Scientific paper

Abundances of 15 elements are determined in two superficially normal stars 21 Peg (B9.5 V) and HR 7338 (A0 III) with model atmosphere techniques. Adopted atmospheric parameters (Teff, log g, ξ1) are (10,500, 3.5, 1.0) and (9500, 3.0, 0.5) for 21 Peg and HR 7338, respectively. Abundances of metals are nearly solar or slightly underabundant in 21 Peg except for Mn, Y, and Ba, which may be overabundant. Nearly all the metals are underabundant in HR 7338. Among others Al, Si, Sc, Ti, and Fe are underabundant by more than a factor of 5 in HR 7338.
