摘　　要：阐述了通过把纳米级的二氧化硅微粒掺入光纤的聚合物涂层内能改进光纤长期机械特性。实验分析表明涂层添加物能显著降低光纤表面粗糙度的变化速率,其作用是抑制表面溶解过程。用这种方法可以延迟光纤疲劳转折的发生,并使零应力老化下的强度衰退降到最低限度。The paper describes that the addition of nanosized particles of fumed silica to the polymer coating of fused silica optical fiber is shown to improve long- term mechanical properties of the fiber.Experiment shows that the presence of the additive dramatically reduces the rate of development of surface roughness and that the effect of the additive is to suppress surface dissolution processes.By this method,it delays the onset of the fatigue transition and reduces the strength degra- dation due to zero stress aging.
