数值计算了半分离二元系统内拉格朗日点附近的传质流动细节。使用多方状态方程，其中n = 3/2。计算了质量转移速率与星星填充Roche瓣程度的关系，发现与以前的解析估计很好地吻合，计算了双星系统在小偏心率时质量转移速率的变化，并以此对Papaloizou和Pringle（1979）提出的矮新星超峰模型提出了质疑。
The details of the mass transfer flow near the inner Lagrangian point in a semidetached binary system are numerically calculated. A polytropic equation of state with n = 3/2 is used. The dependence of the mass transfer rate on the degree to which the star overfills its Roche lobe is calculated, and good agreement with previous analytic estimates is found. The variation of mass transfer rate which occurs if the binary system has a small eccentricity is calculated and is used to cast doubt on the model for superhumps in dwarf novae proposed by Papaloizou and Pringle (1979).
