  1. The authors established an initial velocity model based on the first break time of the actual data, then realized the forward calculation with the improved shortest path ray tracing algorithm, and applied the improved constrained damped simultaneous iterative reconstruction technique ( cdsirt ) to solve large - scale and sparse equations for inversing the near - surface velocity field

    根據實際地震數據的初至波時間建立初始速度模型；採用改進的最短路徑射線追蹤演算法進行正演；利用改進的約束帶阻尼聯合迭代重建技術（ cdsirt ）求解大型、稀疏的方程組來反演近地表的速度場。
  2. Geological model is set up by using seismic data interpretation result to perform ray - trace forward modeling analysis, and to guide the establishment of initial velocity model of pre - stack depth migration, thus reaching the purpose of precise image of complex structure under complex surface

    利用已有地震資料解釋成果，建立地質模型進行射線追蹤正演模擬分析，從而指導疊前深度偏移初始速度模型的建立，達到了復雜地表下復雜構造精確成像的目的。
  3. 2 ) forward modeling method of refraction first - break in lateral varying velocity media. for layered media, a new forward modeling method of refraction is presented. for more complex near - surface conditions such as mountain areas, a new improved ray tracing method based on shortest path assumption is studied, it has higher accuracy and faster computing efficiency than conventional ones. the method can be used for the forward modeling of complex near - surface media

    而對于折射面起伏較大、低速層和折射層速度變化較大的復雜近地表情況，提出了一種改進的最短路徑初至波射線追蹤方法，該方法精度高，計算速度快，適用於任意二維復雜近地表介質（如山地）的初至折射波的正演計算。
