摘　　要：从含有14个后牛顿参数的太阳度规张量出发,采用一套迭代的方法,推导出了太阳单参考系下的二阶后牛顿光线方程;当其中所含的参数取特定的值时,得到广义相对论中的二阶后牛顿光线方程;当忽略高于1 c4 的项时。The post-post-Newtonian equations of light ray in one single frame of reference (the solar reference frame) were deduced from the solar metric tensor with fourteen post-Newtonian parameters. A kind of iterative method was used. When the parameters took some given values, the equations reduced to the post-post-Newtonian equations of light ray in general relativity. When the terms higher than 1/c4 were neglected,the post-post-Newtonian equations of light ray reduced to the classical post- New-tonian equations of light ray.
