摘　　要：目的提出产品定寿与延寿中应注意的5个问题,为产品延寿和寿命预测提供一些思路。方法在分析产品及其寿命周期环境特点的基础上,结合产品寿命研究及寿命周期故障情况,并借鉴国外相似产品贮存条件与寿命情况。结果产品寿命受贮存期间的温度、湿度、含氧量等环境条件和执勤过程中的环境条件影响,与产品复杂程度有关,并最终体现在时间效应上。结论应增强"产品设计重在防护"思维,做好寿命准确分析预测需要长时间的心理准备,在实施中坚持理论与实践相结合。Objective Five problems were summarized in order to put forward some consideration to prolong and forecast product life. Methods Firstly,product and its environment characteristics in life cycle were analyzed. Secondly,the experience of life and faults in domestic product were summarized. Thirdly,storage condition and life information of oversea similar products were consulted. Results Product life was affected by environment conditions,such as instance temperature,humidity and oxygen in its storage place or the condition of keeping as armaments. And it was related to the complexity of products. At last it was reflected in time effect. Conclusion The opinion of ＂ Emphasized protection in product design＂ should be enhanced,and we should get ready to precisely forecast product life in a long-term view,and persist in combining theory and practice in future study.
