第3章在对零部件故障浴盆曲线分析的基础上，探讨零部件回收率的变化规律，并通过维修数据仿真模拟零部件回收量分布概率。
The recycling rate of reusable spare parts and spare parts U-shape curve is analyzed in Chapter 3 with simulating distribution by data of after-sale activity.
针对国内斯特林制冷机可靠性处于浴盆曲线前端的现状，提出当前斯特林制冷机工程化解决加工、装配误差等引起早期失效的问题。
As the Stirling cryocoolers' reliability is at foreside of bathtub curve, the earlier failure problem of refrigerator, which results from manufacture and assembly process, should be solved.
强度退化时，可靠度随时间降低较为明显，失效率具有“浴盆”曲线的特征。
When strength degenerates, reliability decreases with time more obviously, and the failure rate has the feature of a bathtub curve.
