  1. 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運算元（ vrselrf ）應用於疊前與疊后正演模擬、疊前與疊后深度偏移，對演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；提出了基於vrselrf的單程聲波方程共炮記錄正演模擬和深度偏移快速演算法，並通過數值模擬試驗對演算法進行了驗證；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。
  2. A coherent electromagnetic pulse in the range between the far - infrared and microwave region is used as a detection source. the amplitude of the wave is recorded by electro - optical or photoconductive sampling. after fast fourier transform, the amplitude and phase of the wave is given, then the complex refractive index standing for the absorption and dispersion of the material in thz region is extracted

    Thz （ 10 ~ （ 12 ） hz ）時域光譜技術是20世紀90年代發展起來的一種新型的光譜測量技術，它使用頻率介於遠紅外和微波之間的相干電磁輻射脈沖作為探測源，利用電光取樣或光電導取樣的方法直接記錄thz輻射電場的振幅時間波形，通過傅立葉變換得到測量信號振幅和相位的光譜分佈，進而獲得材料在thz波段的復介電常數，即色散及吸收等信息。
  3. At present the identification signal of rolling bearing is based on analog monitoring system composed of analog instrument such as fft analyzer, amplitude analyzer and so on. the system has the shortcoming as follows : not enough friendly user interface, unitary function, under abundant analytical contents, poor generality, long developing period, high cost and so forth

    目前對滾動軸承信號識別主要採用模擬監測系統，系統均由模擬量儀器組成，如fft分析儀、幅值分析儀電平記錄儀等，系統存在操作界面不夠友好，功能單一，分析內容欠豐富、通用性差、開發周期長、成本高等缺點。
  4. When passed through the beam - splitter, a pulsed laser beam was split into 3 beams with an interpulse delay of 13 ns. these 3 separated laser pulses reach the m - z interferometer at different time and each laser pulse gave a snapshot of the implosion state. thus three different - time interferograms can be obtained in one shot of z - pinch

    激光器發出的光束經過分光系統被分成時間間隔13ns的三束光，它們于不同的時刻先後到達m - z干涉儀，每一束激光脈沖可以記錄下等離子的一個狀態，從而可以得到三幅不同時刻的干涉圖。
  5. Owning to the erasing effect, the correlation spots have not the same brightness if the holograms were exposed with the same times while recording. the correlation spot that related to the late recorded hologram is brighter than that related to the previous one. this problem can be solved by a subsequence exposure technique using in holograms receding

    本論文的研究發現，由於后記錄全息圖的寫入光束對先存全息圖的擦除效應，如果採用等時曝光法記錄幾百至上千幅全息圖，那麼相關點亮度將會變得均勻不一，后存比先存全息圖的相關點總體上要亮，而採用順序曝光法來記錄全息圖，就可以消除由擦除效應帶來的相關點亮度不均勻的問題。
