3 Terms and Definitions
GB/T 13966, GB/T 14666 and established in the following terms and definitions apply to this section.
3.1
Use the sample atoms (or ions) emitted characteristic line spectrum wavelength or intensity to detect the presence of elements and their content method.
3.2
Atoms or ions by electron transition between energy levels, emit certain wavelengths of light, generated by a series of fine lines composed of spectrum.
3.3
By a number of light and dark areas separated by band spectra produced after the gas molecules are excited.
3.4
Hot solid or liquid emitted in the entire region of the spectrum spectral lines no boundaries.
3.5 Atoms in the outer electronic transition lines generated
In front of wavelengths marked with the symbol "I" indicates that this line is an atomic line.
3.6
Atoms are excited by the loss of one or several electrons radiated spectrum. Atoms are ionized, becoming lost an electron ionization time, losing
Two electrons twice called ionization. Ions generated corresponding line is called a line ionization, ionization line twice. Wave
Long front with the symbol "II" indicates once ionization line, with the symbol "III" represents twice ionization line.
