英文摘要	A set of two-dimensional Stokes spectral data of NOAA AR 10197 obtained by the Solar Stokes Spectral Telescope ((ST)-T-3) at the Yunnan Observatory are qualitatively analyzed. The three components of the vector magnetic field, the strength H, inclination gamma and azimuth chi, are derived. Based on the three components, we contour the distributions of the longitudinal magnetic field and transverse magnetic field. The active region (AR) has two different magnetic polarities apparent in the longitudinal magnetic map due to projection effect. There is a basic agreement on the longitudinal magnetic fields between the (ST)-T-3 and SOHO/MDI magnetograms, with a correlation coefficient rho(Bl) = 0.911. The transverse magnetic field of the AR has a radial distribution from a center located in the southwest of the AR. It is also found that the transverse magnetic fields obtained by Huairou Solar Observing Station (HRSOS) have a similar radial distribution. The distributions of transverse magnetic field obtained by (ST)-T-3 and HRSOS have correlation coefficients, rho(Azimu) = 0.86 and rho(Bt) = 0.883, in regard to the azimuthal angle and intensity.
