| 5 | Preparation and characterization of microcapsule containing epoxy resin and its self-healing performance of anticorrosion covering material显示文摘Microencapsulated healing agents that possess adequate strength,long shelf-life,and excellent bonding to the host material are required for self-healing materials. The in situ encapsulation method is demonstrated over an order of magnitude size reduction for the preparation of urea-formaldehyde(UF) capsules filled with a healing agent,a mixture epoxy resin of the epoxy 711 and E-51. Capsules with diameters as small as about 100 μm are achieved under the agitation rate of 800 r min-1. The capsules possess a uniform UF shell wall(4 μm average thickness) . By using the analysis of scanning electronic microscope(SEM) ,thermal analysis(TG-DTA) and FTIR,the characteristics of the microcapsules were investigated respectively. Successful self-healing has been demonstrated for anticorrosion covering materials with microcapsules. | LIAO LePing ZHANG Wei XIN Yi WANG HongMei ZHAO Yang LI WuJun | 2011 | Chinese Science Bulletin2011，56，4： | 8 |
| 6 | A New Fire Detection Method Using a Multi-Expert System Based on Color Dispersion, Similarity and Centroid Motion in Indoor Environment显示文摘In this paper, a video fire detection method is proposed, which demonstrated good performance in indoor environment. Three main novel ideas have been introduced. Firstly, a flame color model in RGB and HIS color space is used to extract pre-detected regions instead of traditional motion differential method, as it’s more suitable for fire detection in indoor environment. Secondly, according to the flicker characteristic of the flame, similarity and two main values of centroid motion are proposed. At the same time, a simple but effective method for tracking the same regions in consecutive frames is established. Thirdly,a multi-expert system consisting of color component dispersion,similarity and centroid motion is established to identify flames.The proposed method has been tested on a very large dataset of fire videos acquired both in real indoor environment tests and from the Internet. The experimental results show that the proposed approach achieved a balance between the false positive rate and the false negative rate, and demonstrated a better performance in terms of overall accuracy and F standard with respect to other similar fire detection methods in indoor environment. | Teng Wang Leping Bu Zhikai Yang Peng Yuan Jineng Ouyang | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，1： | 7 |
| 7 | Formation keeping control through inter-satellite electromagnetic force显示文摘Satellite formation keeping through inter-satellite electromagnetic force provides an attractive alternative for future space missions due to its distinct advantages of no propellant consumption or plume contamination as compared to conventional approaches.However,the internal force nature as well as the high nonlinearity and coupling of electromagnetic force brings new control challenges for this novel technique.In this paper,analysis on the dynamics characteristics and special control issues in the presence of electromagnetic force is carried out on the basis of the derived relatively translational dynamics.Considering the model uncertainties,external disturbances and sensor noise,a combined nonlinear control scheme involving feed-forward and feedback control components is proposed for electromagnetic-force-based formation keeping.The feed-forward component is directly obtained through desired configuration and dynamics under nominal conditions while the feedback component is realized utilizing active disturbance rejection control methodology with some reasonable improvement.Numerical simulation is presented to verify the feasibility and validity of the combined control scheme. | CAI WeiWei YANG LePing ZHU YanWei ZHANG YuanWen | 2013 | Science China(Technological Sciences)2013，56，5： | 4 |
| 8 | Mesomechanics Finite-element Method for Determining the Shear Strength of Mudded Intercalation Materials显示文摘A new method regarding mesomechanics finite-element research is proposed to predict the peak shear strength of mudded intercalation materials on a mesoscopic scale. Based on geometric and mechanical parameters, along with the strain failure criteria obtained by sample's deformation characteristics, uniaxial compression tests on the sample were simulated through a finite-element model, which yielded values consistent with the data from the laboratory uniaxial compression tests, implying that the method is reasonable. Based on this model, a shear test was performed to calculate the peak shear strength of the mudded intercalation, consistent with values reported in the literature, thereby providing a new approach for investigating the mechanical properties of mudded intercalation materials. | 胡启军 SHI Rendan YANG Xiaoqiang CAI Qijie HE Tianjun HE Leping | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，2： | 2 |
| 9 | A guidance method for coplanar orbital interception based on reinforcement learning显示文摘This paper investigates the guidance method based on reinforcement learning(RL)for the coplanar orbital interception in a continuous low-thrust scenario.The problem is formulated into a Markov decision process(MDP)model,then a welldesigned RL algorithm,experience based deep deterministic policy gradient(EBDDPG),is proposed to solve it.By taking the advantage of prior information generated through the optimal control model,the proposed algorithm not only resolves the convergence problem of the common RL algorithm,but also successfully trains an efficient deep neural network(DNN)controller for the chaser spacecraft to generate the control sequence.Numerical simulation results show that the proposed algorithm is feasible and the trained DNN controller significantly improves the efficiency over traditional optimization methods by roughly two orders of magnitude. | ZENG Xin ZHU Yanwei YANG Leping ZHANG Chengming | 2021 | Journal of Systems Engineering and Electronics2021，32，4： | 2 |

| 13 | Optimal reconfiguration of constellation using adaptive innovation driven multiobjective evolutionary algorithm显示文摘Constellation reconfiguration is a critical issue to recover from the satellite failure,maintain the regular operation,and enhance the overall performance.The constellation reconfiguration problem faces the difficulties of high dimensionality of design variables and extremely large decision space due to the great and continuously growing constellation size.To solve such real-world problems that can be hardly solved by traditional algorithms,the evolutionary operators should be promoted with available domain knowledge to guide the algorithm to explore the promising regions of the trade space.An adaptive innovationdriven multi-objective evolutionary algorithm(MOEA-AI)employing automated innovation(AI)and adaptive operator selection(AOS)is proposed to extract and apply domain knowledge.The available knowledge is extracted from the final or intermediate solution sets and integrated into an operator by the automated innovation mechanism.To prevent the overuse of knowledgedependent operators,AOS provides top-level management between the knowledge-dependent operators and conventional evolutionary operators.It evaluates and selects operators according to their actual performance,which helps to identify useful operators from the candidate set.The efficacy of the MOEAAI framework is demonstrated by the simulation of emergency missions.It was verified that the proposed algorithm can discover a non-dominant solution set with better quality,more homogeneous distribution,and better adaptation to practical situations. | HU Jiaxin YANG Leping HUANG Huan ZHU Yanwei | 2021 | Journal of Systems Engineering and Electronics2021，32，6： | 1 |
| 14 | Ti2AlC triggered in-situ ultrafine TiC/Inconel 718 composites:Microstructure and enhanced properties显示文摘In situ ultrafine TiC dispersion reinforced Inconel 718 alloy with enhanced mechanical properties was fabricated by the technique of reactive hot-press sintering Ti2AlC and In718 powders.The effect of Ti2AlC precursor additions(5 vol.%,10 vol.%,15 vol.%)on microstructure and mechanical properties of TiC/In718 composites were investigated.A relationship of microstructural characteristics,room and elevated temperature mechanical performance,and underlying strengthening mechanisms were analyzed.The results show that initial Ti2AlC precursor transformed completely into ultrafine TiC particulate(~230 nm)and distributed uniformly in the matrix after sintering 5 and 10 vol.%Ti2AlC/In718.However,TiC particulates tended to aggregate to stripes with the addition of Ti2AlC up to 15 vol.%,which,in adverse,weaken the properties of In718.The 5 vol.%Ti2AlC/In718 sample showed a higher tensile strength of 1404±13 MPa with a noticeable elongation of 9.8%at room temperature compared to the pure In718(ultimate tensile strength(UTS)=1310 MPa,elongation=21.5%).At 600℃,700℃,800℃and 900℃,tensile strength of the as-sintered 5 vol.%Ti2AlC/In718 composite was determined to be 1333±13 MPa,1010±10 MPa,685±25 MPa and 276±3 MPa,increased by 9.2%,14.6%,14.2%and 55%,respectively,compared with that of monolithic In718 alloy.The excellent tensile properties of TiC/In718 composite can be ascribed to the combined mechanisms in term of increased dislocation density,dispersive Orowan and load transfer mechanisms. | Wenqiang Hu Zhenying Huang Qun Yu Yuanbo Wang Yidan Jiao Cong Lei Leping Cai Hongxiang Zhai Yang Zhou | 2020 | Journal of Materials Science & Technology2020，47，16： | 1 |

| 16 | Ternary PtSmCo NPs electrocatalysts with enhanced oxygen reduction reaction显示文摘PtSmCo ternary metal nanoparticles(NPs)were synthesized as electrocatalysts for oxygen reduction reaction(ORR).Firstly,SmCo NPs were prepared by potentiostatic electrodeposition in ionic liquids(ILs),and the average particle diameter of SmCo NPs corresponds to about 238 nm(-0.65 V),72 nm(-0.75 V)and 45 nm(-0.85 V),respectively.Secondly,displacement and reductions of SmCo NPs occur in the K2 PtCl4 and L-ascorbic acid sodium with about 3 nm of Pt NPs which grow on the surface of SmCo NPs to form PtSmCo ternary metal NPs.Studies of cycle voltammetry(CV)and line sweep voltammetry(LSV)indicate that the electrocatalytic property for ORR generates a decreasing order of commercial Pt/C>PtSmCo0.85>PtSmCo0.75>PtSmCo0.65.Accelerated durability testing(ADT)after 10000 cycles shows that PtSmCo0.85 NPs electrocatalyst decreases by-40%in electrochemical active surface areas(ECSA),the half-wave potential(E1/2)only negatively shifts by 14 mV and decreases by^13.6%in mass activity(MA).When compared with JM Pt/C,where it decreases by^49%in ECSA,E1/2 is negatively shifted by 40 mV and decreased by^50%in MA.Therefore,PtSmCo0.85 NPs electrocatalyst is more stable than JM Pt/C. | Qinghua Gong Leping Wang Ni Yang Lin Tian Gang Xie Bing Li | 2020 | Journal of Rare Earths2020，38，12： | 1 |

| 18 | Paleogene-Neogene stratigraphic realm and tectonic-sedimentary evolution of the Qilian Mountains and their surrounding areas显示文摘The Cenozoic uplift of Qilian Mountains is critical to comprehend the uplift and extension of the Tibet Plateau as well as the formation of the first and second steps in China's topography. This study summarized dynamic stratigraphic realm comprehensively on the basis of stratigraphic correlation of different Cenozoic sedimentary basin regions of the Qilian Mountains and adjacent mountains. This facilitated the re-creation of the tectonic-sedimentary evolutionary process of the Qilian Mountains and their surrounding areas. The results indicate that during the Early Paleogene(Paleocene-Eocene), the Qilian Mountains were part of an uplift realm. During the Oligocene, Guide-Xining-Lanzhou-Linxia sag basin at the northern margin of the West Qinling Mountains came into being and was subjected to sedimentation. The Suli Basin located between the North and South Qilian paleo-uplifts began to form and undergo sedimentation. Intracontinental orogenic extrusion and basin detachment occurred at the Qilian Mountains during the Miocene, which caused successive uplifts of various mountains, including the Laji, South Qinghai,Jishi, Liupan, and South Shule Mountains. Until Pliocene, Qilian Mountains uplifted continuously and resulted in the shrink,extinction and being eroded of the basins, and aeolian red clay started to accumulate. | YANG LiRong LI JianXing YUE LePing WANG HongLiang GUO HuaiJun ZHU XiaoHui ZHU Tao DU Kai ZHANG Rui ZHANG YunXiang GONG HuJun | 2017 | Science China Earth Sciences2017，60，5： | 1 |
