摘要	The mechanism driving the episode of large mass loss called superwind from an AGE star with initial mass of 7 M(circle dot) is studied by comparing the current luminosity of the star with its maximum luminosity set by the balance of several inward and outward acceleration mechanisms (gravity, radiation, rotation, and turbulent forces). The current luminosity during the AGE phase can exceed the maximum luminosity causing mass ejection from the AGE star. The periodic variation of the luminosity is in turn caused by variations in the energy output from the H-burning shelf, which are not related to the thermal pulses of the He-burning shell. The nature of the oscillatory behaviour of the H-burning shell is briefly investigated.
