顶盖驱动流是不可压缩黏性的典型流动，可以用来检验各种数值算法计算精度和可靠性，目前尚不能求得它的解析解。基于Fortran 编程，采用 SIMPLE 算法求解二维方腔流动，得到流动达到稳定状态时各物理量的分布。(Lid-driven cavity flow is an incompressible viscous flow, which can be used to test the accuracy and reliability of various numerical algorithms

超短脉冲是谐振腔中增益与损耗达到平衡、色散与非线性达到平衡时所产生的。啁啾型脉冲在光纤中传播，因色散作用及各种非线性作用谱线被展宽。(Ultra-short pulses are generated when the gain and loss of the cavity are balanced, and the dispersion and nonlinearity are balanced. Chirped pulses propagate in optical fibers, and t
