摘　　要：文章得出在零色散波长处二阶色散（β２）为零时，光信号在弱非线性与三阶色散（β３）的共同作用下的频域级数解，得出了高斯脉冲在光纤中传输时的近似频域表达式，并利用数值积分方法计算出时域波形与脉冲展宽因子演化图。The series solution in frequency domain under the common influence of optical signal in weak nonlinearity and third-order dispersion β 3 has been got when second-order dispersion β 2 is zero. The approximate formula of Gaussian pulse in frequency domain has been obtained when Gaussian pulse is transmitted in fiber. Using numeric integral calculation method, the figures of waveform and pulse broadening factor are given.
