| 1 | Heat exchange at air-sea interface in the South China Sea during monsoon periods in 1986显示文摘In order to explore the interaction be- tween the sea and monsoon in the South China Sea, the heat exchanges at air-sea interface during mon- soon periods in 1986 were calculated using observa- tional data. It shows that when the summer monsoon bursts and prevails over the South China Sea, the air-sea interface heat exchange is strong and the latent heat rises rapidly in the intertropical conver- gence zone and the tropic cyclone system near 20.49°N, 114.14°E. On May 24, 1986, the sensible heat became positive in the typhoon system. The heating exchange indicates that heat is transported from ocean to atmosphere, with major contribution of latent heat. When the summer monsoon prevails over the South China Sea and the weather is fine, even SST (sea surface temperature) is high, but sensible heat appears to be negative. The heat exchange indicates that heat is transported from atmosphere to ocean, with major contribution of short-wave radiation absorbed by sea surface and sensible heat. When summer monsoon is over and the northeast monsoon prevails over the South China Sea, the heat ex- change at air-sea interface is very strong. The heat- ing exchange shows that the ocean heats the at- mosphere, with major contribution of latent heat when cold air arrives at the sea surface and the sensible heat rises to positive rapidly. Therefore it can be concluded that the heat exchange at air-sea interface is different from the SST in South China Sea. Whenthe summer monsoon prevails over the South China Sea, the main trend is the ocean responding to the atmosphere. | WU Disheng FENG Weizhong XU Jianping YAN Jinghua ZHAO Xue ZHOU Shuihua ZHANG Jiwei QIAO Guanyu LIN Fu LU Boming | 2006 | Chinese Science Bulletin2006，51，19： | 0 |
| 2 | Propagation of liquid surface waves over finite graphene structured arrays of cylinders显示文摘Based on the multiple scattering method,this paper investigates a benchmark problem of the propagation of liquid surface waves over finite graphene (or honeycomb) structured arrays of cylinders.Comparing the graphene structured array with the square structured and with triangle structured arrays,it finds that the finite graphene structure can produce more complete band gaps than the other finite structures,and the finite graphene structure has less localized ability than the other finite structures. | Xuemei Liu,1,2 Yong Wei,1 Sheng Li,1 Yousheng Xu,1,Detang Lu,3 and Boming Yu 4 1) Department of Physics,Zhejiang Normal University,Jinhua 321004,Zhejiang,China 2) Hangzhou No.14 Middle School,Hangzhou 310006,China 3) Department of Modern Mechanics,University of Science and Technology of China,Hefei 230027,China 4) School of Physics,Huazhong University of Science and Technology,Wuahn 430074,China | 2011 | Theoretical & Applied Mechanics Letters2011，1，5： | 0 |
| 3 | Constructing origami power generator from one piece of electret thin film and application in AIenabled transmission line vibration monitoring显示文摘One of the crucial issues for applying electret/triboelectric power generators in the Internet of Things(IoT)is to take full advantage of specific high voltage signals and enable self-powered sensing.Therefore,inspired by Miura-origami,we present an innovative origami power generator(OPG)constructed from only one piece of electret thin film.The Miura-origami architecture realizes a generator with excellent deformability and stretchability and makes it unnecessary for any auxiliary support structure during the compress-release cycle.Various parameters of the generator are intensively investigated,including the excitation accelerations,excitation displacements,numbers of power generation units and deformation degree of the device.When stimulated with 5.0 g acceleration at 15 Hz frequency,the generator with 8 generation units can obtain an instantaneous peak-to-peak voltage and a remarkable optimum peak power of 328 V and 2152μW at 50MΩ,respectively.In addition,the regulable shape and multiple generation modes of the device greatly improve its applicability in various vibration energy collection requirements.Based on the above results,a hexagonal electret generator integrated with six-phase OPGs is developed as a“Buoy on Sky,”after which the signal waveforms generated from internal power generators are recognized with 92%accuracy through a neural network algorithm that identifies the vibration conditions of transmission lines.This work demonstrates that a fusion of origami art and energy conversion techniques can achieve a multifunctional generator design satisfying the requirements for IoT applications. | Boming Lyu Huipeng Zhou Yangyang Gao Xinhui Mao Fangzhi Li Jiyuan Zhang Dezhi Nie Wen Zeng Yonglin Lu Jin Wu Zhaoshu Yang Kai Tao | 2023 | Microsystems & Nanoengineering2023，9，4： | 0 |
