基本解釋

Moreover, there were certain differences in second derivative near-infrared spectra of the two samples.

The spectra were analyzed to calculate relative intensity ratio, bandwidth, as well as the second derivative spectra and Multi-peak Gauss fit of fluorescence spectrum.
本文計(jì)算了熒光的相對(duì)強(qiáng)度比、半值寬度，對(duì)熒光光譜做了二階導(dǎo)數(shù)，以及譜圖分離等處理，對(duì)熒光光譜數(shù)據(jù)作了深入細(xì)致的分析。
