1Study of charge structure and radiation characteristic of intracloud discharge in thunderstorms of Qinghai-Tibet Plateau显示文摘The comprehensive observations on lightning discharges were conducted in Naqu area of Qinghai-Tibet Plateau in summer of 2002. The electric structures of thunderstorms and the characteristics of lightning discharges at initial stage were analyzed by using the observation data. The results show that most of intracloud (IC) lightning flashes were polarities inverted in thunderstorms with tripole electric charge structure and occurred between negative charge region located in the middle of the thunderstorm and positive charge region located at the bottom of the thunderstorm. The radiation characteristics of discharge processes in cloud with longer lasting time involved in Cloud-to-Ground (CG) lightning flashes were similar to that of IC discharges.A lot of radiation pulses were produced in these discharge processes. Because the IC discharges took place at the bottom of thundercloud and were near the ground, they may produce more serious damage to equipment on the ground therefore should not be neglected in lightning protection.ZHAGN Yijun DONG Wansheng ZHAO Yang ZHANG Guangshu ZHANG Hongfa CHEN Chengpin ZHANG Tong 2004Science China Earth Sciences2004,47,z1:16
2Electric field soundings and the charge structure within an isolated thunderstorm显示文摘A strong electric (E) field sounding system was designed to measure the vertical component of the E-fields, temperature, relative humidity and GPS data along the sounding path. In the summer of 2008, in situ measurements of E-field inside the thunderstorms were conducted in Pingliang, Gansu Provience, with the cooperation of an X-band weather radar. One E-field profile inside a thunderstorm was successfully acquired. The sounding data indicated four charge layers along the sounding trajectory, three in-side the thuderstorm and one at its lower boundary. The lower cloud boundary charge layer was negative, acting as a screening layer, and laid between 4.3 to 4.5 km a.s.l. The lower positive charge center (LPCC) existed between 4.5–5.3 km a.s.l. (from 3°C to -2°C); the main negative charge area was present between 5.4–6.6 km a.s.l. (-3°C to -10°C); the upper positive charge layer was between 6.7–7.2 km a.s.l. (-11°C to -14°C). The results support the tripole charge structure inside thunderstorms (above 0°C isotherm altitude), but the LPCC is much larger-than-usual in Chinese inland plateau.Zhao ZhongKuo Qie XiuShu Zhang TingLong Zhang Tong Zhang HongFa Wang Yong She Yong Sun BaoLai Wang HuaiBin 2010Chinese Science Bulletin2010,55,9:8
3Wind tunnel simulation experiment and investigation on the electrification of sandstorms显示文摘Electric discharge phenomenon is often observed during the passage of sandstorms over desert regions and sometimes does great damage to human beings. Based on previous researches on the electrification of sandstorms by the scholars both at home and aboard,the authors conducted the simulation experiments on the electric fields of sandstorm-triggered creeping-saltating sand, suspending sand and watered suspending sand in the large-scale wind tunnel. According to the experimental results the electric field structure and its formation mechanism were analysed and discussed, the quantity of electric charges and electric field strengthwere measured and calculated, and finally several conclusions were drawn.QU Jianjun YAN Muhong DONG Guangrong ZHANG Hongfa ZU Ruiping TUO Wanquan ZHAO Aiguo XIAO Zhenghua LI Fang YANG Bao 2004Science China Earth Sciences2004,47,6:2

8A Broad Range Triboelectric Stiffness Sensor for Variable Inclusions Recognition显示文摘With the development of artificial intelligence,stiffness sensors are extensively utilized in various fields,and their integration with robots for automated palpation has gained significant attention.This study presents a broad range self-powered stiffness sensor based on the triboelectric nanogenerator(Stiff-TENG)for variable inclusions in soft objects detection.The Stiff-TENG employs a stacked structure comprising an indium tin oxide film,an elastic sponge,a fluorinated ethylene propylene film with a conductive ink electrode,and two acrylic pieces with a shielding layer.Through the decoupling method,the Stiff-TENG achieves stiffness detection of objects within 1.0 s.The output performance and characteristics of the TENG for different stiffness objects under 4 mm displacement are analyzed.The Stiff-TENG is successfully used to detect the heterogeneous stiffness structures,enabling effective recognition of variable inclusions in soft object,reaching a recognition accuracy of 99.7%.Furthermore,its adaptability makes it well-suited for the detection of pathological conditions within the human body,as pathological tissues often exhibit changes in the stiffness of internal organs.This research highlights the innovative applications of TENG and thereby showcases its immense potential in healthcare applications such as palpation which assesses pathological conditions based on organ stiffness.Ziyi Zhao Zhentan Quan Huaze Tang Qinghao Xu Hongfa Zhao Zihan Wang Ziwu Song Shoujie Li Ishara Dharmasena Changsheng Wu Wenbo Ding 2023Nano-Micro Letters2023,15,12:0
9Effect of GW8 Gene Editing on Appearance Quality of Erect-Panicle Type (dep1) Japonica Rice显示文摘Most high-yielding japonica rice varieties in China carry dep1,a multi-effective regulator of plant architecture and grain shape,resulting in erect panicle with short and round grain shape.However,its appearance quality needs to be improved since long-grain rice is favored by the market.GW8 is a dominant gene regulating grain shape,and its loss-of-function genotype leads to elongated grains with a better quality in appearance.MAO Ting CHEN Hongfa LI Xin LIU Yan ZHONG Shuncheng WANG Shiyu ZHAO Yizhou ZHANG Zhan NI Shanjun HUANG He LI Xu HU Shikai 2023Rice science2023,30,5:0
