  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. With multi - ccd and multi - computer system, video and sampling synchronization technique in lan adopted, real - time measurement of large - scale flow field was achieved. velocity distribution of the flow field with an area larger than 1000 m2 can be measured in 20 seconds

    採用多ccd攝像機和多臺計算機、視頻信號同步、局域網同步等技術,首次實現了大范圍流場的實時測量,在20秒鐘之內測量1000m2以上的流速場。
