Crack initiation ahead of piled-up of dislocations emitted from a mode Ⅱ blunt crackCaifu Qian, Wuyang Chu, and Lijie QiaoDepartment of Mechanical Engineering, Beijing University of Chemical... tests in a transmission electron microscope (TEM) show that dislocations emitted from a mode II crack tip will form a inverse piled-up group after equilibrium or a double piled-up group when they meet......
;Hydrogen distribution and content in diamond films deposited by DC arcjet under gas recycling mode was evaluated by nuclear reaction analysis (NRA). The films were characterized using scanning electron......

Modified AlAs/GaAs Double Barrier Quantum Resonant Tunneling Diodes Grown by AP-MOCVD任红文,黄柏标,徐现刚,刘士文,蒋民华,于淑琴摘 要:<正> The MOCVD growth of modified AlAs/GaAs double barrier resonant tunneling diodes(DBRTD)withan A1GaAs chair was reported.The resonances to the first excited states were obtained.The peak-to-valley cur-rent ratio(PVCR)is 1.3 at 77K,room......
">The influence of temperature on calcareous deposits formed under galvanostatic polarization mode was studied.The deposition was monitored by electrochemical impedance spectrum,and a supplementary loop in Nyquist......
Relationship between crystal growth mode, preferred orientation and magnetostriction of (Tb0.3Dy0.7)Fe1.95 alloys张世荣,李扩社,于敦波,李勇胜,杨红川,李红卫,涂赣峰摘 要:The relationship between crystal growth mode, preferred orientation and magnetostrictive properties of (Tb0.3Dy0.7)Fe1.95 alloys was investigated at different directional solidification rates. The results showed......
Optimal air-supply mode of hybrid system with radiant cooling and dedicated outdoor airDING Yan(丁研), TIAN Zhe(田喆), ZHU Neng(朱能) (School of Environmental Science and Engineering, Tianjin University.... Indoor air quality will be improved by the dedicated outdoor air system (DOAS) and indoor thermal comfort can be enhanced by the radiant cooling system (RCS). The optimal air-supply mode......
on rotating disk affect the atomization mechanism and results remarkably. The main disintegration mode of melt is the breakup type of liquid film, which depends on the film instability and the atomization ability of the rotating disk. On the other hand, the mean powder size relates closely to the film thickness. The powder size distribution is mainly controlled by the atomization mode......
J. Cent. South Univ. (2018) 25: 2462-2471 DOI: https://doi.org/10.1007/s11771-018-3929-y A new approach for selecting best development face ventilation mode based on G1-coefficient of variation.... In the case study, an appropriate evaluation index system was established to determine the evaluation value of each ventilation mode. Then the proposed approach was used to select the best......
