and the calculations, pF is the Fermi momentum, and vD is the dislocation velocity. From Eqs. (3) and (4), the utility of electron wind force largely depends on the amplitude of current density......
of the influence of loading velocity on rock’s acoustic emission signal [J]. Mining Research and Development, 2010, 30(1): 12-14, 95. (in Chinese) [44] BAI Jin-wen, FENG Guo-rui, WANG Ze-hua, WANG Shan......
velocity and pollutant emissions of the gasoline components and its surrogate fuels: A review [J]. Fuel, 2020, 269: 117451. DOI: 10.1016/j.fuel.2020.117451. [2] HAN Wei-wei, ZHOU Yong, ZHU Ting, CHU......
velocity, is the strain rate, L0 is the gauge length of the specimen, and t is the tensile time. The tensile specimens with a gauge length of 25 mm and a width of 6 mm were cut using......
阶段即第三阶段. 图15 典型亚临界扩展速度与应力强度因子关系曲线 Fig. 15 Typical curve of relation between stress intensity factor and crack velocity for subcritical crack growth 3.1 岩石亚临界裂纹研究进展 目前,对于裂纹扩展速率的测量主要存......
generation. For the catalytic test, the mole ratio of oxygen to methanol was controlled at 0.5. The gas hourly space velocity (GHSV) and weight hourly space velocity (WHSV) were controlled at 60000 h-1......
Trans. Nonferrous Met. Soc. China 27(2017) 2113-2136 Friction stir welding of aluminum to copper-An overview Nidhi SHARMA, Zahid A. KHAN, Arshad Noor SIDDIQUEE Department of Mechanical Engineering, Jamia Millia Islamia, New Delhi, India Received 12 September 2016; accepted 20 January 2017 Abstract: ......
) and SCC velocity of over-aged alloys appeared to be mainly controlled by the Cu content of the grain boundary precipitates: lower Cu contents result in larger differences in potential between......
how flow influenced erosive-corrosive wear, as shown in Fig. 3 [17]. The effects of geometry, flow velocity, material, melt temperature, and exposure time on wear can be evaluated. However......
direction was then increased by applying a constant velocity of 0.05 m/s, and the stresses of the other two boundaries remain constant, as shown in Fig. 6(a). This was repeated in each of the three......
