background determination

基本解释

In the work, novel and fast approaches for identifying single molecules and the determination of signal to background ratio were presented based on single event photon statistics.
研究利用單事件光子統計直接測量單分子光子源的信號背景比和快速判斷單分子。
We theoretically discussed the synchronization sample gate time determination by considering the optimal Signal-to-Noise Ratio (SNR) where the background showed time-uniformity distribution.
本文通過最佳信號噪聲比分析，討論了單分子輻射單光子在具有時間均勻分佈背景信號時對同步取樣時間的選取。
Objective:To develop a method for determination of lead in salt by GFAAS using organic reagent as matrix modifier, which could eliminate the background Absorb and matrix interference produced by NaCl.
目的：用有機試劑爲基躰改進劑來消除GFAAS測定食鹽中鉛的背景吸收和基躰乾擾，建立有機基躰改進劑GFAAS測定食鹽中鉛的方法。
