| 1 | 软件工程专业物联网及嵌入式系统方向教学研究(英文)显示文摘当前,软件工程专业如何适应物联网及嵌入式系统领域的巨大需求,是一个亟待解决的问题。基于该问题,本文提出一个新方法进行该专业的课程安排及学习计划。首先,结合物联网基础设施技术,在软件工程教学中融入物联网及嵌入式系统的教学内容,分析学生惧怕物联网及嵌入式系统发展的原因;然后,提出循序渐进的由低级别嵌入式系统开发到高级别应用软件开发的学习路径;最后,分别剖析物联网及嵌入式系统方向的就业选择和职业规划。 | Ce Zhang Dianhui Chu Fanchao Meng Zhipeng Chen Xinsheng Wang Weigong Lyu | 2016 | 计算机教育2016，，8： | 4 |
| 2 | A Review of Atmospheric Electricity Research in China from 2019 to 2022显示文摘Atmospheric electricity is composed of a series of electric phenomena in the atmosphere.Significant advances in atmospheric electricity research conducted in China have been achieved in recent years.In this paper,the research progress on atmospheric electricity achieved in China during 2019-22 is reviewed focusing on the following aspects:(1)lightning detection and location techniques,(2)thunderstorm electricity,(3)lightning forecasting methods and techniques,(4)physical processes of lightning discharge,(5)high energy emissions and effects of thunderstorms on the upper atmosphere,and(6)the effect of aerosol on lightning. | Weitao LYU Dong ZHENG Yang ZHANG Wen YAO Rubin JIANG Shanfeng YUAN Dongxia LIU Fanchao LYU Baoyou ZHU Gaopeng LU Qilin ZHANG Yongbo TAN Xuejuan WANG Yakun LIU Shaodong CHEN Lyuwen CHEN Qingyong LI Yijun ZHANG | 2023 | Advances in Atmospheric Sciences2023，40，8： | 0 |
| 3 | Development of a low-frequency magnetic lightning mapping system(LFM-LMS)in North China:validation and preliminary results显示文摘A low-frequency magnetic lightning mapping system(LFM-LMS)was built during the SHAndong Triggered Lightning Experiment(SHATLE),based on continuous measurements of magnetic field radiation from lightning.The hardware and source-mapping techniques used by the LFM-LMS were introduced;both Monte Carlo simulations and the observation of rocket-triggered lightning examples were employed to examine the location accuracy and detection effectiveness of the LFM-LMS.We estimated that the system’s location accuracy about 100−200 m horizontally and~200 m vertically.A natural intra-cloud lightning flash and a rocket-triggered lightning flash,both with intricate structures and discharging processes,were examined using the three-dimensional mapping results.The progressing path of negative lightning leaders is usually well-defined,and its propagation speed is estimated to be(0.5−1.4)×10^(6)m/s.In summary,the LFM-LMS can reconstruct the three-dimensional morphology of lightning flashes;this technology provides a efficient method for investigating the characteristics of lightning development,as well as the overall electrical strucuture of thunderstorms. | Xiao Li GaoPeng Lu FanChao Lyu HongBo Zhang Kainat Qamar RuBin Jiang | 2023 | Earth and Planetary Physics2023，7，4： | 0 |
| 4 | Recent observations and research progresses of terrestrial gamma-ray flashes during thunderstorms显示文摘Terrestrial gamma-ray flashes(TGFs)are high-energy emissions in thunderstorms that were discovered first by satellite-based and then by ground-based gamma-ray detectors with photon energy up to tens of Me V.TGFs are a natural highenergy phenomenon associated with lightning discharges that frequently occur during thunderstorms.However,their production mechanisms and associated processes are still unclear.TGF studies have already been a research spotlight in the atmospheric electricity and high-energy atmosphere research areas.In this paper,we review recent research progresses on TGF studies in the past decade,including TGF detection,the relationship between TGFs and lightning processes,and thunderstorm activities.Several unsolved important scientific questions are discussed.Results suggest that upward TGFs observed by satellite-based detectors are closely connected with the development of in-cloud upward negative leaders.They are usually generated in milliseconds of the initiation of upward negative leaders and may produce a kind of distinct radio emissions because of the generation and propagation of huge amounts of high-energy electrons.By contrast,its counterpart,i.e.,downward TGFs observed by ground-based gamma-ray detectors,is associated with different types of lightning processes,such as downward negative or upward positive leaders,the initial continuing current stage of rocket-triggered lightning flashes return stroke processes.Because of limited observations,how these downward TGFs are generated is still unclear.Benefiting from the development of state-of-the-art instruments with high temporal and spatial resolutions,new insights into the processes and mechanisms of TGFs will be achieved with coordinated observations from satellite-based and ground-based measurements. | Fanchao LYU Yijun ZHANG Gaopeng LU Baoyou ZHU Hongbo ZHANG Wei XU Shaolin XIONG Weitao LYU | 2023 | Science China Earth Sciences2023，66，3： | 0 |
