The phrase "area of spectral" is not complete and lacks context, making it difficult to determine its correctness in written English.
It could be used in contexts related to physics, music, or analysis where "spectral" refers to a spectrum or range of frequencies, but it needs additional words to clarify its meaning.
Example: "The area of spectral analysis is crucial for understanding the properties of sound waves."
Alternatives: "field of spectral" or "domain of spectral".
The energy (area of power spectral density function) and the intensity (magnitude of power spectral density function) are fixed and the critical excitation is found under these restrictions.
The area of each spectral region was divided by the sum of all spectral areas in order to obtain a relative percentage.
In Fig. 4, all wavelet coherence analyses show an area of high spectral power in the middle of the time range.
The power (area of power spectral density, PSD, function) and the intensity (magnitude of PSD function) are fixed and the critical excitation is found under these restrictions.
In the Mössbauer spectra of glasses from Kara and Ries craters (Fig. 7), the most intense doublet D1 with nearly equally large widths (0.5 0.6 mm/s) and the contribution to the total area of the spectral contour is characterized by IS, characteristic of 6-fold oxygen polyhedra with Fe2+, that is, the octahedral type of sites in the aluminosilicate glass46,47,48,49.
While deviations in the focal plane temperature can also influence the effective area of grating spectral analyses through the order sorting performed by the tool tg_resolve_events, analyses of imaging and timing data are insensitive to deviations in the focal plane temperature.
The water region was excluded (4 6 ppm), and data were normalized to the total area of the spectral integral.
Furthermore, in MRS the area of the spectral peak is proportional to the concentration of the corresponding metabolite (absolute concentrations require calibration).
Pearson correlation analysis was carried out among basal area, volume, values of spectral bands, and vegetation indices.
The areas of the spectral contours of D3, D4 doublets are approximately equal (Fig. 7C).
