The galactic center is a rich and complex source of infrared radiation in which interesting phenomena occur in great variety . 銀河系中心是一個紅外輻射豐富和結(jié)構(gòu)復(fù)雜的源,在那里發(fā)生著各種各樣的有趣現(xiàn)象。
During the past year , fda has carefully weighed several complex sources of data , some which show conflicting results , related to the risk of chest pain , heart attacks and heart - related deaths , and deaths from any cause in patients treated with avandia 過去幾年里, fda曾經(jīng)仔細(xì)地斟酌了幾份復(fù)雜的資料,涉及到用文迪雅治療的病人,胸痛,心肌梗塞,心臟有關(guān)的死亡,和其他原因的死亡,有些結(jié)果相互矛盾
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 基于射線理論的高頻漸近射束(復(fù)射束、高斯射束)疊加方法,以窗口富里葉變換( wft )以及小波變換為基礎(chǔ)的局部相位-空間域(小波束域)波場外推方法等相繼產(chǎn)生。
