摘要：

We have measured the abundances of Fe, Si, Ni, Ti, and Na in 20 Pleiades stars with T(eff) values near solar and with low v sin i using high-resolution, high signal-to-noise echelle spectra. We have validated our procedures by also analyzing 10 field stars of a range of temperatures and metallicities that were observed by Valenti and Fischer. Our result for the Pleiades is [Fe/H] = + 0.03 +/- 0.02 +/- 0.05 (statistical and systematic). The average of published measurements for the Pleiades is + 0.042 +/- 0.021.
