说明：  1.JC_method_ty.m是JC法可靠度计算的通用函数程序，具体使用方法见下面的实例操作。 2.beta_time是时变可靠度的计算程序，程序是针对文件夹中“使用寿命计算实例.doc”里面的案例进行的计算。程序中间通过引用JC_method_ty.m函数来计算每个时间点的可靠度，并进行图形绘制。
(1. JC_method_ty. M is the general function of JC method of reliability calculation program, see below the specific method of use an instance of the operation. 2. Beta_time is time-varying reliability calculation procedures, procedures for folder service life calculation example. Doc inside the case calculation.Program by reference among JC_method_ty. M function to calculate the reliability of each point in time, and graphics.)
