摘　　要：对16颗旋转周期增加的半相接双星的质量交换速率进行了研究.运用经典的O-C周期分析方法,分析了其周期变化率和质量交换速率;讨论了影响质量交换率的因素,表明质量交换率随质量比的增大而增大,指出质量比是影响它的一个重要因素之一.In this paper, 16 semi-detached binaries of increasing orbital period were chosen to be to investigated of the mass exchange rate. As the approach of classical O-C diagram, the rate of orbital periods and the mass exchange rates were analyzed. Finally, the influence factor of the mass exchange rates was discussed. It presents that the mass exchange rate is increasing with the rising mass ratio. It means the mass ratio is a important factor.

关 键 词：半相接双星 轨道周期变化 质量交换率
