我们在包含详细的半经验大气的模型中考虑太阳振荡的大气行为。通过对辐射场的一致处理，推导出径向和非径向振荡方程。这些方程在径向灰色情况下求解；结果表明，偏离爱丁顿近似对振荡特性影响很小。给出了非径向情况的初步结果，表明当水平波长上的光学厚度为 1 或小于 1 的量级时，与爱丁顿近似有很大偏差。
We consider the atmospheric behaviour of solar oscillations in a model including a detailed, semi-empirical atmosphere. Equations of radial and non-radial oscillation, with consistent treatment of the radiation field, are derived. These equations are solved in the radial, grey case; the results show that departure from the Eddington approximation has little effect on the properties of the oscillations. Preliminary results are presented for the non-radial case, indicating substantial deviations from the Eddington approximation when the optical thickness across a horizontal wavelength is of the order of or less than unity.
