查询词典 distances

It is shown that the M×N ChG beams in turbulent undergo three stages of evolution with increasing propagation distance,and turbulence accelerates the evolution of three stages.The turbulence results in a spreading and degradation of the maximum intensity in the far field.But β-parameter decreases with increasing beam numbers M,separate distances xd and beam parameter δ.And there exists optimal values of xd and δ,and SR of the corresponding M×N ChG beams reaches its maximum.

研究表明：在湍流大气中，双曲余弦高斯列阵光束的传输将经历三个阶段的变化，并且湍流使得光束传输经历三阶段的进程加快；湍流导致双曲余弦高斯列阵光束扩展、最大峰值光强下降，但是，β参量随光束数目M、相邻子光束间距xd和光束参量δ的增加而减少，即光束扩展受湍流的影响减小；并且，存在最佳xd和δ值使得Strehl比取得极大值。

Atmospheric perspective is normally discussed in conjunction with landscape painting since its true effect is primarily seen in nature in conjunction with great distances in space.
