One-dimension wavelength shift of atomic spectral lines in 0-800 nm spectral range was observed, and the relationships between temperature, humidity, pressure, and the magnitudes of wavelength shift of the atomic spectral lines were found, which were expressed as some polynomial equations in this paper. The universality of these wavelength shift equations (above mentioned polynomial equations) is primarily proved experimentally. The nonlinear relationship between the half-width of spectra lines and temperature was also found. Based on these equations, an intelligent wavelength calibration device (IWC) was designed in the author's lab. The analytical results of samples indicate that IWC is useful and effective.One-dimension wavelength shift of atomic spectral lines in 0-800 nm spectral range was observed, and the relationships between temperature, humidity, pressure, and the magnitudes of wavelength shift of the atomic spectral lines were found, which were expressed as some polynomial equations in this paper.
