Such spectra are characteristic of chemical elements and the presence of any particular element is revealed if the emission spectrum contains the lines characteristic of that element. The line-absorption spectrum of the elements is such that only those wavelengths which can appear in the emission ...
Twitter Google Share on Facebook line spectrum Thesaurus Medical Encyclopedia Wikipedia Related to line spectrum:continuous spectrum n. A spectrum produced by a luminous gas or vapor and appearing as distinct lines characteristic of the various elements constituting the gas. ...
I propose that these excess intensities may be explained by characteristic X-ray emission by the atoms of elements present in the interstellar and/or intergalactic regions, where these lines may be excited by the interaction of charged cosmic ray particles with those atoms. I suggest that if ...
3.1.2.2 Adaptive Line Spectra Enhancer The principal block diagram of an adaptive line-spectra enhancer (ALE) is given in Fig. 3.7. The original signals consist of broadband noise and single-frequency signal Acos(2πf0t+φ). Because the single-frequency signal has a period of 2π, any del...
It was found that by a certain frequency components of spectral characteristics, they are a discrete spectral line, is called a Line spectrum, i.e. , atomic spectra. 翻译结果5复制译文编辑译文朗读译文返回顶部 The people discovered by certain frequency component constitution characteristic spectrum, th...
Plural spectra (spĕk′trə) or spectrums 1. An arrangement of electromagnetic radiation by frequency and wavelength. As a whole, the electromagnetic spectrum ranges from radio waves to gamma rays. The visible spectrum is a band of colors seen when white light is broken up according to wa...
This kind of spectra is characteristic for 2,4,6-trinitrocyclohexadienyl anion system where two absorption maxima generally appear in between 400 to 600 nm depending on the substituents attached to the spiro carbon41. Because of the presence But the system ohfastharneeelheicgthrloynerleiccht...
The Use of Artificial Neural Networks for Automatic Analysis and Genetic Identification of Gliadin Electrophoretic Spectra in Durum Wheat Each wheat cultivar has a characteristic spectrum of gliadins. This makes it possible to use blocks of the components of reserve proteins as genetic marker... VV ...
The characteristic features of the Auger resonant Raman effect are derived analytically. The theory is applied to the analysis of high resolution resonant Auger spectra recently measured at the VUV beam line at Elettra, Sincrotrone Trieste.doi:10.1080/002689797170149...
of the estimated azimuth variance and corresponding power of the line spectrum band depends on the line spectra ratio(LSR)of the line spectrum.The change laws of the output signal to noise ratio(SNR)with the LSR,the input SNR,the integration time and the filtering bandwidth of different ...
