evanescent

Comprehensively discuss the issues in application , adaptive condition and performance , propose a fast arithmetic of forward modeling and depth migration in common shot gathers with one - way acoustic wave equation based on vrselrf , and verify the arithmetic by numerical simulation . concisely discuss the cause of the creation of evanescence and the problem of lateral amplitude discontinuity result from it . fourthly , use the reflectivity model , computed to describe the fracture model , with the formula of computation reflectivity based on elastic - acoustic approximation , and the wavelet model computed by the method , wavelet creation with fourier transform , we proposed , in conjunction with vrselrf wavefield extrapolation operator 第三,將頻率波數域穩定的變參考慢度rytov近似廣義屏波場延拓算子( vrselrf )應用于疊前與疊后正演模擬、疊前與疊后深度偏移,對算法應用中應注意的問題、適用范圍、性能等作了較為全面的論述;提出了基于vrselrf的單程聲波方程共炮記錄正演模擬和深度偏移快速算法,并通過數值模擬試驗對算法進行了驗證;簡要地討論了倏逝波的產生原因及其帶來的橫向振幅不連續性問題。

Very orderly and methodical he looked , with a hand on each knee , and a loud watch ticking a sonorous sermon under his flapped waistcoat , as though it pitted its gravity and longevity against the levity and evanescence of the brisk fire 他看上去十分整飭,十分拘謹。兩手放在膝蓋上,有蓋的背心口袋里一只懷表大聲滴答著,響亮地講著道,仿佛要拿它的莊重與長壽跟歡樂的火焰的輕佻與易逝作對比。

It has become an irreversible fact that we did become friends as the minute had elapsed despite its evanescence 從現在開始我們就是一分鐘的朋友,這是事實,你改變不了,因為已經過去了。
