Power laws in the frequency and wave-number spectra of parameters such as horizontal wind have been widely studied, but the frequency spectrum of mountain waves remains, by comparison, poorly understood. It is found that errors arising from the VHF radar measurement technique are not sufficient to...
IN the course of a research on the heating effects of radiation of wave-lengths 10 to 200 metres, it was found that for a given wave-length there is a maximum heating effect produced in a medium the specific conductivity and dielectric constant of which are connected with the frequency by ...
The meaning of SPECTRUM is a continuum of color formed when a beam of white light is dispersed (as by passage through a prism) so that its component wavelengths are arranged in order. How to use spectrum in a sentence.
spectrum和spectra的区别是形式不同，侧重点不同，读音不同。一、形式不同 1、spectrum：spectrum是原形。2、spectra：spectra是spectrum的复数形式之一。二、侧重点不同 1、spectrum：spectrum侧重于单一的，意思是谱，光谱，声谱，波谱。示例：The individual colours within the light spectrum are believed ...
First of all , if we choose triangular wave as initial wave The corresponding power spectrum are shown below We can see there are several peaks in the power spectrum, with the increasing of frequency, the peakvalue get smaller. Then we change the excited point. If the string is excited fro...
and the representation may be reasonable, for the given conditions, except for wave properties dependent on the high frequency part of the spectrum such as the variance of slope and curvature, in which case a high frequency cut-off and a different representation for the capillary waves should pe...
