Abstract: Taking account of δr≠0,through the equation of conservation of orbital angular momentum,orbital parameters equations on the mass change are re-deduced.The equations of the orbital parameters are used to calculate the evolution of the orbital parameters and amount of accreted matter to the Ba stars.The effect of the parameters on the contamination factor are dis cussed.
