Evolution of Gauss Beam in Biased Centrosymmetric Photorefractive Media[J]. 引用该论文 Ji Xuanmang;Wang Jinlai;Liu Jinsong.
The character of FSK spectrum is centrosymmetric, spectrum peaks spread with an interval of the modulation frequency, so the right frequency cannot be got by FFT spectrum. 移频信号的频谱特性是谱峰以新出现的边频频率为中心，以低频频率为间隔向两边展开，通过FFT谱分析不能得到精确的结果；
Abstract: Neglecting the diffusion effect, the temperature dependence of the low-amplitude spatial soliton in the Centrosymmetric photorefractive crystal was discussed. 摘要： 在忽略扩散效应的条件下，讨论了中心对称光折变材料中低振幅空间孤子的温度特性。
Andrew's centrosymmetric matrix in [1], Chen's reflexive matrix in [9] and Trench's R -symmetric matrix in [10], then many results in this thesis include corresponding results in the above mentioned cites. Andrew讨论的中心对称矩阵、文[9]中Chen定义的自反矩阵以及文[10]中Trench引入的R -对称矩阵的推广;因而本文所得结果涵盖了上述文献中的相应结果.
Electric field applied to silicon, which is a kind of centrosymmetric materials, induces effective even-order nonlinear susceptibilities for silicon due to the vanishing of its inversion symmetry. 具有反演对称中心的硅单晶在电场作用下体内的反演对称中心消失,因而理论上应产生偶数阶非线性极化率。
