摘　　要：采用导引中心理论分析了色散管理孤子系统,证明了色散控制孤子(DMS)传输的稳定性,同时,给出了“呼吸”色散管理孤子的稳定传输条件·结合数值计算方法研究了DMS参量如幅度、脉宽、啁啾以及脉冲能量在色散管理周期内演化特性,该结果传输系统的稳定传输的特性,从而不但验证了导引中心“呼吸”孤子传输理论的结果,而且证明DMS在不同的平均路径色散条件下的鲁棒性·The guiding-center ＂breathing＂ soliton theory in dispersion managed soliton system is analysis and the stability of DMS transmission is proved. The condition of stability of DMS transmission also is given. Then, the characteristic of DMS parameters transmission evolving in dispersion map, which including amplitude, width, chirp and energy of pulse, are studied. With help of the numerical methods, it not only can be validated the results of guiding-center ＂breathing＂ soliton transmission theory, but also proved that robustness of DMS in changefully averaued disoersion value line.
