  1. For processing of 3d and 3c seismic data, the reflected p - waves can be processed with the conventional methods, while the reflected converted waves can not be processed with the conventional p - wave processing methods, because their travel paths are asymmetrical, their common midpoint gathers are no longer common reflection point gathers, and their time - distance equation is non hyperbolic

    在三維三分量地震勘探資料處理中，對于反射縱波資料可以採用常規方法進行處理；而對于反射轉換波資料，由於其傳播路徑的非對稱性，轉換波共中心道集不再是共反射點道集，轉換波時距方程也不是雙曲方程，因此不能採用常規縱波處理方法來處理轉換波資料。
  2. Alarms can go out before the shaking starts because there is a lag between the time it takes for different seismic waves to travel to the surface

    預警能夠在地震開始前發出是由於在不同的震波到達地面之間會有一個時間差
  3. This paper presents the prestack time migration to curved rays for minor fault blocks, which is of more accurate migration, allowing the travel - time equation to be more close to the real pathway of layered media seismic wave propagation, the focused imaging to be more precise, the migrated results to be of good preserved amplitude processing property and the output trace gathers to be used for the lithologic analysis and inversion study

    採用彎曲射線疊前時間偏移技術使小斷塊準確偏移歸位，其走時方程更接近層狀介質地震波的真實傳播路徑，成像聚焦更精確，且通過特殊振幅處理，其偏移結果有很好的保幅性，輸出的道集可以用於巖性分析和反演研究。
