3. Field and application difference:- Spectrum: It is widely used to describe phenomena and concepts in optics, physics, chemistry, spectroscopy, and electromagnetic waves.- Spectra: It is commonly used to describe multiple different types or sources of spectra in the same scene or ex...
An investigation is made on the spectrum and fine spectrum of the generalized difference operator Δab on the space cs of convergent series. Some related results, concerning the spectrum of the adjoint operator Δab=Δab on the space bv of bounded variation sequences, are also derived. Further...
4) Difference-spectrum 差示光谱 5) spectrum subtraction 光谱差减 1. To realize multi-component analysis of air quality detecting,an gas quantitative method combining technique of Fourier Transform Infrared (FTIR) spectroscopy and the method of spectrum subtraction was applied. 针对大气质量检测的多...
A Temperature-Emissivity Separation Method Using an Empirical Relationship between the Mean, the Maximum, and the Minimum of the Thermal Infrared Emissivity Spectrum A method for the separation of kinetic temperature and spectral emissivity on the thermal infrared multispectral remote sensing data of the...
In the study of the asymptotic behaviour of solutions of differential-difference equations the A -spectrum has been useful, where spAϕ:={ω∈R:f∈L1(R,C) and ϕ∗f|J∈A implies Fourier transform f^(ω)=0} , with A given ⊂Lloc1(J,X) , φ∈L ∞(ℝ,X), X a Banach ...
The hydrogen spectrum may be considered as evidence of a step-like process in which an electron is captured and bound increasingly strongly in the field surrounding the nucleus, the stages of this process being the stationary states of the atom. Simple arguments lead to the conclusion that the ...
Difference Between the Absorption Spectrum and Emission Spectrum These are some important differences between the absorption spectrum and emission spectrum. If the question being asked is the difference between emission spectra and absorption spectra, we should mention a minimum of three differences concludi...
The comparison of the near UV absorption spectrum of native κ-casein with that of a model compound mixture (Ac-tyr-OEt+Ac-trp-OEt, molar ratio=9:1) showed a red shift of the former by 2nm to the longer wavelength. The difference spectra produced by the addition of urea to κ-casein...
As input for the random forest model, MS2Query uses five different features, calculated between the query spectrum and each of the 2000 preselected library spectra. These features are Spec2Vec similarity score30, query precursor m/z, precursor m/z difference, a weighted average MS2Deepscore over...
The five different chitosans were analyzed by infrared spectrometry and found a little difference in their spectra. It is suggested that their basic structures be similar, yet there were a slight differences in conformation and crystallinity. 展开 ...
