摘要：
We have examined the wind momentum problem of O-type stars in the Galaxy. It is shown that the discrepancy between theoretical and empirical mass loss rates and terminal velocities can be reversed by using recently updated values of force multiplier parameters. With these new values, the momentum problem found by former investigators is reversed so that there now appears to be more than enough radiation force in order to accelerate the stellar winds of a sample of Galactic O-type stars.
