无畸变传输 meaning in English

undistorted transmission

The influence of optical source chirp on femtosecond soliton interaction is studied numerically , and the unequal amplitude method can reduce the interaction . in addition high - order coupled equations governing the evolution of two orthogonal polarization components of the same wave are derived by using multi - dimension derivation expansion method of singular perturbation theory and the dispersion relation . furthermore , a class of optical solitary wave solutions , such as the bright - bright , dark - dark , bright - dark , and combined solitary waves are found under certain parametric conditions
数值研究了源啁啾飞秒孤子间相互作用，提出了抑制该作用的可能方案；用奇异摄动多重尺度导数展开法和色散关系推导了耦合高阶非线性薛定谔方程( chnlse ) ，并用行波变换法得到了一系列孤波解析解，分析了它们在光纤中传输的必要条件，也讨论了它们的稳定性，为实现飞秒光脉冲在光纤中的无畸变传输作理论上的探索。
