摘　　要：将光脉冲在克尔介质中自作用产生的折射率变化作二阶近似，求解所得到的传播方程，得到啁啾高斯脉冲幅度，脉冲宽度和周啾参数随传播距离变化的严格解析解，讨论了基模高斯脉冲孤波传播的条件。Based on two order approximation of the variation of refraction index produced by self action while optical pulses are traveling in Kerr medium,the propagation equation has been solved.Furthermore,the strict analytical expressions of the amplitude,width and chirp parameter of chirped Gaussian pulse,relative to the propagation distance,are deduced.The solitary wave traveling conditions of fundamental mode Gaussian pulse have been discussed.
