啁啾发出连续的轻的啁啾声或抖动的声音；发连续的吱喳声

When the chirped pulse with area smaller than propagates in the medium, splitting doesn't occur and the chirped pulse evolves gradually to an approximate normal Gaussian pulse (C=0), and this characteristic doesn't vary when the chirp coefficient; however, variation of the chirp coefficient will change amplitude and group velocity of the pulse.

面积小于的啁啾脉冲，在介质中传播时不发生分裂，且啁啾脉冲逐渐演化为一个近似的无啁啾(C=0)脉冲，这一特点不随啁啾系数的改变而改变；但啁啾系数的变化将改变脉冲的振幅和群速度。

It′s found that the GVD-caused chirp in the exponential type of DDF is least likely to be affected by the initial chirp,the GVD-caused chirp in exponential, linear,Logarithm and Guassian types of DDF has the synchronous character of saturation as the nonlinear-effect-caused chirp ,and the two kinds of chirp are found to counteract to balance, which makes the sum chirp tend to be zero.

发现指数型色散缓变光纤中初始啁啾对GVD所致啁啾的影响最小，在指数型、线型、对数型和高斯型色散缓变光纤中GVD所致啁啾具有同非线性效应所致啁啾相似的饱和性，二者相消，使净啁啾趋于零。

However, the pulse width becomes broad considering TOD or FOD.

而当考虑到三阶色散、四阶色散时，初始啁啾导致脉冲宽度大于无初始啁啾脉冲的宽度。

Based on the Rayleigh-Sommerfeld diffraction integral and complex analytical signal representation,the free-space propagation equation and its Fourier spectrum for ultrashort chirped pulsed Gaussian beams are derived,and the far-field analytical electric field and spatial intensity are presented.

基于瑞利-索末菲衍射积分，使用复解析信号法推导出了啁啾脉冲高斯光束在自由空间中的传输方程及其傅里叶谱，给出了远场的光场和空间光强的解析式，研究了啁啾参数C对脉冲光束传输的影响。

The result shows that, in the case of low power, it is important for the chirp to form the soliton and transmit in the abnormal and zero dispersion area, but it's bad for the pulse's transmission in normal dispersion.

结果表明，较低功率时，反常色散区和零色散区，初始啁啾对于孤子的快速形成和传输具有重要的作用，而位于正常色散区时，啁啾破坏了脉冲形状，不利于脉冲的传输。

It's good for chirp to broad spectrum in normal and abnormal dispersion area, but not evidence in zero dispersion.

反常色散区和正常色散区啁啾有利于频谱的展宽；零色散区，啁啾对频谱展宽影响不明显。

We compare the effect of eliminating the chirp by means of linearly chirp fiber Bragg grating, normal dispersion fiber and F-P cavity.

因此我们认为光纤光栅消啁啾是消除脉冲中心部分的啁啾，脉冲前后沿啁啾消除情况，决定于啁啾的类型。

我只能听到远处一只小黄鸟在啁啾啁啾地歌唱，还有一只蝉在发出催眠的叫声，不然就真是万籁俱寂了。

Chirp：啁啾

在有线电视系统HFC(光纤同轴混合结构)中,直接调制型DFB激光器的光发射机,由于直接调制激光器时,在光强度变化的同时,波长也发生了变化,即产生了附加频率调制,这种现象也叫"啁啾"(Chirp),这样会使调制边带进一步展宽.
