395)and 73.9%(292/395)had primary and secondary hypogonadism,respectively.After adjustment for confounding factors,primary and secondary hypogonadism was positively related to age and comorbidities.Body mass index was an independent risk factor for secondary hypogonadism.The results suggest that the AMS total score is not an appropriate indicator for decreased testosterone,and that the cFT level is more reliable than TT for LOH diagnosis.Secondary hypogonadism is the most common form of LOH. | Yi-Jun Liu Xu-Bo Shen Na Yu Xue-Jun Shang Yi-Qun Gu Lian-Dong Zuo Cheng-Liang Xiong Zhen Ye Yuan-Zhong Zhou | 2021 | Asian Journal of Andrology2021,23,2: | 6 |
| 8 | Magnified and enhanced computed virtual chromoendoscopy in gastric neoplasia: A feasibility study显示文摘AIM: To evaluate the feasibility of a new computed virtual chromoendoscopy (CVC) device (M i-scan) in the diagnosis of gastric neoplasia. METHODS: Patients with superficial lesions no larger than 1.0 cm found during high definition endoscopy were included. Those with advanced or obviously protruded or depressed lesions, lesions larger than 1.0 cm and/or lesions which were not amenable to observation by zoom function were excluded. The endoscopist was required to give the real-time descriptions of surface pit patterns of the lesions, based on surface pattern classification of enhanced magnification endoscopy. According to previous reports, types Ⅰ-Ⅲ represent nonneoplastic lesions, and types Ⅳ-Ⅴ represent neoplastic lesions. Diagnosis with M i-scan and biopsy was performed before histopathological diagnosis. Magnified images of gastric lesions with and without enhancement were collected for further analysis. The diagnostic yield of real-time M i-scan and effects on magnification image quality by tone enhancement (TE), surface enhancement (SE) and color enhancement (CE) were calculated. The selected images were sent to another endoscopist. The endoscopist rated the image quality of each lesion at 3 levels. Ratings of image quality were based on visualization of pit pattern, vessel and demarcation line. RESULTS: One hundred and eighty-three patients were recruited. Five patients were excluded for advanced gastric lesions, 1 patient was excluded for poor preparation and 2 patients were excluded for superficial lesions larger than 1.0 cm; 132 patients were excluded for no lesions found by high definition endoscopy. In the end, 43 patients with 43 lesions were included. Histopathology revealed 10 inflammation, 14 atrophy, 10 metaplasia, 1 low grade dysplasia (LGD), 5 high grade dysplasia (HGD) and 3 cancers. For 7 lesions classified into type Ⅰ, histopathology revealed 6 atrophy and 1 metaplasia; for 10 lesions classified into type Ⅱ, histopathology revealed 2 inflammation, 7 atrophy and 1 metaplasia; for 10 lesions classified into type Ⅲ, histopathology revealed 1 inflammation, 8 metaplasia and 1 LGD; for 9 lesions classified into type Ⅳ, histopathology revealed 4 inflammation, 1 atrophy and 4 HGD; for 7 lesions classified into type Ⅴ, histopathology revealed 3 inflammation, 1 HGD and 3 cancers. A total of 172 still images, including 43 images by white light (MWL) and 129 images by M i-scan (43 with TE, 43 with SE and 43 with CE), were selected and sent to the endoscopist who did the analysis. General image quality of M i-scan with TE and SE was significantly better than that of MWL (TE, 4.55 ± 1.07; SE, 4.30 ± 1.02; MWL, 3.25 ± 0.99; P < 0.001). Visualization of pit pattern was significantly improved by M i-scan with SE (1.93 ± 0.25 vs 1.50 ± 0.50, P < 0.001). Microvessel visualization was significantly improved by M i-scan with TE (1.23 ± 0.78 vs 0.76 ± 0.73, P < 0.001). Demarcation line visualization was improved by M i-scan with both TE and SE (TE, 1.75 ± 0.52; SE, 1.56 ± 0.59; MWL, 0.98 ± 0.44; P < 0.001). M i-scan with CE did not show any significant improvements of image quality in general or in the 3 key parameters. Although M i-scan with TE and SE slightly increased the diagnostic yield of MWL, there was no significant difference (P > 0.1). CONCLUSION: Although digital enhancement improves the image quality of magnification endoscopy, its value in improving the diagnostic yield seems to be limited. | Chang-Qing Li Ya Li Xiu-Li Zuo Rui Ji Zhen Li Xiao-Meng Gu Tao Yu Qing-Qing Qi Cheng-Jun Zhou Yan-Qing Li | 2013 | World Journal of Gastroenterology2013,19,26: | 5 |
| 9 | Numerical Simulation of Characteristics of CEX Ions in Ion Thruster Optical System显示文摘Charge exchange(CEX) ions could inflict severe damages on the ion thruster optical system.This article is aimed at investigating the characteristics of the CEX ions and their influences upon the optical system by means of particle-incell(PIC) ion simulation and Monte Carlo collision(MCC) methods.The results from numerical simulation indicate that despite the fact that CEX ions appear in the entire beamlet region near the ion optical system,the ones that present themselves downstream of the accelerator grid have good reason for attracting more attention.As their trajectories are significantly affected by the local electric field,a great number of CEX ions are accelerated toward grids resulting in sputtering erosion.When the influences of the CEX ions are considered in the numerical simulation,there could hardly be observed augments in the screen grid current,but the accelerator grid current increases from zero to 1.4% of the beamlet current.It can be understood from the numerical simulation that the CEX ions formed in the region far downstream of the accelerator grid should be blamed for the erosion on the downstream surface of the accelerator grid. | Zhong Lingwei Liu Yu Li Juan Gu Zuo Jiang Haocheng Wang Haixing Tang Haibin | 2010 | Chinese Journal of Aeronautics2010,23,1: | 5 |

| 12 | Age and geochemistry of the granitoid from the Lunte area,Northeastern Zambia:Implications for magmatism of the Columbia supercontinent显示文摘The Paleoproterozoic tectonic evolution of the Bangweulu Block has long been controversial.Paleoproterozoic granites consisting of the basement complex of the Bangweulu Block are widely exposed in northeastern Zambia,and they are the critical media for studying the tectonic evolution of the Bangweulu Block.This study systematically investigated the petrography,zircon U-Pb chronology,and petrogeochemistry of the granitoid extensively exposed in the Lunte area,northeastern Zambia.The results show that the granitoid in the area formed during 2051±13-2009±20 Ma as a result of Paleoproterozoic magmatic events.Geochemical data show that the granites in the area mainly include syenogranites and monzogranites of high-K calc-alkaline series and are characterized by high SiO2 content(72.68%‒73.78%)and K_(2)O/Na_(2)O ratio(1.82‒2.29).The presence of garnets,the high aluminum saturation index(A/CNK is 1.13‒1.21),and the 1.27%‒1.95%of corundum molecules jointly indicate that granites in the Lunte area are S-type granites.Rare earth elements in all samples show a rightward inclination and noticeably negative Eu-anomalies(δEu=0.16‒0.40)and are relatively rich in light rare earth elements.Furthermore,the granites are rich in large ion lithophile elements such as Rb,Th,U,and K and are depleted in Ba,Sr,and high field strength elements such as Ta and Nb.In addition,they bear low contents of Cr(6.31×10^(−6)‒10.8×10^(−6)),Ni(2.87×10^(−6)‒4.76×10^(−6)),and Co(2.62×10^(−6)‒3.96×10^(−6)).These data lead to the conclusion that the source rocks are meta-sedimentary rocks.Combining the above results and the study of regional tectonic evolution,the authors suggest that granitoid in the Lunte area were formed in a tectonic environment corresponding to the collision between the Tanzania Craton and the Bangweulu Block.The magmatic activities in this period may be related to the assembly of the Columbia supercontinent. | Hong-wei Sun Jun-ping Ren Jie Wang A-lei Gu Xing-yuan Wu Fu-qing He Li-bo Zuo Chipilauka Mukofu Alphet Phaskani Dokowe Ezekiah Chikambwe Zi-jiang Liu Shi Xing | 2021 | China Geology2021,4,4: | 3 |
| 13 | Broadband mid-infrared molecular spectroscopy based on passive coherent optical–optical modulated frequency combs显示文摘Mid-infrared dual-comb spectroscopy is of great interest owing to the strong spectroscopic features of trace gases,biological molecules,and solid matter with higher resolution,accuracy,and acquisition speed. However,the prerequisite of achieving high coherence of optical sources with the use of bulk sophisticated control systems prevents their widespread use in field applications. Here we generate a highly mutually coherent dual midinfrared comb spectrometer based on the optical–optical modulation of a continuous-wave (CW) interband or quantum cascade laser. Mutual coherence was passively achieved without post-data processes or active carrier envelope phase-locking processes. The center wavelength of the generated mid-infrared frequency combs can be flexibly tuned by adjusting the wavelength of the CW seeds. The parallel detection of multiple molecular species,including C_(2)H_(2),CH_(4),H_(2)CO,H_(2)S,COS,and H_(2)O,was achieved. This technique provides a stable and robust dual-comb spectrometer that will find nonlaboratory applications including open-path atmospheric gas sensing,industrial process monitoring,and combustion. | ZHONG ZUO CHENGLIN GU DAOWANG PENG XING ZOU YUANFENG DI LIAN ZHOU DAPING LUO YANG LIU WENXUE LI | 2021 | Photonics Research2021,9,7: | 3 |

| 15 | In-situ constructed three-dimensional MoS_(2)–MoN heterostructure as the cathode of lithium–sulfur battery显示文摘Lithium-sulfur batteries are recognized as one of the most promising next-generation high-performance energy storage systems. However, obstacles like the irreversible capacity loss hinder its broad application. Herein,we fabricated an interconnected three-dimensional MoS_(2)-MoN heterostructure(3D-MoS_(2)-MoN) via a facile salttemplate method, overcoming the intrinsic shortcomings such as poor conductivity and compact morphology of traditionally-synthesized transition metal sulfides(TMSs).Furthermore, excellent electrocatalysis ability and hierarchical pore structure effectively accelerate the sluggish lithium polysulfides conversions during cycling. As a result, 3D-MoS_(2)-MoN showed a high initial specific capacity of 1466 mAh·g^(-1)and excellent high-rate capability up to 4℃. A stable cycling performance with a sulfur loading of 2 mg·cm^(-2) was realized with a low decay rate of 0.069% per cycle. This work introduced a rational design route for the appliance of TMSs in the lithiumsulfur batteries. | Jing-Han Zuo Peng-Bo Zhai Qian-Qian He Lei Wang Qian Chen Xiao-Kang Gu Zhi-Lin Yang Yong-Ji Gong | 2022 | Rare Metals2022,41,5: | 3 |
| 16 | Uncertainty analysis of cross-calibration for HJ-1 CCD camera显示文摘Radiometric calibration of sensor is the basis of quantitative remote sensing,and uncertainty analysis is critical to ensure the accuracy of cross-calibration.Therefore,firstly,cross-calibration formulas were improved by redefining calibration coefficient and spectral band matching factor.In these formulas,cci was redefined as the calibration coefficient of normalized apparent reflectance,and spectral band matching factor as the ratio of normalized apparent reflectance.Secondly,based on the contrast of ideal and actual conditions in cross-calibration,8 sources of cross-calibration uncertainty were proposed:calibration uncertainty of standard sensor;pixel matching uncertainty;spectral band matching factor uncertainty caused by site altitude setting error,atmospheric parameters setting error,surface spectrum source,surface bidirectional reflectance characteristic,and error of atmospheric radiative transfer model;and uncertainty caused by other factors which were not considered.Finally,the contribution of each uncertainty was further analyzed and discussed for the HJ-1 CCD camera.The results provide many valuable references for evaluating the feasibility of alternative cross-calibration measurements. | WANG Zuo XIAO PengFeng GU XingFa FENG XueZhi LI XiaoYing GAO HaiLiang LI Hui LIN JinTang ZHANG XueLiang | 2013 | Chinese Science Bulletin2013,58,7: | 3 |
| 17 | Atacamite and Nantokite in Kaerqueka Copper Deposit of Qimantag Area:Evidence for Cenozoic Climate Evolution of the Qaidam Basin显示文摘Using a mineralogy method to reflect climate evolution is a new approach to research Cenozoic environmental progression of the Qaidam Basin. In this paper, we present the chemical composition and crystallographic parameter of atacamite, nantokite, and tenorite in cryptocrystalline aggregates from the Kaerqueka copper deposit of Qimantag metallogenic belt by means of electron microprobe and in-situ X-ray diffraction analyses. Atacamite and nantokite occur in an intimate intergrowth as the secondary precipitation of chalcopyrite and bornite filling in the interstitial space of andradite in the Kaerqueka copper deposit, with an average composition of Cl: 12.38 wt.%, Cu: 63.76 wt.%, O: 21.46 wt.%. X-ray microdiffraction shows that the intergrowth contains nantokite with a cubic unit cell a=5.403(2) ? and atacamite with an orthorhombic unit cell a=6.030(3), b=6.883(2), c=9.114(1) ?. XRD quantitative calculation shows that the nanometric aggregate contains 36.07 wt.% tenorite, 18.41 wt.% atacamite, and 45.52 wt.% nantokite. The presence of nantokite and atacamite requires saline solutions for their formation and hyper-arid climate conditions for their preservation. Combined with the data of salt lakes and the pollen sequence of western China, we suggest that during the uplift of the Tibetan Plateau and the retreat of the Paratethys, saline water was forced to the surface through a basal fracture zone. In the hyper-arid climate of the Qaidam Basin, the recharge of groundwater by direct precipitation is negligible, and groundwater is derived from inflow from the salt lakes. Thus, atacamite is preserved. In addition, spertiniite in the edge and fractures of atacamite and nantokite may represent wetter climate after the formation of atacamite and nantokite. | Liwen Yi Xiangping Gu Anhuai Lu Xiangyu Li Dexian Zhang Zhiling Wang Jianping Liu Shuai Li Zhengxiang Shu Cui Yu Hongyan Zuo Can Shen | 2017 | Journal of Earth Science2017,28,3: | 3 |
| 18 | 1-13 Constraints on Neutron Skin Thickness in 208Pb and Density-dependent Symmetry Energy显示文摘Nuclear physics interacts with astrophysics, which not only expands its research space but also promotes the development of fundamental physics. Much attention has been paid to the equation of state (EOS) of isospin asymmetric nuclear matter as the development of radioactive beam facilities and astronomical observation facilities. The symmetry energy that measures the isospin-dependence of the EOS is a quantity of critical importance due to its many-sided roles. However, its density dependence remains a great challenge because of the incomplete knowledge of the nuclear force and the complexity of many-body systems. Many important issues in nuclear astrophysics urgently require accurate knowledge about it at present. | Dong Jianmin Zuo Wei Gu Jianzhong | 2015 | IMP & HIRFL Annual Report2015,,1: | 3 |
| 19 | The first data release(DR1) of the LAMOST regular survey显示文摘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. | A-Li Luo Yong-Heng Zhao Gang Zhao Li-Cai Deng Xiao-Wei Liu Yi-Peng Jing Gang Wang Hao-Tong Zhang Jian-Rong Shi Xiang-Qun Cui Yao-Quan Chu Guo-Ping Li Zhong-Rui Bai Yue Wu Yan Cai Shu-Yun Cao Zi-Huang Cao Jeffrey L.Carlin Hai-Yuan Chen Jian-Jun Chen Kun-Xin Chen Li Chen Xue-Lei Chen Xiao-Yan Chen Ying Chen Norbert Christlieb Jia-Ru Chu Chen-Zhou Cui Yi-Qiao Dong Bing Du Dong-Wei Fan Lei Feng Jian-Ning Fu Peng Gao Xue-Fei Gong Bo-Zhong Gu Yan-Xin Guo Zhan-Wen Han Bo-Liang He Jin-Liang Hou Yong-Hui Hou Wen Hou Hong-Zhuan Hu Ning-Sheng Hu Zhong-Wen Hu Zhi-Ying Huo Lei Jia Fang-Hua Jiang Xiang Jiang Zhi-Bo Jiang Ge Jin Xiao Kong Xu Kong Ya-Juan Lei Ai-Hua Li Chang-Hua Li Guang-Wei Li Hai-Ning Li Jian Li Qi Li Shuang Li Sha-Sha Li Xin-Nan Li Yan Li Yin-Bi Li Ye-Ping Li Yuan Liang Chien-Cheng Lin Chao Liu Gen-Rong Liu Guan-Qun Liu Zhi-Gang Liu Wen-Zhi Lu Yu Luo Yin-Dun Mao Heidi Newberg Ji-Jun Ni Zhao-Xiang Qi Yong-Jun Qi Shi-Yin Shen Huo-Ming Shi Jing Song Yi-Han Song Ding-Qiang Su Hong-Jun Su Zheng-Hong Tang Qing-Sheng Tao Yuan Tian Dan Wang Da-Qi Wang Feng-Fei Wang Guo-Min Wang Hai Wang Hong-Chi Wang Jian Wang Jia-Ning Wang Jian-Ling Wang Jian-Ping Wang Jun-Xian Wang Lei Wang Meng-Xin Wang Shou-Guan Wang Shu-Qing Wang Xia Wang Ya-Nan Wang You Wang Yue-Fei Wang You-Fen Wang Peng Wei Ming-Zhi Wei Hong Wu Ke-Fei Wu Xue-Bing Wu Yu-Zhong Wu Xiao-Zheng Xing Ling-Zhe Xu Xin-Qi Xu Yan Xu Tai-Sheng Yan De-Hua Yang Hai-Feng Yang Hui-Qin Yang Ming Yang Zheng-Qiu Yao Yong Yu Hui Yuan Hai-Bo Yuan Hai-Long Yuan Wei-Min Yuan Chao Zhai En-Peng Zhang Hua-Wei Zhang Jian-Nan Zhang Li-Pin Zhang Wei Zhang Yong Zhang Yan-Xia Zhang Zheng-Chao Zhang Ming Zhao Fang Zhou Xu Zhou Jie Zhu Yong-Tian Zhu Si-Cheng Zou Fang Zuo | 2015 | Research in Astronomy and Astrophysics2015,15,8: | 2 |
| 20 | Improved Photovoltaic Performance of MEH-PPV/PCBM Solar Cells via Incorporation of Si Nanocrystals显示文摘当器官的体积异质接面太阳能电池的性能上的第三个部件创作了,我们学习了硅 nanocrystals (SiNCs ) 的效果 poly [2-methoxy,5-(2-ethylhexyloxy )-1,4-phenylene vinylene ](MEH-PPV ):[6,6 ]-phenyl-C61-butyric 酸甲基酉旨(PCBM ) 混合电影。由增加 SiNCs 的合适的数量进 MEH-PPV : PCBM 混合,象外部量效率那样的设备表演,短路电流密度(JSC ) ,和功率变换效率(PCE ) 改善了。在混合的 2.5% SiNCs 的加入导致了 JSC 的 13.6% 改进,它接着导致了 PCE 的 18% 改进直到 2.28% 。改进表演在阴极在从 MEH-PPV/SiNCs 和费用收集的接口的费用产生两个都主要由于改进。 | Quanxiang Yan Lijian Zuo Zhuowei Gu Ligong Yang Rong Wang Mang Wang Hongzheng Chen | 2013 | Chinese Journal of Chemistry2013,31,11: | 2 |
