spectral signature

基本解释

The concepts of total luminescence spectroscopy (TLS) and spectral fluorescent signature (SFS) technique are introduced.
介紹了縂熒光光譜（TLS）和特征光譜熒光標記（SFS）技術；
So we know the spectral signature they would see, and the changes, " said Haqq-Misra, whose primary research involves studying the atmospheric changes caused by life."
因此我們知道，他們會看到地球的光譜特征j及其變化”，主要從事研究人類生活造成大氣變化的哈尅-米斯拉說。
X-ray emissions observed over 5 days allowed the researchers to see through to the center of five of the blobs. The spectral signature of each one revealed a supermassive black hole.
射線的釋放，使他們看明白了其中五個氣泡的中心——每個氣泡中心的光譜信號都顯示出一個超大質量的黑洞。
