摘　　要：光纤强度Weibull分布中的形状参数m及光纤的抗疲劳参数n可用于光纤使用寿命的估计,光纤断裂可靠性研究也需借助Weibull分布参数的计算。利用Matlab通用数学软件进行光纤强度的Weibull分布参数计算及推定时,精度高、速度快、作图方便,尤其在各设定的置信度区间进行分布检验,因秩表不完整很难判断时,只要熟练运用Matlab就可制做出各种分布的数值表用于检验。The shape parameter m and fatigue parameter n in the Weibull distribution of optical fiber can be used in the estimation of fiber lifetime, and the research of fiber reliability also needs for the calculation of Weibull distribution parameter. Using Matlab to calculate and presume the Weibull distribution parameters of fiber strength has features of fast, accurate, and easy to plot. Especially, when rank table is not complete for carrying out distribution checking in various set confidence intervals only skilled application of Matlab can the data table of various distribution be made for checking.
