| 英文摘要 | Stokes polarization profiles of the Mg b(2) 5172.68 angstrom spectral line on two simple sunspots are obtained with the Multi-Channel Solar Telescope (MCST) at the Huairou Solar Observing Station (HSOS). This is done by means of scanning this line over the wavelength interval from 200 m angstrom redward of the line center to 200 m angstrom blueward, in steps of 10 m angstrom. A generalized analytic solution to the transfer equation for polarized radiation is presented. With a nonlinear least-square fitting technique, the linear calibration coefficients for the low-chromospheric longitudinal magnetic field is obtained in the weak-field case. We also discuss the problems in calibrating the transverse field with this line. It is shown that the weak-field approximation is not applicable to the chromospheric Mg b(2) line for the transverse component of the magnetic field. |
