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，分析霛敏度高。
First, a cuvette filled with distilled water must be scanned as a blank to provide a spectral background.
首先，要掃瞄一個裝有蒸餾水的比色皿作爲(wèi)空白，以提供一個光譜背景。
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率的同時，還進行了目標(biāo)背景的實時釦除和對FTIR儀器的實時定標(biāo)。
