Sentence examples for mode and negative from inspiring English sources
The mode of working process is composed of positive pressure mode and negative pressure mode.
The method was based on selective liquid/solid extraction, combined with liquid chromatography electrospray ionization tandem mass spectrometry in the multiple reaction monitoring mode and negative ionization.
In MSE centroid section: (1) acquisition: acquisition times, from start time 0 min to end time 40 min; source: ES; acquisition mode, positive or negative polarity, that means each sample was analyzed in positive ion mode and negative ion mode through different sample injections; analyser mode, resolution; dynamic range, extended.
Variational mode decomposition (VMD) is utilized for the merits which are entirely non-recursive, free from pseudo mode and negative frequency and much robust to noise to decompose a signal into a set of mono-components, based on which the instantaneous amplitude energy is calculated.
