The results show that the maximum achievable repeater spacing is 17km over that calculated using a conventional worst-case design approach for a premature failure rate of 0.1%.

结果表明，当系统先期失效率为0.1％时，按统计法设计的最大中继距离可以比传统的最坏值法加长17公里。

Corrosion of rebar in concrete is one of the most frequent causes of their premature failure. Measurements of corrosion rate and condition can be used to estimate remaining load and durability.

混凝土中钢筋的腐蚀是混凝土结构破坏和修复的主要原因之一，钢筋腐蚀速率的监测和腐蚀状况的判定可以为钢筋混凝土结构的剩余载荷和结构的耐久性提供基础数据。
