摘　　要：对直接挤出法制备梯度型聚合物光纤的工艺流程进行了分析,根据双组分混合物折射率计算理论和梯度型聚合物光纤径向折射率分布函数,计算了梯度型聚合物光纤单位长度中所含掺杂剂的质量;将非稳态扩散理论和有限差分法结合起来,对梯度型聚合物光纤折射率分布的形成进行了理论研究,建立了数学物理模型,得到描述梯度型聚合物光纤径向折射率形成的普遍性近似方法.The preparation method for graded index polymer optical fiber was analyzed using co-extrusion methods. According to the calculation theory about two refractive index and the function of refractive index distribution of the GI-POF, the dopants＇ mass was calculated. Based on the unstable diffusion theory and finite difference method, the forming of refractive index distribution was described and the mathematical model was obtained. The general approximate way to describe the forming of refractive index distribution of the GI-POF was attained.
