赵州桥最大的科学贡献就是它“敞肩拱”的创举。

The greatest scientific contribution of Zhaozhou Bridge is its pioneering work of " open spandrel . "

在结构上，弧形平拱和敞肩小拱给人一种巨身轻灵、跃跃欲飞的动感。

Structurally speaking , the bow-shape big arc and the small round arcs on the shoulder make the bridge look light despite its bulk body and give you the feeling that it is about to fly away .

通过分析带式烧结机台车执行牵引装置的星轮和台车的力学关系，建立了台车无叠肩起拱的力学模型，提出了无叠肩起拱带式烧结机的力控制方法。

By analyzing the mechanics relation between the sprocket wheel and the pallets of the pallet draught device in a sintering machine , the non-arching mechanics model of the pallets was established and the force control method for the non-arching sintering machine was put forward .
