The SK~α X-ray spectra of various state sulphur-containing compounds were measured on RIGAKU 3070 X-ray Spectrometer (with double Ge crystals). Peak positions, asymmetry factors, RWHMs, LWHMs, chemical shifts and net charges on sulphur atom were obtained after data treatment. The relationships between chemical shifts and valences of sulphur, O/S (atom number ratio) of sulphur oxy-anions were analyzed by the linear regression. Good linearity was revealed and these results were discussed. Correlation coefficients and equations were also presented.

Key words: CHEMICAL SHIFT, LINEAR REGRESSION, X-RAY FLUORESCENCE SPECTROMETRY, SULFOCOMPOUND
