【 摘 要 】
A high resolution spectrum of a pre-main sequence star HD 377 is analyzed. The atmospheric parameters are found to be: Teff =5875 K, log g = 4.25 and the microturbulent velocity ξt = 1.40 kms−1. The metallicity of HD377 is slightly higher than of the Sun, [Fe/H]=0.21. The lithium abundance is very high log ε(Li) = 3.02.
