摘要
新的恒星临边昏暗线性经验公式精度高的原因之一可用几何学观点加以解释，其LTE推广与太阳观测和心宿二的临边昏暗系数测量能很好一致．
One of the reasons that the new stellar limb darkening linear empirical law ismore accurate can be explained from aspect of geometry. The LTE generalizationof the new law agrees to the observation results of the Sun and the Antares well.The condition under which two limb darkening zero order approximations (UD andFDD) could be applied is summarized in the paper.
