建立了固定安全时距和可变安全时距模型，进行了线性稳定性分析及启动、跟驰和急停三种情形下的仿真。(The fixed safety time distance and variable safety time distance model are established, and the simulation of linear stability analysis and three cases of starting, following and stopping are carried ou

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
