forward-difference method

常见例句

Good results also verify the feasibility of forward modeling with two-dimensional finite difference time domain method (2D-FDTD).
良好的结果也验证了二维时域有限差分法（2D-FDTD）正演模拟的可行性。
In the forward step, the eikonal equation was solved by finite-difference method. Raypaths were determined in the minus gradient direction of travel time.
正演采用快速的有限差分求解程函方程的方法求取旅行时，利用旅行时的负梯度方向求取射线路径。
