peaks
The liquid chromatograms obtained by TIC from ESI-MS provided more information on chromatographic peaks than those obtained by DAD or TIC from APCI-MS.
      
The maximum RRS peaks are at 307 nm (hsDNA, sDNA) and 290 nm (ctDNA), and other peaks are at 350 nm.
      
The main characteristic peaks in these transient absorption spectra were attributed and the growth-decay trends of several transient species were investigated.
      
Three oxidation peaks were observed for CO absorbed on Pt-CNTs/GC electrodes.
      
Among the three oxidation peaks, peak I was presumed to be due to the bridged CO absorption while peaks II and III were attributed to the split in the linear CO which is absorbed on the Pt-CNTs/GC nanocluster with different particle size and Pt film.
      
On clear days during the growing season, the sap flow density exhibited mono-peak diurnal patterns, mostly between 10:00 and 14:00, except for Phellodendron amurense, whose sap flow showed two peaks during the daytime three times.
      
In the same manner, some volatile compounds in the AD leaves treatment displayed their peaks just after 1 h, but others after 24 h.
      
The AD and ID leaves at the damage level of 25%-40% did not exhibit an obvious regularity with time; however, in 60%-75% AD leaves, peaks of volatile substances were attained after 1 or 2 h.
      
At the beginning of wear, the hard peaks from the friction surface of the disc-brake plough on the surface of the brake block.
      
A grating with two equal transmission peaks of 19.5 dB is obtained by using this method, and the separation of the two Bragg wavelengths is 0.78 nm.
      
There are other observations, such as the non-linear Fowler-Nordheim plot and multi-peaks field emission energy distribution spectra, indicating that the field enhancement is not the only story in the FE of CNTs.
      
The effect of intensity-enhancing in the PL peaks cannot be explained within the quantum confinement alone.
      
It peaks at 16-24 weeks' gestation and decreases gradually afterwards.
      
CK19 expression peaks during the 6th-11th weeks in hepatic cord cells and decreases gradually afterwards, except for the ductal plates.
      
By increasing the annealing temperature to 800°C, it is found that all the ZnO peaks have the strongest intensities, and the crystallinity of ZnO is more consistent on the SiC buffer layer.
      
The PL peaks shift with an increase in the annealing temperature, which is due to the ZnO and SiC layers penetrating reciprocally.
      
The experimental results indicate that the emitted PM has a bimodal distribution having two peaks around 4.0 μm and 0.1 μm.
      
Two peaks of chitinolytic activity were observed during cultivation of strains B-10 (350 and 450 pU/cell) and M-1 (2200 and 2400 pU/cell).
      
The enzymes were active within a broad range of pH values, with two peaks of activity being located in the acid and alkaline pH areas; required calcium ions; and exhibited substrate specificity with respect to azogelatin.
      
Proposed was a method of smoothing the spectrum of vocal signal which is based on the histogram analysis of the peaks of the spectral envelope and represents a variety of the frequency analysis that is synchronous with the main tone.
