The construction unit when the tower crane foundation, must ensure that the endurance meets the design requirements, the strength of reinforced concrete at least the design value of 80%.
施工单位在做塔吊基础的时候，一定要确保地耐力符合设计要求，钢筋混凝土的强度至少达到设计值的80%。
Using the property of the monotonic degradation of the ship hull strength with time, the minimum value of the ship hull strength in the design lifetime can be easily determined.
利用船体梁强度的单调退化特性，确定在设计寿命内船体强度的最小值。
This value is used to compare the strength of materials, but a safety factor is applied when making design calculations, to bring the working stress well below the limit of proportionality.
此值被用来比较材料的强度，但是当设计计算时，要用一个安全系数，使工作应力低于比例限制。
