Therefore , the study of calculating method on tube - structure piled raft foundation has great social effects and economical profits 因此，对筒体结构桩筏基础计算理论进行研究有着很大的社会效益和经济效应。
In the newsroom a group of people was standing by the television . there had been bombs on tubes and buses . someone was talking about al - qaeda 在新闻中心，有一群人站在电视机前。地铁和公共汽车上有人放炸弹了。有人谈到了基地组织。
In the last year almost 150 , 000 items have been left on tubes , buses and taxis , with mobile phones and books among the most - mislaid articles 去年之中约有15万项物品被遗忘在伦敦的地铁、巴士与计程车上，其中手机和书都列入最常遗失的物品之中。
This text is to specify the control on tube expanding rate and compare the calculation on tube expanding rate , based on above drawing up the control range of tube expanding rate for different material and meanwhile sum up the factors which influence the tube expanding quality 摘要对胀管率的控制进行了详细的论述，并对胀管率的计算方法进行了比较，从而提出了不同材料的胀管率的控制范围；同时对影响胀接质量的因素作了总结。
Indicated from the results : influenced by geometric parameters analyzed above , the effect on tube filler hollow floor is similar with box filler hollow floor ; though differing from section properties between these two structures , the bear bending rigidities in the two perpendicular directions are almost the same 结果表明:薄壁筒芯空心楼板受以上分析的各几何参数的影响效果与薄壁箱体空心楼盖很相似;虽然两种结构的截面特性不同,但抗弯刚度在两正交方向基本相同。
