The initial retrofit consisted of removing the gaps between the stringer flange and floor beam by providing shims . 最初的修复工作是通过垫片来消除纵梁翼缘和横梁之间的间隙。
The second crack is a crack originating at the groove weld toe of the column flange-girder flange connection . 第二种是产生于立柱翼缘与主梁翼缘连接处的坡口焊缝焊趾处的裂纹。
The crack surfaces in the web and flange were subjected to visual examination in order to evaluate crack growth regions . 为了估计各裂纹扩展区，对翼缘和腹板的裂纹表面进行了宏观检验。
The behavior and performance of the cracked flange plates suggest that good levels of fracture toughness exist in the a 517 steel . 开裂的翼缘板的性能及使用状态说明A517钢的断裂韧性良好。
These cracks occurred at either the beam flange or in the column flange depending on the reentrant corner weld angle . 这些裂纹视凹形焊角的不同，或者出现在横梁翼缘上，或者出现在立柱翼缘上。
At the top flange there would be enough slack so that no relative twist of any significant magnitude would be introduced into the girder web . 在上翼缘处有足够的松动，因而在主梁腹板上并不会引起很大的相对扭转。
A reliable machine shop can cut away a small amout of metal from the aft side of the mounting flange so that the lens will set closer to the film platen . 可以请经验丰富的机械加工车间从安装凸缘的后部切削掉少量的金属，这样就能使透镜更加靠近胶片平面。
Visual observations showed that a horizontal displacement in the longitudinal direction of the bridge developed between the tie girder and the top flange of the floor beam at the end connection . 肉眼观察表明：在端节点处的系梁和横梁上翼缘之间产生一种沿桥梁纵向的水平位移。
Of course , the unit can be mounted using flange hole 当然，也可利用法兰孔安装。
