摘　　要：光纤陀螺仪中的光纤环需要采用温度稳定性高的保偏光纤(PMF)。除了PMF预制棒的结构设计外,光纤内涂覆材料的性能对PMF温度稳定性也有重要的影响。讨论了内涂覆材料的参数、涂覆层的固化度对PMF温度稳定性的影响,并建议采用内涂覆层固化度控制的方法来获得温度稳定性良好的PMF。The fiber optic gyro-ring used in fiber optic gyroscope requires PMF with high thermal stability. Besides the structure design of the PMF preform the material performance of the inner coating also has important impact on the thermal stability of PMF. Therefore, the impact of the material parameters of the inner coating, the curing degree of the coating on the thermal stability of PMF is discussed, and the method that obtains PMF having good thermal stability by controlling the curing degree of the inner coating is proposed.
