| 摘 要： | 对观测到的受星风或膨胀气壳包围的双星系统的PCyg谱线理论分析可精确测定其星风物质损失率．我们在计算这类星的理论谱线时，考虑了氢氦混合气体的多能级跃迁、轨道运动引起的密度非径向分布等因素，对轨道形状做了简化，所得结果是令人满意的．

| Abstract: | The mass loss rates of binary systems, enveloped in winds or expanding shells, can be accurately measured by analysing the P Cyg lines. As to calculate the lines, the multi-level transitions in mired gases of hydrogen and helium, and the non-radial density distribution caused by orbital motions are considered by us, but the orbits are simplified as circles. The results obtained are quite satisfactory. |
