啁啾發(fā)出連續(xù)的輕的啁啾聲或抖動的聲音；發(fā)連續(xù)的吱喳聲

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.

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.

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

而當考慮到三階色散手机免费黄色网站电影免费在线观看、四階色散時亂倫图片网，初始啁啾導致脈沖寬度大于無初始啁啾脈沖的寬度。

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-索末菲衍射積分大家操网，使用復解析信號法推導出了啁啾脈沖高斯光束在自由空間中的傳輸方程及其傅里葉譜欧美性爱xxⅩx，給出了遠場的光場和空間光強的解析式，研究了啁啾參數(shù)C對脈沖光束傳輸?shù)挠绊憽?/p>

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.

結果表明XXXX.WWW.com69，較低功率時人人操人人看人人玩，反常色散區(qū)和零色散區(qū)，初始啁啾對于孤子的快速形成和傳輸具有重要的作用欧美一级视频免费观看，而位于正常色散區(qū)時性按摩一级毛片，啁啾破壞了脈沖形狀，不利于脈沖的傳輸高清无码亚洲黄网。

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