摘要	The high resolution, high S/N spectra for the chromospherically active binary AR Psc (=HD 8357) has been obtained by using the Coude echelle spectrograph of the 2.16 m telescope of Beijing Astronomical Observatory. The H-alpha lines present emission above the continuum and the profiles of CaII IRT2 ( lambda 854.2 nm) & IRT3 ( lambda 866.2 nm) show core emission. The net chromospheric flux of the had been calculated by using spectral subtraction. A detailed spectroscopic analysis and model calculation have yielded the atmospheric parameters of the primary of AR Psc. The abundances of 9 elements has been obtained. And, the measurement of Magnetic field have been made using the Stenflo-Lindegren statistical analysis and the profile-addition technique. A magnetic field strength B = 2400 +/- 300 G and filling factor alpha = 0.45 +/- 0.05 are obtained. (c) 2005 Elsevier B.V. All rights reserved.
