| 1 | Trend of urban system structure under the restriction of water and land resources in Xinjiang显示文摘根据在 Xinjiang 影响城市的开发和城市的系统结构的水和陆地资源上的研究,这篇论文分析利用地位和城市的水资源的缺乏。城市的水资源的消费和浪费在一个增加趋势,这被考虑。然而,在 Xinjiang 的大多数城市和镇在水资源的缺乏水资源的废物是严肃的,特别在小镇上。megapolis 和中等城市的发展被有限陆地资源显然限制。尽管有扩展小城市和镇的相对大的空格,水和陆地资源的输出好处是低的。为了完成城市的系统的顺序的扩大,在 Xinjiang 组织,在都市化的快速的发展拿一个圆和三条带和节俭资源的策略的城市的空间发展模式被建议。 | ZHANG Xiaolei & LEIJun Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi 830011, China Institute of Geographical Science and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Graduate School, Chinese Academy of Sciences, Beijing 100039, China | 2006 | Chinese Science Bulletin2006，51，A01： | 8 |
| 2 | Synthesis,luminescent properties,and theoretical study of novel Sm^(3+) and Dy^(3+) complexes containing β-diketone and 1,10-phenanthroline显示文摘Two new ternary complexes of 1-(2-thienyl)-3-(p-phenylethynylphenyl)-1,3-propanedione(HTPP) and 1,10-phenanthroline(phen) with Sm3+ and Dy3+ were synthesized.The composition of the ternary complexes was characterized as Sm(TPP)3phen and Dy(TPP)3phen,respectively,by infrared(IR) spectra,chemical analysis,elemental analysis,and thermodynamic analysis.At room temperature,under UV light excitation,the Sm3+ and Dy3+ complexes exhibit characteristic emissions of the central ions.It is found that the fluorescence intensity of Sm(TPP)3phen is stronger than that of Dy(TPP)3phen.In order to explain this phenomenon,an accurate quantum chemistry calculation was carried out,and the result is in good agreement with the experiment data. | LIU Xingwang GAO Saishengtai WANG Li SHEN Leijun JIANG Jiadong GAO Junfang | 2011 | Rare Metals2011，30，1： | 7 |

| 6 | Influence of Annealing Treatment on Microstructure Evolution and Mechanical Property of Friction Stir Weld AZ31 Mg Alloys显示文摘In order to improve microstructure distribution and mechanical properties of Mg alloy joint by annealing treatment, die-casting AZ31 Mg alloy was successfully welded at rotation speed of 1 400 rpm and travel speed of 200 mm/min. The welded joints were annealed at 150-300 ℃ for 15-120 min and then were subjected to transverse tensile. The microstructure of annealed joints was analyzed by optical microscopy and electron backscatter diffraction. The experimental results indicate that(0001) texture intensity in stir zone significantly reduces and sharp transition of grain size is relieved in the interface between stir zone and thermo-mechanically affected zone after annealed at 200 ℃ for 30 min. Meanwhile, the elongation is increased from 7.5% to 13.0% and strength is increased slightly. It is because that annealing treatment can inhibit twin transformation and retain its ability to coordinate deformation during tensile deformation, which contributes to the improvement of plasticity. In addition, annealing treatment can increase the width of interfacial transition zone and lead to gradual transition of grain size between the SZ and TMAZ, which balances dislocation diffusion rate in different zone. | 李亚杰 QIN Fengming LIU Cuirong LI Leijun ZHAO Xiaodong 吴志生 | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，2： | 1 |

| 10 | Calculation of Calibration Functions and Explosive Aftershock Magnitudes in the Near Field显示文摘The current calibration function used in calculating the magnitude of natural earthquakes within 5km is a constant; a fact that causes several serious difficulties for the calculation of the magnitude of small and shallow-focus earthquakes. According to the attenuation law of explosions and the propagation theory of elastic waves, the calibration function is calculated for near field quakes from 0km to 5km. Magnitudes of two aftershock sequences are calculated. The magnitudes of most explosion earthquakes are small, ranging mainly from magnitude -0.5 to 1.0. The M-t chart of the explosive aftershocks is completely different from that of strong earthquake aftershocks. It not only shows positive columnar lines indicating large magnitudes but also short negative columnar lines indicating small magnitudes. | LiXuezheng WangHaijun LeiJun | 2003 | Earthquake Research in China2003，17，4： | 0 |
| 11 | Effect of dynamic loading orientation on fracture properties of surrounding rocks in twin tunnels显示文摘For expedited transportation,vehicular tunnels are often designed as two adjacent tunnels,which frequently experience dynamic stress waves from various orientations during blasting excavation.To analyze the impact of dynamic loading orientation on the stability of the twin-tunnel,a split Hopkinson pressure bar(SHPB)apparatus was used to conduct a dynamic test on the twin-tunnel specimens.The two tunnels were rotated around the specimen’s center to consider the effect of dynamic loading orientation.LS-DYNA software was used for numerical simulation to reveal the failure properties and stress wave propagation law of the twin-tunnel specimens.The findings indicate that,for a twin-tunnel exposed to a dynamic load from different orientations,the crack initiation position appears most often at the tunnel corner,tunnel spandrel,and tunnel floor.As the impact direction is created by a certain angle(30°,45°,60°,120°,135°,and 150°),the fractures are produced in the middle of the line between the left tunnel corner and the right tunnel spandrel.As the impact loading angle(a)is 90°,the tunnel sustains minimal damage,and only tensile fractures form in the surrounding rocks.The orientation of the impact load could change the stress distribution in the twin-tunnel,and major fractures are more likely to form in areas where the tensile stress is concentrated. | Ze Deng Zheming Zhu Lei Zhou Leijun Ma Jianwei Huang Yao Zhang | 2024 | Journal of Rock Mechanics and Geotechnical Engineering2024，16，2： | 0 |
| 12 | Incident and Problem Ticket Clustering and Classification Using Deep Learning显示文摘A holistic analysis of problem and incident tickets in a real production cloud service environment is presented in this paper.By extracting different bags of words,we use principal component analysis(PCA)to examine the clustering characteristics of these tickets.Then Kmeans and latent Dirichlet allocation(LDA)are applied to show the potential clusters within this Cloud environment.The second part of our study uses a pre-trained bidirectional encoder representation from transformers(BERT)model to classify the tickets,with the goal of predicting the optimal dispatching department for a given ticket.Experimental results show that due to the unique characteristics of ticket description,pre-processing with domain knowledge turns out to be critical in both clustering and classification.Our classification model yields 86%accuracy when predicting the target dispatching department. | FENG Hailin HAN Jing HUANG Leijun SHENG Ziwei GONG Zican | 2023 | ZTE Communications2023，21，4： | 0 |
