摘　　要：主要讨论建立大质量双星非守恒演化理论中的一些重要问题。The problems for the development of non - conservative evolution of massive binary systems are discussed. These are: the effects of tide, rotation and irradiation on the rate of mass loss due to stellar winds, the relation between the mass loss and the angular momentum loss, the calculation of the obital separation between the two components under nonconservation of mass and angular momentum, the effect of radiation on the Roche lobe and the mass - transfer, the occurrence of spiral - in process and the change in the orbital separation after loss of the envelope, the condition for non - disruption of the binary system under supernovaexplosion, the dynamics for the shock fronts of stel1ar winds and .the effect of shock fronts on the evolution of massive binary systems.
