CCD spectra of the solar-like star ∊ Eri with high-resolution, high signal-to-noise ratio were obtained using the coudé spectrograph of Yunnan Observatory from Feb. 1993 to Nov. 1994. Preliminary results of the determined magnetic field of ∊ Eri are presented. The authors used two methods which are the profile-addition-technique of spectral profiles of Zeeman broadening and the Stenflo-Lindegren statistical analysis. A brief description and discussion for two methods were made.
