给出了色散阶变光纤中群速度色散效应导致的啁啾表达式，采用数值方法模拟了该光纤中的啁啾演变过程。研究结果表明：色散阶变光纤中的啁啾以色散缓变光纤中啁啾为中心跳跃式变化，逐渐与色散缓变光纤中啁啾重合，且比常规光纤中的啁啾小。
The chirp expression caused by the group velocity dispersion in the chromatic dispersion fiber is given. The chirp evolution in the fiber is numerically simulated. The results show that chirp in chromatic dispersion fiber changes slowly with the chirp in the chirped fiber, and gradually coincides with the chirp in the chirped fiber, which is smaller than that in the conventional fiber.
