and why this treatment should be as itis was explained. The FDTD method was developed to compute the low-frequencyelectromagnetic fields in the metal instead of the traditional high-frequency ones as itwas......
modified molten-pool geometry and the synchronously high-frequency re-melting of the molten pool contribute to the formation of singlecrystal-like structure.This work reports a new route to promote......
to calculate shallow S-wave velocity structure effectively. But in the large time-space sampling seismic data, the high-frequency signal components are usually aliased seriously, or even exceeding... in the high-frequency section. The interpolation of Rayleigh waves was accomplished based on wavelet transform (WT). According to the characteristic of linear seismic event, linear normal moveout (LNMO......
, transmission coefficient of the high-frequency region decreases, and the transmission spectrum moves to the lower frequency region. Meanwhile, with the increase of the ratio of atomic mass, the thermal... squared, the thermal conductivity shows a slowly increasing trend in the way of steps with the increase of frequency squared, and tends to be a certain value in the high-frequency region. Key words......
coefficient in high-frequency region is higher than that in low-frequency region. The sound absorption property of the sample prepared by the former method is better than that of the sample prepared by the latter method in high-frequency region, which is due to the decrease of connected space between adjacent holes in counter-gravity infiltration casting. The sound absorption coefficient of open......
Influence of heat treatment on high frequency soft magnetic properties of Finemet amorphous alloy YANG Sha(杨 沙)1, 2, CHEN Bo-qu(陈伯渠) 1, 2, YAN Biao(严 彪) 1, 2, LU Wei(陆 伟) 1, 2, LONG Ling(龙..., Tongji University, Shanghai 200092, China Received 15 July 2007; accepted 10 September 2007 Abstract: In order to study high-frequency soft magnetic properties of Finemet amorphous alloy......
characteristics of ultrasonic vibration, such as acoustic streaming, cavitation and thermal effects and the high-frequency mechanical vibration characteristics, such as vigorous surface agitation, the increase of the nucleation induced by falling off solid particles formed on the crucible wall. The melt is IUV treated, the combined action of ultrasonic and high-frequency mechanical vibration are rather than......
">Non-oriented silicon steels containing different mass fractions of lanthanum were prepared using a high-frequency suspended furnace.Microstructures were observed by a metallographic microscope......
and electrical properties of Pd-Ru binary alloy was investigated in this work. The alloys were prepared in a vacuum high-frequency melting furnace. X-ray diffraction and metallographic microscope were employed......
