摘　　要：光线在恒星附近传播时,理论计算的偏折角有两个结果.一个结果由Newton引力论计算而得,另一个由Einstein广义相对论计算得到.后者是前者的两倍.对于与人类最近的恒星太阳,数值计算结果分别为0.875″(角秒)和1.75″,本文给出这两个结果的详细计算过程.日食发生时是检测理论结果的良好时机,迄今为止所有的实验观测结果支持相对论对太阳光线偏折角的计算.When a light goes over through the surface of a star,there will be a deflection angle in two kinds of results. One is derived from Newton＇s gravitation theory, and the other is derived from Einstein＇s theory of general relativity. The latter is twice of the former. As for the Sun,the nearest star to the human,the numerical results are 0. 875＂ and 1.75＂. Here is the computing progress in detail. It is the due time to proof-test the inclusion when a solar eclipse is appearing. By far all the experimental information is in agreement with the general relativity.
