使用寿命期 meaning in Chinese
useful life period
Examples
- So one might make wrong purchase decision if he fails to consider the total costs within product ' s life cycle ( i . e lcc )
因此，如果不从整个使用寿命期内综合考虑产品的全部成本(即全寿命期成本) ，就极有可能做出错误的购置决策。 - Traditional concept of cost is always restricted in certain aspect of manufacture or commercial operation , but seldom covers through product ' s whole life span . this often leads to consumer ' s emphasis only on reducing the purchase price while ordering product
传统的成本概念往往局限于产品的制造或运营的某一环节，而很少涵盖产品的整个使用寿命期，这往往就会导致用户在购置产品时只着眼于如何尽量压低购置价格。 - Although strict design calculations are made to guarantee the members have sufficient strength in their work life , yet dash and improper loads may damage them during construction and in service . these damages include elastic - plastic bending and local dent in the walls of the tube . in addition , corrosive medium such as atmosphere and contaminated water can also bring corrosion damage in the walls of the tube
虽然都经过严格的设计计算，以保证其在使用寿命期内有足够的强度，但在安装施工和使用期间，往往因受到冲撞和非正常荷载而产生弹塑性弯曲和凹陷等损伤，此外大气、受污染的水分等腐蚀性介质也可能在管壁上产生腐蚀损伤。 - One is based on reliability theory , and the other is on both reliability theory and economic optimization . corresponding assessment criterions for remaining service life of existing concrete structures were put forward . according to the characteristic of concrete structures , a method was suggested to calculate the reliability of existing concrete structures
根据在役结构的特点，基于可靠性和经济优化相结合建立了一种在役混凝土结构最优剩余使用寿命预测的优化模型，并提出了在役混凝土结构剩余使用寿命的评估准则；结合在役混凝土结构荷载与抗力随时间变化的特点，分析了在役结构动态可靠度的变化，并推导出在役混凝土结构在剩余使用寿命期内的可靠度计算公式。
