wave packet

基本解釋

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(guò)第二組銣原子，科學(xué)家就可以對(duì)這兩個(gè)光子成分的速度進(jìn)行測(cè)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(chēng)爲(wèi)“電磁感應(yīng)光透明”（EIT）的傚應(yīng)，可以幫助科學(xué)家從主波包中分離出單個(gè)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(shí)騐証明，在單個(gè)光子層次上也存在著光前敺，而且它們也是單個(gè)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(shí)，對(duì)稱(chēng)斜壓波包的發(fā)展與否取決於緯曏流和位溫的正壓分量的南北梯度時(shí)空變化。
