摘要：
The lithium abundance was calculated for five metal-poor red giant stars from Li doublet at 6707 (A) over cap by fitting the observed high-resolution spectra with synthetic spectra The lithium abundance was found to be low in all stars, log epsilon(Li) <= 1 8, confirming lithium depletion on the red grant and asymptotic giant branch
