| 1 | Combining sum-difference and auxiliary beams for adaptive monopulse in jamming显示文摘Only in the presence of sidelobe jamming(SLJ),can the conventional adaptive monopulse technique null the jamming effectively and maintain the monopulse angle estimation accuracy simultaneously.While mainlobe jamming(MLJ) exists,the mainlobe of adaptive pattern will subject to serious distortion,which results in a failure of detecting and tracking targets by monopulse technique.Therefore,a monopulse angle estimation algorithm based on combining sum-difference beam and auxiliary beam is presented.This algorithm utilizes both high gain difference beams and high gain auxiliary beams for cancelling the mainlobe jammer and multiple sidelobe jammers(SLJs) while keeping an adaptive monopulse ratio.Theoretical analysis and simulation results indicate that the serious invalidation of monopulse technique in MLJ and SLJs scenarios is resolved well,which improves the monopulse angle accuracy greatly.Furthermore,the proposed algorithm is of simple implementation and low computational complexity. | Rongfeng Li Can Rao Lingyan Dai Yongliang Wang | 2013 | Journal of Systems Engineering and Electronics2013，24，3： | 13 |
| 2 | A preliminary study on the volcanic intrusive complex type beryllium metallogenic belt from the southeast coast of China显示文摘Beryllium(Be)is one of the unsubstitutable key metals in strategic emerging industries and national defense industries,mainly originating from volcanogenic Be deposits.Thus,volcanogenic Be deposits have become important research objects of key metal deposits,with a focus on their occurrence,metallogenic mechanism,and resource distribution.In the southeast coast of China,the Late Mesozoic volcanic intrusive complex has a good Be metallogenic background,and strong Be mineralization occurs in some areas.Field geological investigation and analyses of samples from Southeast Zhejiang as well as Northeast and Southeast Fujian indicate that Be mineralization in the southeast coast of China is closely related to the hydrothermal processes in the volcanic intrusive complex.In Southeast Zhejiang,Be ore in the Qingtian area mainly occurs in granite porphyry,with the Be content reaching 939 ppm,while strong Be mineralization from Zhangji rhyolite porphyry in the Pingyang area contains up to 11400 ppm Be.In Xiapu County,Northeastern Fujian,the Dawan Be deposit is characterized by constituents of helvite and beryl.In Pinghe County,Southeastern Fujian,the Fulishi Be ore is a quartz vein beryl-type ore.These results suggest that the volcanic intrusive complex area in the southeast coast of China has a wide range of Be mineralization and better Be metallogenic potential,and it is expected to become an important Be metallogenic belt in China.Thus,we should thoroughly investigate the Be resources of granite porphyry,rhyolite porphyry,quartz porphyry,and quartz vein in this volcanic rock area,which can provide a theoretical basis for the exploration and guiding prospecting of volcanic intrusive complex Be deposits. | Can RAO Rucheng WANG Fuyuan WU Xudong CHE Xiaofeng LI Qi WANG Zhiqi ZHANG Runqiu WU | 2022 | Science China Earth Sciences2022，65，8： | 2 |

| 5 | Chronic spinal cord injury repair by NT3-chitosan only occurs after clearance of the lesion scar显示文摘Spinal cord injury(SCI)is a severe damage usually leading to limb dysesthesia,motor dysfunction,and other physiological disability.We have previously shown that NT3-chitosan could trigger an acute SCI repairment in rats and non-human primates.Due to the negative effect of inhibitory molecules in glial scar on axonal regeneration,however,the role of NT3-chitosan in the treatment of chronic SCI remains unclear.Compared with the fresh wound of acute SCI,how to handle the lesion core and glial scars is a major issue related to chronic-SCI repair.Here we report,in a chronic complete SCI rat model,establishment of magnetic resonancediffusion tensor imaging(MR-DTI)methods to monitor spatial and temporal changes of the lesion area,which matched well with anatomical analyses.Clearance of the lesion core via suction of cystic tissues and trimming of solid scar tissues before introducing NT3-chitosan using either a rigid tubular scaffold or a soft gel form led to robust neural regeneration,which interconnected the severed ascending and descending axons and accompanied with electrophysiological and motor functional recovery.In contrast,cystic tissue extraction without scar trimming followed by NT3-chitosan injection,resulted in little,if any regeneration.Taken together,after lesion core clearance,NT3-chitosan can be used to enable chronic-SCI repair and MR-DTI-based mapping of lesion area and monitoring of ongoing regeneration can potentially be implemented in clinical studies for subacute/chronic-SCI repair. | Can Zhao Jia-Sheng Rao Hongmei Duan Peng Hao Junkui Shang Yubo Fan Wen Zhao Yudan Gao Zhaoyang Yang Yi Eve Sun Xiaoguang Li | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 0 |
| 6 | Recent advances in electrochemical performance of Mg-based electrochemical energy storage materials in supercapacitors:Enhancement and mechanism显示文摘The application of Mg-based electrochemical energy storage materials in high performance supercapacitors is an essential step to promote the exploitation and utilization of magnesium resources in the field of energy storage.Unfortunately,the inherent chemical properties of magnesium lead to poor cycling stability and electrochemical reactivity,which seriously limit the application of Mg-based materials in supercapacitors.Herein,in this review,more than 70 research papers published in recent 10 years were collected and analyzed.Some representative research works were selected,and the results of various regulative strategies to improve the electrochemical performance of Mg-based materials were discussed.The effects of various regulative strategies(such as constructing nanostructures,synthesizing composites,defect engineering,and binder-free synthesis,etc.)on the electrochemical performance and their mechanism are demonstrated using spinelstructured MgX_(2)O_(4) and layered structured Mg-X-LDHs as examples.In addition,the application of magnesium oxide and magnesium hydroxide in electrode materials,MXene's solid spacers and hard templates are introduced.Finally,the challenges and outlooks of Mg-based electrochemical energy storage materials in high performance supercapacitors are also discussed. | Yuntao Xiao Xinfang Zhang Can Wang Jinsong Rao Yuxin Zhang | 2024 | Journal of Magnesium and Alloys2024，12，1： | 0 |
| 7 | Loss Analysis of Magnetic Gear with Slotted in Magnetic Modulation Ring显示文摘In order to improve the operation efficiency of coaxial magnetic gear(CMG),in this paper,a CMG model with slotted in magnetic modulation ring is proposed.In this model,the permanent magnets(PMs)of internal and external rotors are distributed in Halbach array,the inner rotor PMs are equally divided into 3 small pieces,and the outer rotor PMs are equally divided into 2 small pieces.At the same time,the static magnetic modulation ring iron blocks are slotted,each iron block has 3 slots,the width of the slot is 0.4°,and the depth of the single side slot is 1mm.Finally,a two-dimensional model is established,and the eddy current loss and iron loss of the model are optimized,compared with the conventional CMG model,it is found that the changed pattern can increase the internal and external output torque by 4%and 4.12%,respectively.The eddy current loss is reduced by 66.57%,and the iron loss is reduced by 8.9%,which significantly improve the operation efficiency of the CMG. | Can Tan Wei Liu Yingying Rao Weizhao Tang Libing Jing | 2023 | CES Transactions on Electrical Machines and Systems2023，7，1： | 0 |
