为了研究辐射对大陵五双星低温组分光谱的影响，本文用U.M.A.已被使用。改变了上边界条件，以考虑外部辐射场，并引入了一个自动程序，以防止数值振荡。为了模拟来自热分量的外部通量，我们使用了UMA采用的波长插值的Kurucz网格代码.由于二级恒星的Algoltype双星通常有深对流层，我们施加的条件，这些区域的熵必须是相同的照射和非照射模型。
In order to investigate the effects of irradiation on the spectra of the cooler components of Algol binaries, a modified version of the Upsalla Model Atmosphere code (U.M.A.) has been used. The upper boundary condition was changed to take into account the external radiation field and an automatic procedure to prevent numerical oscillations was introduced. In order to simulate the external flux from the hot component we have used the Kurucz grid interpolated for the wavelenghts adopted in U.M.A. code. Since secondary stars of Algoltype binaries normally have deep convective layers, we impose the condition that the entropy of these zones must be the same in the irradiated and in the non-irradiated models.
