) and HRSEM (Hitachi S-4160), respectively. IR spectra were recorded in the wave length range of 400-4000 cm-1 with a resolution of 4 cm-1, using Bruker tensor 27 FTIR spectrometer with RT-DIATGS detector......
in another wave of vigorous development since late 1970s. With increasing demands for much larger wind farms, the problems of horizontal axis wind turbine (HAWT) are highlighted through the application, some......
is displayed in Fig. 10. The granules persistently keep close contact with each other to transmit the internal momentum in the shear process. The elastic wave caused by the contact spreads at the sound......
and has strong robustness. We used the following test conditions: the moment of inertia changes from 1.48×10-2 kg·m2 to 7.4×10-3 kg·m2, and the given speed is a sine wave whose amplitude and period......
is set as a (9±2) mm square wave, and the desired levitation gap △2r is set as 9 mm without variation. When the desired levitation gap △1r is varied, the control voltage drives the levitation gap errors......
et al [8] combined seismic wave equation depth imaging and GGT data inversion, and was found to resolve the base of salt in the Gulf of Mexico much better than Kirchhoff depth imaging alone......
