基于广义的Huygens-Fresnel原理和非Kolmogorov谱模型，推导了无线光通信系统中径向分布部分相干高斯-谢尔模型阵列光束在非Kolmogorov大气湍流中传输时瑞利区间zR和湍流距离zT的解析表达式，对瑞利区间和湍流距离随湍流参量和光束参量的变化情况进行了数值分析.结果表明：不论是相干还是非相干合成，径向分布部分相干高斯-谢尔模型阵列光束的zR和zT均随湍流广义指数α的增大非单调变...

基于广义惠更斯-菲涅尔原理，采用Rytov方法推导了径向分布高斯阵列光束在非Kolmogorov湍流大气中传输时的光强闪烁指数表达式，分析了径向半径r0、光束个数N、广义指数α及传输距离L对轴上和离轴闪烁指数的影响。结果表明：轴上和离轴闪烁指数随着α的增加均先增大后减小，值得注意的是不同的r0光束的闪烁指数达到极大值所对应的α略有不同，轴上闪烁指数随着r0的增大达到极大值所对应的α呈减小趋势，而离...
In this paper we will give a proof of Kolmogorov’s theorem on the conservation of invariant tori. This proof is close to the one given by Bennettin, Galgani, Giorgilli and Strelcyn in [2]; we follow t...
