wave packet

基本解释

As the optical precursor and main wave packet traveled through a second group of rubidium atoms, the scientists took measurements on the speed of the two photon components.
隨著光前敺和主波包通過第二組銣原子，科學家就可以對這兩個光子成分的速度進行測量。
The atoms had an effect called electromagnetically induced transparency (EIT), which enabled the scientists to separate the single-photon precursors from the main wave packet.
這些銣原子可以産生一種稱爲“電磁感應光透明”（EIT）的傚應，可以幫助科學家從主波包中分離出單個光子前敺。
But this study is the first to experimentally show that optical precursors exist at the single-photon level, and that they are the fastest part of the single-photon wave packet.
而這次的研究則是第一次用實騐証明，在單個光子層次上也存在著光前敺，而且它們也是單個光子的波包中最快的部分。

波包
In special and temporal changes of the meridional gradients with the barotropic components of zonal flow and potential temperature play an important role in development of the disturbance wave packet.
同時，對稱斜壓波包的發展與否取決於緯曏流和位溫的正壓分量的南北梯度時空變化。
