Sentence examples for middle frequency region from inspiring English sources
Therefore three frequency regions were determined which are low frequency region (LFR) (1 50 Hz), middle frequency region (MFR) (50 Hz – 50 KHz) and high frequency region (HFR) (50 KHz – 1 MHz) belonging to these relaxation processes.
The large semicircle in the middle frequency region is related to recombination resistance (R 2) and constant phase element (CPE2) at the TiO2/dye/electrolyte interface.
In the proposed method it is determined by using the time-frequency representation of the corresponding row and taking the middle frequency region.
The interfacial impedance related to the electron transfer from the conduction band of TiO2 to the electrolyte can be described by the semicircle of the middle frequency region in the Nyquist plot.
The spectra all reveal only one time constant, in which the higher frequency region represents the solution resistance (Rs), the middle frequency region's slope exhibits the capacity between the passive layer and the substrate, while the lower frequency region is a measure of the protective ability and the electrolyte property by means of the polarization resistance (Rp) [40].
The plots consist of a depressed semicircle in the high and middle frequency regions and a straight line in the low-frequency region.
The first three formants are encoded in the lower and middle frequency regions from 200 Hz to 3 kHz.
The Nyquist plots are composed of semicircle in the high-to-middle frequency regions and a sloping long line in the low frequency region.
The ring-structures of intermediate range order, boroxol, pentaborate, tetraborate and diborate groups, could be quantified from the spectra in the middle-frequency region.
Traditionally, the first semicircle in high-frequency region corresponds to charge transfer resistance (Rct) of the CE/electrolyte interface, while the second semicircle in the middle-frequency region represents charge transfer and recombination resistance in the TiO2/dye network [18, 19].
At potentials below 0.9 V, another semi-circle appeared in the middle to lower frequency region, which was assigned to the charge transfer resistance due to lithium-ion transfer at the surface-modified carbon electrode/electrolyte interface.
