spectral background

基本解釋

The spectral background was lower. Sensibility of the analysis of Au is increased.
結(jié)果表明，用腈綸網(wǎng)做樣品底托，光譜背景底，分析靈敏度高。
First, a cuvette filled with distilled water must be scanned as a blank to provide a spectral background.
首先，要掃瞄一個(gè)裝有蒸餾水的比色皿作為空白，以提供一個(gè)光譜背景。
The algorithm simultaneously achieves quantitation of the vapor spectral transmission, background removal, real time calibration for FTIR .
該算法在完成定量分析蒸氣透過(guò)率的同時(shí)，還進(jìn)行了目標(biāo)背景的實(shí)時(shí)扣除和對(duì)FTIR儀器的實(shí)時(shí)定標(biāo)。
