extradoses
基本解释
- n.拱背(拱洞的外弧面；外拱线)
英汉例句
- An arch with mutually supporting voussoirs that has a straight horizontal extrados and intrados.
有水平拱背和水平的内弧面的互相支撑的拱石的拱。 - By data fitting of FEA, an empirical formula of the limit pressure for elbows with local thinned area on inner wall of extrados has been attained.
由有限元计算结果数据拟合出了外拱内壁局部减薄弯管塑性极限内压的计算公式。 - The results of FEA method for cold-bending elbow predicted that the point of maximum stress is transferred from intrados to extrados with the increase of the wall thinning.
并应用有限元方法分析了冷弯弯头的应力状况，得出其最大应力发生点随着外拱处壁厚减薄量的增大而向外拱处转移。 - Then, based on the seismic response analysis of the extrados cable-stayed, influence of high-order vibration modes on dynamic behavior of the bridges is analyzed.
在分析矮塔斜拉桥地震反应的基础上，通过引入振型贡献率的概念，分析了高阶振型对矮塔斜拉桥动力性能的影响； - the method of reducing load on extrados
