摘要：

Using recently published opacity tables, the evolution and stability of a 15-M. star with initial metallicities Z = 0.02 and 0.03 is re-examined. For Z = 0.03, radial and non-radial pulsations are found to be unstable for 4.326 < log T(eff) < 4.43. Implications of the results for the beta-Cepheid phenomenon are discussed.
