Abstract :
Chemical abundances of six OB stars are determined by the ASCA data. Low metal abundances are derived from a simple optically thin plasma model. Multi-temperature models also derive low metal abundances. We interpret that the plasmas are not optically thin for the resonance lines and the line intensities are suppressed by the absorption.
