spectral signature

基本解释

The concepts of total luminescence spectroscopy (TLS) and spectral fluorescent signature (SFS) technique are introduced.
介绍了总荧光光谱（TLS）和特征光谱荧光标记（SFS）技术；
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."
因此我们知道，他们会看到地球的光谱特征j及其变化”，主要从事研究人类生活造成大气变化的哈克-米斯拉说。
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.
射线的释放，使他们看明白了其中五个气泡的中心——每个气泡中心的光谱信号都显示出一个超大质量的黑洞。
