耐久年限 的英文怎麼說
中文拼音 [nàijiǔniánxiàn]
耐久年限
英文
maintenance-free life-
Sixthly, the monte - carlo method is used for calculating the failure probability of durable failure under different service time, and drawing a plot of relationship between failure probability and service time. according to the plot, the service life based a acceptable failure probability can be found easily
第六，用monte - carlo方法對不同使用年限耐久性失效概率進行計算，得到使用年限和失效概率的關系曲線，並由關系曲線得出氯離子侵蝕環境下鋼筋混凝土構件在指定可接受失效概率水平下的耐久壽命。For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。Durability and operating cautious
