2The geometric factor of high energy protons detector on FY-3 satellite显示文摘Geometric factor is the key parameter for inversion of particle spectrum in space particle detection. Traditional geometric factor is obtained through the method of numerical calculation with the actual structure of the detector as the input condition. The degree of accuracy for data inversion is reduced since traditional geometric factor fails to take into account the physical process of interaction between the particle and substance as well as the influence of factors such as the particle interference between different energy channels on the measurement result. Here we propose an improved geometrical factor calculation method, the concept of which is to conduct actual structural modelling of the detector in the GEANT4 program, consider the process of interaction between the particle and substance, obtain the response function of the detector to particles of different energy channels through the method of Monte Carlo simulation, calculate the influence of contaminated particle on the geometrical factor, and finally get the geometrical factors for different energy channels of the detector. The imrpoved geometrical factor obtained through the method has carried out inversion for the data of high energy protons detector on China's FY-3 satellite, the energy spectrum after which is more in line with the power law distribution recognized by space physics. The comparison with the measured result of POES satellite indicates that the FY-3 satellite data are in good accordance with the satellite data, which shows the method may effectively improve the quality of data inversion.ZHANG ShenYi ZHANG XianGuo WANG ChuiQin SHEN GuoHong JIN Tao ZHANG BinQuan SUN YueQiang ZHU GuangWu LIANG JinBao ZHANG XiaoXin LI JiaWei HUANG Cong HAN Ying 2014Science China Earth Sciences2014,57,10:6
3Super solar particle event around AD775 was found显示文摘A rapid radiocarbon14C increase of 120/00in AD774–775 has been reported in cedar and oak tree rings.So far,the origin of the14C increase is still uncertain and the possible origin is either supernova or solar particle event.The most possible origin of14C increase is strong solar flares and Coronal Mass Ejections(CMEs)with strong particles emission.Comprehensive approaches to identify the strong historical solar particle events based on the rapid14C/10Be increase in tree/coral rings and ice cores,long duration strong auroras and geomagnetic storms are introduced.Evidence of the super auroras in AD775 was first found in a Chinese Chronicles Jiutangshu and it supports the views that the rapid14C increase and strong auroras around AD775 are most possibly caused by strong solar storms with intense particles emission.It was identified that the solar event around AD775 would be the strongest solar particle event in the past 11400 years.The discovery is significant for the research on the history of solar activities,space weather and forecast,radiation of solar energetic particles and protection.Dazhuang Zhou Chi Wang Binquan Zhang Shenyi Zhang Ping Zhou Yueqiang Sun Jinbao Liang Guangwu Zhu Ji Wu 2014Chinese Science Bulletin2014,59,22:4

5Proton belt variations traced back to Fengyun-1C satellite observations显示文摘We used historical data to trace trapped protons observed by the Fengyun-1C(FY-1C)satellite at low Earth orbits(~800 km)and chose data at 5–10 MeV,10–40 MeV,40–100 MeV,and^100–300 MeV from 25 March to 18 April 2000 to analyze the proton variations.Only one isolated strong storm was associated with a solar proton event during this period,and there was no influence from previous proton variations.Complex dynamic phenomena of proton trapping and loss were affected by this disturbance differently depending on the energy and L location.The flux of 5–10 MeV protons increased and created new trapping with a maximum at L^2.0,and the peak flux was significantly higher than that at the center of the South Atlantic Anomaly.However,at higher L,the flux showed obvious loss,with retreat of the outer boundary from L^2.7 to L^2.5.The increase in the 10–40 MeV proton flux was similar to that of the 5–10 MeV flux;however,the peak flux intensity was lower than that at the center of the South Atlantic Anomaly.The loss of the 10–40 MeV proton flux was closer to the Earth side,and the outer boundary was reduced from L^2.3 to L^2.25.For the higher energy protons of 40–100 MeV and 100–300 MeV,no new trapping was found.Loss of the 40–100 MeV protons was observed,and the outer boundary shifted from L^2.0 to L^1.9.Loss was not obvious for the 100–400 MeV protons,which were distributed within L<1.8.New proton trapping was more likely to be created at lower energy in the region of solar proton injection by the strong magnetic storm,whereas loss occurred in a wide energy range and reduced the outer boundary on the Earth side.Similar dynamic changes were observed by the NOAA-15 satellite in the same period,but the FY-1C satellite observed more complex changes in lower energy protons.These results revealed that the dynamic behavior of protons with different L-shells was due to differences in the pitch angle.Possible mechanisms related to new trapping and loss are also discussed.These mechanisms are very important for understanding the behavior of the proton belt in the coming solar cycle.ChunQin Wang Zheng Chang XiaoXin Zhang GuoHong Shen ShenYi Zhang YueQiang Sun JiaWei Li Tao Jing HuanXin Zhang Ying Sun BinQuan Zhang 2020Earth and Planetary Physics2020,4,6:1

7Radio Frequency Fingerprint-Based Satellite TT&C Ground Station Identification Method显示文摘This study presents a radio frequency(RF)fingerprint identification method combining a convolutional neural network(CNN)and gated recurrent unit(GRU)network to identify measurement and control signals.The proposed algorithm(CNN-GRU)uses a convolutional layer to extract the IQ-related learning timing features.A GRU network extracts timing features at a deeper level before outputting the final identification results.The number of parameters and the algorithm’s complexity are reduced by optimizing the convolutional layer structure and replacing multiple fully-connected layers with gated cyclic units.Simulation experiments show that the algorithm achieves an average identification accuracy of 84.74% at a -10 dB to 20 dB signal-to-noise ratio(SNR)with fewer parameters and less computation than a network model with the same identification rate in a software radio dataset containing multiple USRP X310s from the same manufacturer,with fewer parameters and less computation than a network model with the same identification rate.The algorithm is used to identify measurement and control signals and ensure the security of the measurement and control link with theoretical and engineering applications.Xiaogang Tang Junhao Feng Binquan Zhang Hao Huan 2023Journal of Beijing Institute of Technology2023,32,1:0

9Analysis of the Architectural Design Talent Development Direction by Investigating the Employment Status of Architectural Design Graduates显示文摘Based on a comprehensive investigation of the employment status of architectural design graduates at a certain university,this paper analyzes the correctness of the talent development direction of architectural design in hopes of pro-viding a valuable reference for further teaching reform and strengthening school-enterprise collaboration.The research re-sults show that architectural design is the main choice of graduates,accounting for as high as 63%,and traditional architec-tural design skills continue to be in demand in the market.Employment in fields such as interior design,BIM design,and green architecture is also included.The distribution of job positions for graduates is mainly in the areas of scheme design assistants and construction drawing design,requiring software operation,communication,scheme design,and construction drawing skills.This paper also proposes talent development measures such as optimizing the curriculum,strengthening faculty construction,and deepening school-enterprise collaboration,in order to improve the quality of talent development and the competitiveness of graduates.Cuicui Qin Lijuan Xie Qiliang Yu Guanhong Chen Binquan Zhang Yani Gao 2023Journal of Architectural Research and Development2023,7,6:0
