  1. According to these accomplishments, several techniques are expounded emphatically in this paper, including 3d refraction statics, coherent noise suppression by prestack wave field separating ( prestack fx noise attenuation ), 3d prestack multiple domain random noise attenuation, multiples attenuation, nmo of unsymmetrical hyperbola, dynamic replacement of wave equation, surface - inconsistent residual static, super bin stacking, poststack depth migration and prestack depth migration. all the techniques have been applied in seismic processing of 2d, 3d and wide - line profiling and obtained good results

    本文根據項目組研究成果，重點閘述了三維折射波靜校正技術，疊前波場分離相干噪音壓制方法（疊前fx去噪） ，疊前三維多域隨機噪音衰減技術，多次波衰減技術，非對稱雙曲線動校正技術，波動方程動態替換技術，非地表一致性的剩餘時差靜校正技術，超面元迭加處理技術，疊后深度偏移處理，疊前深度偏移處理等。
  2. Based on the simple understanding of normal seismic processing, this paper has carried out deep research on the problems of deep prospecting in seismic data processing, such as s / n ( signal to noise ratio ), velocity analysis and residual nmo of unsymmetrical hyperbola, stacking and imaging of complex rays and migration arc. until now tens of accomplishments have been achieved

    在簡單了解地震資料常規處理的基礎上，本文針對當前深層資料的問題，緊緊圍繞著深層地震數據處理技術研究需要解決的重點問題，即信噪比問題、非對稱雙曲線的速度分析與剩餘動校正時差問題、復雜射線的迭加及偏移成像問題和偏移畫弧問題等，進行了深入的研究工作，目前已完成十多個成果。
  3. The level set methods proposed by s. osher have a good property of geometry interpolation, and gray interpolation can be changed into curve interpolation. actually, it has great influence on image processing and have achieved satisfactory results in image restoration, noise - removing, edge detection, image matching, and image recognition

    由s . osher等提出的水平集方法具有良好的幾何插值性，將灰度插值轉化為曲線插值，在圖像處理中有很大的影響，在圖像修復與去噪、邊緣檢測、圖像匹配、圖像識別等方面都取得了相對較好的結果。
