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.

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。

When strength degenerates, reliability decreases with time more obviously, and the failure rate has the feature of a bathtub curve.

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。
