摘要：

The evolution of a binary system consisting of a 8M. and 5.5M. star has been studied in the conservative approximation of Case B mass transfer. Specific attention is given to the effect of exchange between the orbital angular momentum and the spin angular momentum as the primary component evolves to a red giant and in the phase of mass transfer. It has been found that the system considering the spin angular momentum will evolve to a longer orbital period and with a smaller endmass of the primary. It shows that the spin angular momentum cannot be neglected in the calculating of the evolution of binary systems.
