摘　　要：从程函方程出发,通过建立物理模型,利用折射率分布函数和数值微分法求解光纤中的光线轨迹,并经过计算机模拟,得出光线轨迹能够很好的和实际光线轨迹相吻合。From eikonal equation, we calculate the ray trace in fiber with refractive index distribution function and numerical differentiation by creating a physical model. At last, we, by computer simulation, draw a conclusion that the simulant ray trace correspond well with the ray traces in reality.
