In order to reduce time consuming of computation, some accelerated techniques were studied such as parallel, implicit method of DP-LUR and dual time stepped method.
为了减少计算时间,研究了并行、隐式DP - LUR方法、双时间步长法等计算加速技术。

General speaking, the matrix inversion will consume a large amount of computation time, which heavily hinder the application of 3-d implicit scheme in waveform migration.
