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.

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.
本文通过最佳信号噪声比分析，讨论了单分子辐射单光子在具有时间均匀分布背景信号时对同步取样时间的选取。
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：用有机试剂为基体改进剂来消除GFAAS测定食盐中铅的背景吸收和基体干扰，建立有机基体改进剂GFAAS测定食盐中铅的方法。
