In the article, the fully discrete finite difference scheme for a special nonlinear reaction-diffusion equation is established. 對(duì)一類特殊的非線性反應(yīng)擴(kuò)散方程進(jìn)行完全離散，得到非線性的有限差分格式。
A novel numerical algorithm SSFD (split-step finite difference) has been presented for solving nonlinear pulse propagation equation. 提出了一種新型的分步有限差分（SSFD）算法來(lái)求解非線性鎖模脈沖傳輸方程。
