高频渐近 meaning in English

high-frequency asymptote

Advanced mathematical technologies , especially the newly developed wavelet transform and the frame theory , provide a solid foundation for such an effort . the ray - theory based beam - summation method , such as the complex source - generated beam and the gaussian beam methods , and the local phase - space domain ( beamlet domain ) wave field extrapolation methods employing windowed fourier transform ( wft ) or wavelet transform are proposed consequently
基于射线理论的高频渐近射束(复射束、高斯射束)叠加方法，以窗口富里叶变换( wft )以及小波变换为基础的局部相位-空间域(小波束域)波场外推方法等相继产生。
