propagation distance

常見(jiàn)例句

The spatial coherence of the beam is not relevant to its initial coherence for longer propagation distance.
長(zhǎng)距離傳輸後，光束空間相乾性與光束初始相乾長(zhǎng)度不再有關(guān)。

We numerically show that there are many extremums in dependence of the propagation distance on the period lengths of perturbation.
數(shù)值模擬發(fā)現(xiàn)，在脈沖傳輸距離與擾動(dòng)周期長(zhǎng)度的關(guān)系中存在著一種多極值結(jié)搆。
Therefore, the R of laser beams with larger R in free space will become smaller than the R of those with smaller R in free space after a certain propagation distance in turbulence.
因此，儅光束傳輸?shù)揭欢ň嚯x之後，湍流使得原來(lái)在自由空間中較大的R變小，而較小的R變大。
