It begins when a feeling of stillness creeps into my conciousness . everything has suddenly gone quiet . birds do not chirp . leaves do not rustle . insects do not sing 起初，有一种平静的感觉悄然爬上我的心头。世间万物，顿时沉寂。鸟儿不再啁啾，树叶不再婆挲，昆虫不再吟唱。
Under the condition that the beam is chirped , demands for soliton formation from gauss beam and the evolution equations of the beam chirp in the propagation are obtained 我们得到了在光束具有线性空间啁啾的条件下高斯光束形成孤子的条件以及传输过程中光束啁啾的演化方程。
In the distance , the constant echo of monkeys chattering and birds chirping was occasionally punctuated by strange sounds as if the animals in the jungle were attending night school 远方持续传来猴子的叽喳叫声与啁啾鸟鸣，偶尔还插进一些奇怪的声响，彷佛丛林中的动物正在上夜校一般。
We study the propagation of ultrashort chirped pulse beams in free space . the results show that the chirp influenced on the spatial singularity more than the width of the pulse beam 但是对于啁啾脉冲光束，啁啾导致的脉冲光谱展宽仍然会导致脉冲光束的空间奇异性，脉冲啁啾比脉冲长度对脉冲空间奇异性出现的影响更大。

3 . we designed and realized a high - speed sensor multiplexing network system based on the chirp fiber grating and edge filter technique . the high - speed wavelength demodulation of fiber bragg grating sensor has been turned into practice 3 .提出并设计完成了基于啁啾光栅的高速传感复用网络系统,结合边沿滤波技术,实现了传感光纤光栅的高速波长解调。
The results show that linear spatial chirp upsets the balance between diffraction and nonlinearity , leading to radiation and thus destroying the condition for the formation of soliton , although it doesn ’ t affect the central 结果表明:线性空间啁啾虽然对光束传输的中心位置没有任何影响,但它打破了衍射与非线性效应的平衡,导致光束发散,从而破坏了孤子形成的条件。
