| 2 | Mission decision-making method of multi-aircraft cooperatively attacking multi-target based on game theoretic framework显示文摘Coordinated mission decision-making is one of the core steps to effectively exploit the capabilities of cooperative attack of multiple aircrafts. However, the situational assessment is an essential base to realize the mission decision-making. Therefore, in this paper, we develop a mission decision-making method of multi-aircraft cooperatively attacking multi-target based on situational assessment. We have studied the situational assessment mathematical model based on the Dempster-Shafer(D-S) evidence theory and the mission decision-making mathematical model based on the game theory. The proposed mission decision-making method of antagonized airfight is validated by some simulation examples of a swarm of unmanned combat aerial vehicles(UCAVs)that carry out the mission of the suppressing of enemy air defenses(SEAD). | Yao Zongxin Li Ming Chen Zongji Zhou Rui | 2016 | Chinese Journal of Aeronautics2016,29,6: | 16 |
| 3 | MECHANICAL PROPERTIES OF FINE PITCH DEVICES SOLDERED JOINTS BASED ON CREEP MODEL显示文摘Nonlinear analyses of quad flat package (QFP) on printed circuit board (PCB) assemblies subjected to thermal cycling conditions are presented.Two different solders are considered,namely, Sn37Pb and Sn3.5Ag.The stress and strain response of fine pitch devices soldered joints was investigated by using finite element method based on Garofalo-Arrheninus model.The simulated results indicate creep distribution of soldered joints is not uniform,the heel and toe of soldered joints, the area between soldered joints and leads are the creep concentrated sites.The similar phenomena of stress curves simulated based on Garofalo-Arrhenlnus model and Anand equations is confirmed,and the creep strain value of Sn3.5Ag soldered joints is lower than that of Sn37Pb soldered joints. Thermal cycling results show that Sn3.5Ag strongly outperforms Sn37Pb for QFP devices under the studied test condition.This is well matched with the experimental outcome analyzed.In addition,the soldered devices were tested by micro-joints tester,the tensile strength of Sn3.5Ag soldered joints is found to be higher than that of Sn37Pb soldered joints.By analyzing the fracture microstructure of soldered joints,it is found that fracture mechanism of Sn3.5Ag soldered joints is toughness fracture, while fracture mechanism of Sn37Pb soldered joints includes brittle fracture and toughness fracture. The results of this study provide an important basis of understanding the mechanical properties of fine pitch devices with traditional Sn37Pb and Sn3.5Ag lead-free soldered joints. | ZHANG Liang XUE Songbai HAN Zongjie WANG Jianxin GAO Lili SHENG Zhong | 2008 | Chinese Journal of Mechanical Engineering2008,21,6: | 12 |

| 5 | Sliding mode disturbance observer-based backstepping control for a transport aircraft显示文摘This paper presents a novel control method by integrating the sliding mode disturbance observerbased control and the backstepping control technique,and successfully applies it to a flight control system for heavy cargo airdrop operations.The super-twisting second order sliding mode disturbance observer(SOSMDO)is employed to estimate bounded but otherwise arbitrary disturbances,thus ensuring asymptotic convergence of the estimation error to zero in a finite time.Besides,the integrated controller can significantly improve the robustness of the flight control system to modeling uncertainty and external disturbance in the presence of state/control constraints.The closed-loop stability is guaranteed in the sense of Lyapunov.In addition,the proposed approach can considerably reduce design cycles.The performance of the proposed control method is demonstrated in a very low altitude extraction airdrop simulation with a high-fidelity six-degree-of-freedom transport aircraft model. | ZHANG Chao CHEN ZongJi WEI Chen | 2014 | Science China(Information Sciences)2014,57,5: | 10 |
| 6 | EFFECTS OF LEAD WIDTHS AND PITCHES ON RELIABILITY OF QUAD FLAT PACKAGE(QFP)SOLDERED JOINTS显示文摘有限元素方法(女性) 被用来在焊接关节的可靠性上分析铅宽度和程度的效果。为 QFP 设备的最佳模拟也被研究。结果显示当铅程度是一样时,焊接关节的最大的相等的压力与增加铅宽度增加,当焊接关节的可靠性减少时。当铅宽度是一样时,焊接关节的最大的相等的压力不与增加铅程度完全减少,最大的相等的压力价值的最小的价值在所有曲线存在。在这个条件下面,焊接关节的最大的相等的压力是相对最不,焊接关节的可靠性高,集会是优秀的。模仿的结果显示最好的参数:铅宽度是 0.2 公里,铅沥青是 0.3 公里(在二领先之间的距离是 0.1 公里) ,它现在为 QFP 设备的 micromation 被有益于。当铅宽度是 0.25 公里,铅沥青是 0.35 公里时,焊接关节的最大的相等的压力的最小的值存在(在二领先之间的距离是 0.1 公里) ,设备能很长时间服务,可靠性最高,汇编是优秀的。模仿的结果也显示铅宽度是 0.15 公里和铅沥青的事实也许是 0.2 公里 QFP 的限制,它为高级的铅计数和汇编的 micromation 是重要的。 | XUE Songbai WU Yuxiu HAN Zongjie WANG Jianxin | 2007 | Chinese Journal of Mechanical Engineering2007,20,4: | 7 |
| 7 | Effect of biodiesel on the particle size distribution in the exhaust of common-rail diesel engine and the mechanism of nanoparticle formation显示文摘Effect of biodiesel blends on the particle size distribution (PSD) of exhaust aerosol and the mechanism of nanoparticle formation were investigated with a modern common rail light-duty diesel engine. The results showed that PSD of diesel included two modes:nucleation mode (NM) and accumulation mode (CM). The criterion diameter of the two modes is 50 nm. Only CM was observed for all fuels under the condition of 50 N.m,2000 r/min. When the engine torque was higher than 150 N.m,log-modal PSD of diesel shifted to bimodal. At higher loads,if the biodiesel blend ratio was below 60%,the PSD of biodiesel blends still included the two modes. However,no NM particles were found for pure biodiesel. At lower loads,only CM was found in PSD of all fuels. Significant reduction of CM particles was found for biodiesel blends compared with diesel. Discussion on the mechanism of nanoparticle formation indicated that for the light-duty diesel engine with oxidation catalysts,fuel consumption and exhaust temperature increased with increasing the engine loads,and SO2 was converted to SO3 by catalyst which,in its hydrated form,could act as the precursor for biodiesel NM formation. Therefore,sulfur level of biodiesel blends dominates the nanoparticle formation in light-duty diesel engine with oxidation catalysts. | ZHANG XuSheng ZHAO Hui HU ZongJie WU ZhiJun LI LiGuang | 2009 | Science China(Technological Sciences)2009,52,9: | 5 |
| 8 | Analysis of Rockfall and Its Impact on the Cut-and-Cover Tunnel in Dynamics显示文摘This paper presents the effect of thickness of Buffer layer on the safety of cut-and-cover tunnel under the given magnitude and height of rockfall, and the limit load of the structure. To establish calculating models of rockfall in different conditions, the dynamics of the fall down to the surface of the slope is taken into account and the exterior characteristics of the rockfall is analyzed. We have derived the formula for calculating velocity of rocks before and after collision, calculated the impact load upon the structures below and the limit load, and compared the impact force and limit load to judge the safety of the structure. Finally, the validity of models is approved by the safety evaluation of cut-and-cover tunnel in the mouth of Heshang Mountain in Nandan County. | SONG Shuzhi KONG Jiming WANG Chenghua CHENG Zefu YANG Zongji | 2006 | Wuhan University Journal of Natural Sciences2006,11,4: | 5 |
| 9 | Diode Laser Soldering Technology of Fine Pitch QFP Devices显示文摘The laser provides a controllable means of supplying localized energy for solder joint formation and is a valuable tool in electronics manufacture.Diode laser soldering for fine pitch QFP devices were carried out with Sn-Ag-Cu lead-free solder and Sn-Pb solder respectively,and the mechanical properties of micro-joints of the QFP devices were tested and studied by STR-1000 micro-joints tester.The results indicate that sound QFP micro-joints without bridging or solder ball are gained by means of diode laser soldering method with appropriate laser processing parameters,and the pitch of the QFP devices is as fine as to 0.4mm.Tensile strength of QFP micro-joints increases gradually with the increase of laser output power,the maximum tensile strength presents when the laser output power increase to a certain value.The results also indicate that the mechanical properties of QFP micro-joints soldered by diode laser soldering system are better than those of QFP micro-joints soldered by IR reflow soldering method.The experimental results may provide a theory guide for investigation of diode laser soldering. | XUE Songbai ZHANG Liang HAN Zongjie WANG Jianxin YU Shenglin | 2011 | Chinese Journal of Mechanical Engineering2011,24,5: | 5 |
| 10 | Modification of wettability of stainless steel by picosecond laser surface microstructuring显示文摘We report on the modification of the wettability of stainless steel by picosecond laser surface microstructuring in this paper. Compared with traditional methods, picosecond laser-induced surface modification provides a fast and facile method for surface modification without chemical damage and environmental pollution. As a result of treatment by 100 ps laser pulses, microstructures are fabricated on the stainless steel sample surface, contributing to the increase of the contact angle from 88° to 105°, which realizes a transformation from hydrophilicity to hydrophobicity. The morphological features of fabricated microstructures are characterized by scanning electron microscopy and optical microscopy. | Zongjie Bao Chengwei Wang Yang Zhang Quan-Zhong Zhao | 2015 | Photonics Research2015,3,4: | 5 |
| 11 | On the asymmetric distribution of heat loss from the Earth'sinterior显示文摘Mean heat flows and heat losses of the Northern and Southern hemispheres are calculated using degree 12 spherical harmonic representation of the global heat flow field (Pollack et al., 1993). Mean heat flows and heat losses of 0° hemisphere and 180° hemisphere, with median lines being 0° longitude and 180° longitude, are also calculated. The mean heat flow of the Southern Hemisphere is 99.3 mW·m -2, significantly higher than that of the Northern Hemisphere (74.0 mW·m -2). The mean heat flow of 0° hemisphere (94.1 mW·m -2) is also higher than the value of 180° hemisphere (79.3 mW·m -2). The mantle heat loss from the Southern Hemisphere is 22.1×10 12 W, as twice as that from the Northern Hemisphere ( 10.8×10 12 W). The 16.9×10 12 W mantle heat loss from 0° hemisphere is close to 16.0×10 12 W from 180° hemisphere. The hemispherical asymmetry of global heat loss is originated by the asymmetry of geographic distribution of continents and oceans. The asymmetric distribution of heat loss is a long-term phenomenon in the geological history. | Yang Wang Jiyang Wang Zongji Ma | 1998 | Chinese Science Bulletin1998,43,18: | 4 |
| 12 | Improved photocatalytic activity of nano CuO-incorporated TiO_2 granules prepared by spray drying显示文摘4 wt% CuO–96 wt% TiO2 granules were prepared by a spray drying process. The microstructure and optical property of CuO–TiO2 granules were studied. The results indicate that copper existed in the form of CuO. The spray dried granules possess spherical geometry and smooth surface with grain size in the range of 40–80 μm. CuO–TiO2 has a relatively smaller E g value(2.85 eV) than Ti O2(3.17 eV). The photocatalytic property of CuO–TiO2 granules was investigated by degradation of a model pollutant(the azo dye methyl orange) under the irradiation of the xenon lamp equipped with a band pass fi lter of 365 nm. The CuO–TiO2spray-dried granules degrade about 10% more MO than TiO2spray-dried granules under UV irradiation within the same time. The XPS spectra suggested that Cu2 tand reduced copper species were coexistent in reacted CuO–TiO2 photocatalyst. The improvement of photocatalytic activity for CuO–TiO2 was mainly attributed to effective separation of photogenerated electron–hole pairs in the presence of CuO. | Zongjie Liu Chungen Zhou | 2015 | Progress in Natural Science:Materials International2015,25,4: | 2 |
| 13 | Preparation of Nano-Sized γ-Al_2O_3 Supported Iron Catalyst for Fischer-Tropsch Synthesis by Solvated Metal Atom Impregnation Methods显示文摘Two types of small iron clusters supported onγ-Al2O3-RT(dehydroxylated at room temperature) andγ-Al2O3-800 (dehydroxylated at 800℃) were prepared by solvated metal atom impregnation (SMAI) techniques. The iron atom precursor complex, bis(toluene)iron(0) formed in the metal atom reactor, was impregnated intoγ-Al2O3 having different concentrations of surface hydroxyl groups to study the effect of surface hydroxylation on the crucial stage of iron cluster formation. Catalysts prepared in this way were characterized by TEM, Mossbauer, and chemisorption measurements, and the results show that higher concentration of surface hydroxyl groups ofγ-Al2O3-RT favors the formation of more positively charged supported iron cluster Fen/γ-Al2O3-RT, and the lower concentration of surface hydroxyl groups ofγ-Al2O3-800 favors the formation of basically neutral supported iron cluster Fen/γ-Al2O3-800. The measured results also indicate that the higher concentration of surface hydroxyl groups causes the rapid decomposition of precursor complex, bis(toluene)iron(0), and favors the formation of relatively large iron cluster. Consequently, these two types of catalysts show different catalytic properties in Fischer-Tropsch reaction. The catalytic pattern of Fen/γ-Al2O3-RT in F-T reaction is similar to that of the unreducedα-Fe2O3 and that of Fen/γ-Al2O3-800 is similar to that of the reducedα-Fe2O3. | Lihua Yu Xiaoxiang Zhang Zongjie Du Da Wang Shurong Wang Shihua Wu | 2007 | Journal of Natural Gas Chemistry2007,16,1: | 2 |
| 14 | Hollow Gradient-Structured Iron-Anchored Carbon Nanospheres for Enhanced Electromagnetic Wave Absorption显示文摘In the present paper,a microwave absorber with nanoscale gradient structure was proposed for enhancing the electromagnetic absorption performance.The inorganic-organic competitive coating strategy was employed,which can effectively adjust the thermodynamic and kinetic reactions of iron ions during the solvothermal process.As a result,Fe nanoparticles can be gradually decreased from the inner side to the surface across the hollow carbon shell.The results reveal that it offers an outstanding reflection loss value in combination with broadband wave absorption and flexible adjustment ability,which is superior to other relative graded distribution structures and satisfied with the requirements of lightweight equipment.In addition,this work elucidates the intrinsic microwave regulation mechanism of the multiscale hybrid electromagnetic wave absorber.The excellent impedance matching and moderate dielectric parameters are exhibited to be the dominative factors for the promotion of microwave absorption performance of the optimized materials.This strategy to prepare gradient-distributed microwave absorbing materials initiates a new way for designing and fabricating wave absorber with excellent impedance matching property in practical applications. | Cao Wu Jing Wang Xiaohang Zhang Lixing Kang Xun Cao Yongyi Zhang Yutao Niu Yingying Yu Huili Fu Zongjie Shen Kunjie Wu Zhenzhong Yong Jingyun Zou Bin Wang Zhou Chen Zhengpeng Yang Qingwen Li | 2023 | Nano-Micro Letters2023,15,1: | 2 |

| 16 | Least trace extended set-membership filter显示文摘To improve the consistency of estimation result, a least-trace extended set-membership filter (LTESMF) is presented for a class of nonlinear stochastic systems, which has linear output and unknown- but-bounded noise. Feedback technique is used instead of the intersection of ellipsoid-sets in the measurement update. The feedback parameter is optimized in order to minimize the trace of error bounded ellipsoid’s envelop matrix. A new stability analysis method was developed to prove the stochastic system’s stability by using the convergence of some measurement of the error bounded ellipsoid. Analysis result shows that the estimation error of LTESMF will converge to a bounded area. A simulation of SINS/GPS integrated alignment with large misalignment angles is conducted. The results demonstrate that the convergence speed and the consistency of LTESMF are much better than those of extended Kalman filter (EKF), in addition the steady estimation precision and computational complexity are close to that of EKF. | HUANG Yi , CHEN ZongJi & WEI Chen National Key Laboratory of Science and Technology on Integrated Control Technology, School of Automation Science and Electric Engineering, Beihang University, Beijing 100083, China | 2010 | Science China(Information Sciences)2010,53,2: | 2 |
| 17 | Hydrogen Bonding-Assisted Synthesis of Silica/Oxidized Mesocarbon Microbeads Encapsulated in Amorphous Carbon as Stable Anode for Optimized/Enhanced Lithium Storage显示文摘The practical application of silica-based composites as an alternative to commercial graphite anode materials is hampered by their large volumetric expansion,poor conductivity,and low Coulombic efficiency.In this work,a novel silica/oxidized mesocarbon microbead/amorphous carbon(SiO2/O’MCMB/C)hierarchical structure in which SiO2 is sandwiched between spherical graphite and amorphous carbon shell was succes sfully fabricated through hydrogen bonding-assisted self-assembly and post-carbon coating method.The obtained three-layer hierarchical structure effectively accommodates the volumetric expansion of SiO2 and significantly enhances the electronic conductivity of composite materials.Moreover,the outer layer of amorphous carbon effectively increases the diffusion rate of lithium ions and promotes the formation of stable SEI film.As a result,the SiO2/O’MCMB/C composite exhibits superior electrochemical performance with a reversible capacity of 459.5 mA h/g in the first cycle,and the corresponding Coulombic efficiency is 62.8%.After 300 cycles,the capacity climbs to around 600 mA h/g.This synthetic route provides an efficient method for preparing SiO2 supported on graphite with excellent electrochemical performance,which is likely to promote its commercial applications. | Zongjie Cao Huitian Liu Wenlong Huang Peng Chen Yuansheng Liu Yu Yu Zhongqiang Shan Shuxian Meng | 2020 | Transactions of Tianjin University2020,26,1: | 2 |
| 18 | MULTI-REGION SEGMENTATION OF SAR IMAGE BY A MULTIPHASE LEVEL SET APPROACH显示文摘In this letter,a multiphase level set approach unifying region and boundary-based infor-mation for multi-region segmentation of Synthetic Aperture Radar(SAR)image is presented.Anenergy functional that is applicable for SAR image segmentation is defined.It consists of two termsdescribing the local statistic characteristics and the gradient characteristics of SAR image respectively.A multiphase level set model that explicitly describes the different regions in one image is proposed.The purpose of such a multiphase model is not only to simplify the way of denoting multi-region by levelset but also to guarantee the accuracy of segmentation.According to the presented multiphase model,the curve evolution equations with respect to edge curves are deduced.The multi-region segmentationis implemented by the numeric solution of the partial differential equations.The performance of theapproach is verified by both simulation and real SAR images.The experiments show that the proposedalgorithm reduces the speckle effect on segmentation and increases the boundary alignment accuracy,thus correctly divides the multi-region SAR image into different homogenous regions. | Fu Yusheng Cao Zongjie Pi Yiming | 2008 | Journal of Electronics(China)2008,25,4: | 2 |
| 19 | Rapid and accurate detection of African swine fever virus by DNA endonuclease-targeted CRISPR trans reporter assay显示文摘The first case of African swine fever(ASF)outbreak in China was reported in a suburban pig farm in Shenyang in 2018.Since then,the rapid spread and extension of ASF has become the most serious threat fo r the swine industry.Therefore,rapid and accurate detection of African swine fever virus(ASFV)is essential to provide effective strategies to control the disease.In this study,we developed a rapid and accurate ASFV-detection method based on the DNA endonuclease-targeted CRISPR trans reporter(DETECTR)assay.By com bining recombinase polymerase am plification w ith CRISPR-Cas12a proteins,the DETECTR assay dem onstrated a m inim um detection lim it of eight copies with no cross reactivity with other swine viruses.Clinical blood samples were detected by DETECTR assay and showed 100%(30/30)agreement w ith real-tim e polymerase chain reaction assay.The rapid and accurate detection of ASFV may facilitate tim ely eradication measures and strict sanitary procedures to control and prevent the spread of ASF. | Zongjie Li Jianchao Wei Di Di Xin Wang Chenxi Li Beibei Li Yafeng Qiu Ke Liu Feng Gu Minglong Tong Shuiming Wang Xiaodong Wu Zhiyong Ma | 2020 | Acta Biochimica et Biophysica Sinica2020,52,12: | 2 |
| 20 | Combined indirect and direct method for adaptive fuzzy output feedback control of nonlinear system显示文摘A novel control method for a general class of nonlinear systems using fuzzy logic systems (FLSs) is presertted. Indirect and direct methods are combined to design the adaptive fuzzy output feedback controller and a high-gain observer is used to estimate the derivatives of the system output. The closed-loop system is proven to be semiglobally uniformly ultimately bounded. In addition, it is shown that if the approximation accuracy of the fuzzy logic system is high enough and the observer gain is chosen sufficiently large, an arbitrarily small tracking error can be achieved. Simulation results verify the effectiveness of the newly designed scheme and the theoretical discussion. | Ding Quanxin Chen Haitong Jiang Changsheng Chen Zongji | 2007 | Journal of Systems Engineering and Electronics2007,18,1: | 2 |
