| 1 | Textural Evolution of AZ31B Magnesium Alloy Sheets Undergoing Repeated Unidirectional Bending at Room Temperature显示文摘In this paper, repeated unidirectional bending (RUB), was applied to improve the texture of AZ31B magnesium alloy sheets so as to enhance their stamping properties. The samples undergoing RUB were annealed at different temperatures. The mechanical properties, formability, textural components and microstructure of the samples before and after RUB were characterized and compared. It was found that the basal textural component was reduced dramatically by RUB, and that (12ˉ12) and (12ˉ11) textural components appeared. Annealing has a great effect on the mechanical properties of samples undergoing RUB. The plasticity and stamping formability of samples were greatly improved by RUB and annealing at 260?C for 1 h, and elongation to fracture and Erichsen value were increased to 38% and 67%, respectively. | Guangsheng Huang Wei Xu Guangjie Huang Hongcheng Li Bo Song | 2009 | Journal of Materials Science & Technology2009，25，3： | 9 |

| 6 | Mechanisms and field test of solution mining by self-resonating cavitating water jets显示文摘Rapid solution mining is the key to cavern construction in salt formations. Rapid solution mining technology with self-resonating cavitating water jets is described in this paper. It can generate three main physical effects: helical flow dissolution, self-resonating cavitating jet erosion, and ultrasonic waves. A self-resonating cavitating nozzle was also designed with the principles based on theory of fluid transients and hydro-acoustics. Under ambient pressure, the experimental results show that the impulse amplitude of pressure reaches a peak at a standoff distance of 5-13 times the nozzle outlet diameter and the cutting ability of self-resonating cavitating jets is twice that of conventional jets under the same conditions. Compared with the conventional mining method, the field test indicates that rapid solution mining technology with self-resonating cavitating jets can speed the construction by more than 2 times at the pocket stage of cavern development. | Song Xianzhi Li Gensheng Yuan Jinping Tian Zhonglan Shen Ruichen Yuan Guangjie Huang Zhongwei | 2010 | Petroleum Science2010，7，3： | 5 |
| 7 | LSTM-based argument recommendation for non-API methods显示文摘Automatic code completion is one of the most useful features provided by advanced IDEs.Argument recommendation,as a special kind of code completion,is widely used as well.While existing approaches focus on argument recommendation for popular APIs,a large number of non-API invocations are requesting for accurate argument recommendation as well.To this end,we propose an LSTM-based approach to recommending non-API arguments instantly when method calls are typed in.With data collected from a large corpus of open-source applications,we train an LSTM neural network to recommend actual arguments based on identifiers of the invoked method,the corresponding formal parameter,and a list of syntactically correct candidate arguments.To feed these identifiers into the LSTM neural network,we convert them into fixed-length vectors by Paragraph Vector,an unsupervised neural network based learning algorithm.With the resulting LSTM neural network trained on sample applications,for a given call site we can predict which of the candidate arguments is more likely to be the correct one.We evaluate the proposed approach with tenfold validation on 85 open-source C applications.Results suggest that the proposed approach outperforms the state-of-the-art approaches in recommending non-API arguments.It improves the precision significantly from 71.46%to 83.37%. | Guangjie LI Hui LIU Ge LI Sijie SHEN Hanlin TANG | 2020 | Science China(Information Sciences)2020，63，9： | 5 |

| 10 | High-efficiency Joining of C_f/Al Composites and TiAl Alloys under the Heat Effect of Laser-ignited Self-propagating High-temperature Synthesis显示文摘The aim of this study was to develop a high-efficiency joining method of Cf/Al composites and TiA l alloys under the heat effect of laser-ignited self-propagating high-temperature synthesis(SHS). The SHS reaction of Ni–Al–Zr interlayer was induced by laser beam and acted as local high-temperature heat source during the joining. Sound joint was obtained and verified the feasibility of this joining method. Effect of filler metals on the joint microstructure and shear strength was evaluated. When the joining pressure was 2 MPa with additive filler metals, joint shear strength reached the maximum of 41.01 MPa. | Zhuoran Li Guangjie Feng Shiyu Wang Shicheng Feng | 2016 | Journal of Materials Science & Technology2016，32，11： | 4 |
| 11 | Effect of Y_2O_3 on Cracking Susceptibility of Laser-Clad Ti-Based Composites Coatings显示文摘Ti-based composite coatings reinforced by in situ synthesized TiB and TiC were deposited on Ti6Al4 V substrates by laser cladding. The effects of Y2O3 on the microstructure and cracking susceptibility of the coatings were investigated in details. It is shown that a small amount of Y2O3 addition can significantly refine the microstructure of the coatings by hastening spheroidization of the primary phase structure. The maximum refinement in microstructure was obtained with the optimum(2 wt%) addition of Y2O3. Moreover, it can increase the volume fraction of TiC and reduce the residual stress of the coatings due to the decrease in lattice distortion of the a(Ti) matrix. All of these factors lead to the reduction in cracking susceptibility of the coatings containing Y2O3 on the premise that the hardness of the coatings is improved. The fracture toughness of the coatings without and with Y2O3(2 wt%) is 8.32 and 17.36 MPa?m1/2, respectively. Scanning electron microscope examination reveals a transition of the fractured surfaces from cleavage fracture to quasi-cleavage fracture resulting from the Y2O3 addition. | 李军 LI Guangjie LUO Xing | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，5： | 3 |
| 12 | Geochronology and geochemistry of Cretaceous-Eocene granites,Tengchong Block(SW China):Petrogenesis and implications for Mesozoic-Cenozoic tectonic evolution of Eastern Tethys显示文摘The Early Cretaceous-Early Eocene granitoids in the Tengchong Block record the evolutionary history of the Mesozoic-Cenozoic tectono-magmatic evolution of Eastern Tethys.(a)The Early Cretaceous granitoids with relatively low(^(87)Sr/^(86)Sr)iratios of 0.7090-0.7169 andε_(Nd)(t)values of-9.8 to-7.8 display metaluminous,calc-alkaline dominated by I-type granite affinity and hybrid mantle-crust geochemical signatures.They may have been derived from melting of the subducted Meso-Tethyan BangongNujiang oceanic crust with terrigenous sediments in an arc-continent collisional setting.(b)The Late Cretaceous-Paleocene granitoids with relatively high(^(87)Sr/^(86)Sr)iratios of 0.7109-0.7627,andε_(Nd)(t)values of-12.1 to-7.9 exhibit metaluminous to peraluminous,calc-alkaline dominated by S-type granite affinity and hybrid Lower-Upper crust geochemical signatures,which may be originated from partial melting of the Meso-Proterozoic continental crust in the collision setting between the Tengchong Block and Baoshan Block.(c)The Early Eocene granitoids have metaluminous,calc-alkaline I-type and S-type granites dual affinity,with relatively high(^(87)Sr/^(86)Sr)iratios of 0.711-0.736,ε_(Nd)(t)values of-9.4 to-4.7,showing crust-mantle mixing geochemical signatures.They may have been originated from partial melting of the late Meso-Proterozoic upper crustal components mixed with some upper mantle material during the ascent process of mantle magma caused by the subduction of the Neo-Tethyan Putao-Myitkyian oceanic crust,and collision between the Western Burma Block and the Tengchong Block.It is these multi-stage subductions and collisions that caused the spatial and temporal distribution of the granitic rocks in the Tengchong Block. | Yongqing Chen Guangjie Li Luxue Qin Yingxiang Lu Chengxing Jiang | 2022 | Geoscience Frontiers2022，13，2： | 3 |
| 13 | Analysis of stability for Taizishang slope under condition of atomization rainfall of jet overflows显示文摘Taizishang slope of Qingjiang Reservoir in Huibei is within the range of atomization rainfall. The authors created the finite element model with ANSYS 10.0 and used strength reduction FEM to calculate thesafety coefficient of the slope on conditions with no rain, and theatomization rainfall lasting for 0.2 hours and 0.4 hours. The results show that the atomization rainfall would decrease the stability of the slope, and with rainfalls increasing, the stability would reduce much more. | CHAI Beibei LI Guangjie YANG Zhishuang | 2011 | Global Geology2011，14，4： | 2 |
| 14 | Global patterns and changes of carbon emissions from land use during 1992e2015显示文摘Carbon emissions from land use(ELUC)are an important part of anthropogenic CO_(2) emissions,but its size and location remain uncertain,and our knowledge of the relationship between ELUC and GDP remains partial.We showed that the carbon emissions directly caused by land use change(direct ELUC)during 1992-2015 was 26.54 Pg C(1.15 Pg C yr^(-1)),with a decreased trend and a net reduction rate of0.15 Pg C yr^(-1).The areas that exhibited reductions were concentrated in South America,Central Africa,and Southeast Asia,and those with increments were scattered in Northwestern North America,Eastern South America,Central Africa,East Asia,and parts of Southeast Asia.For the indirect carbon emissions from the utilization of built-up land(indirect ELUC),it manifested an upward trend with a total emission of 27.51 Pg C(1.2 Pg C yr^(-1)).The total value resulted by global ELUC was $136.3×10^(9) US,and the value of annual was equivalent to 3.7 times the GDP of the Central African Republic in 2015($5.93×10^(9) US yr^(-1)).Among the 79 countries and regions considered in this study,54 represented the upward GDP with increased emissions,and only 25 experienced GDP growth with emission reductions.These findings highlight the pivotal role of land use change in the carbon cycle and the significance of coordinated development between GDP and carbon emissions. | Shiqi Tian Shijie Wang Xiaoyong Bai Guangjie Luo Qin Li Yujie Yang Zeyin Hu Chaojun Li Yuanhong Deng | 2021 | Environmental Science and Ecotechnology2021，，3： | 2 |
| 15 | Risk assessments of debris flow based on improved analytic hierarchy process and efficacy coefficient method显示文摘In order to evaluate the danger of debris flow properly, eight factors were selected as the risk assessment indexes of the debris flow, namely the vertical slope, valley relative difference, hillside slope, area of basin, loose solid material reserves, the path length of sediment supply probability, silting and scouring derricking and vegetation coverage. The improved Analytic Hierarchy Process (AHP) method was used to obtain the weights of the factors; and the efficacy coefficient method was adopted to evaluate the risks of six typical debris flow gullies. According to the research, the improved AHP method not only avoids the subjectivity in the individual factor valuation by comparing two factors of each layer, but also makes the subsequent consistency check unnecessary. | LIU Guochao LI Guangjie YANG Lina | 2012 | Global Geology2012，15，3： | 2 |
| 16 | STABILITY ANALYSIS OF THE SPLIT-STEP THETA METHOD FOR NONLINEAR REGIME-SWITCHING JUMP SYSTEMS显示文摘In this paper,we investigate the stability of the split-step theta(SST)method for a class of nonlinear regime-switching jump systems–neutral stochastic delay differential equations(NSDDEs)with Markov switching and jumps.As we know,there are few results on the stability of numerical solutions for NSDDEs with Markov switching and jumps.The purpose of this paper is to enrich conclusions in such respect.It first devotes to show that the trivial solution of the NSDDE with Markov switching and jumps is exponentially mean square stable and asymptotically mean square stable under some suitable conditions.If the drift coefficient also satisfies the linear growth condition,it then proves that the SST method applied to the NSDDE with Markov switching and jumps shares the same conclusions with the exact solution.Moreover,a numerical example is demonstrated to illustrate the obtained results. | Guangjie Li Qigui Yang | 2021 | Journal of Computational Mathematics2021，39，2： | 1 |

| 19 | Achieving ultra-high strength using densely ultra-fine LPSO phase显示文摘Long period stacking ordered(LPSO) structures are an effective strengthening phase in Mg alloys.However,the coarse LPSO phases in as-cast alloys are very difficult to refine,and they dramatically reduce the strengthening effect.In the present study,friction stir processing(FSP) was employed to refine the structure of an Mg-12.8 Y-4.7 Zn(wt%) alloy with a very high content of coarse LPSO phases.An optimized FSP regime refined the coarse LPSO phases into densely ultrafine blocks with an average width of ~200 nm and an average length of~1 μm.An ultrahigh yield strength of ~800 MPa was achieved under compression of the FSP region.Theoretical calculations indicated that the strengthening by the densely ultrafine LPSO phases was up to approximately 630 MPa. | Changzheng Li Huan Liu Yunchang Xin Bo Guan Guangjie Huang Peidong Wu Qing Liu | 2022 | Journal of Materials Science & Technology2022，，34： | 1 |
