分析中，建模时端板与柱翼缘，角钢和T形连接件与柱翼缘和梁翼缘，螺栓头与相邻板件间，螺栓杆与孔壁间都设置了反映边界状态的接触单元。

In the commonly used positive cycle of drilling, the mud pump is to rinse the surface with water medium ─﹑ mud or polymer washing fluid at a certain pressure, through the high-pressure hose taps and drill column ﹑ center hole in the bottom of the direct-drill in order to achieve Cooling ﹑ be cutting down the drill cuttings removal and transport to the surface purpose.

在常用的正循环钻探中﹐泥浆泵是将地表冲洗介质─清水﹑泥浆或聚合物冲洗液在一定的压力下﹐经过高压软管﹑水龙头及钻杆柱中心孔直送钻头的底端﹐以达到冷却钻头﹑将切削下来的岩屑清除并输送到地表的目的。

Furnace door movements through rolling ro-und in the upper and lower guide rail rolling realized,ens-ures that when furnace door closed seal anastomosis betweenfurnace door and furnace,ensured that the opening will not be in the process of friction injury masonry,furnace door and the car actionboth passed by the motor worm gear redu-cer,to provide the chain of transmission,electromagnetic brake and equipped with appropriate adjustments.

炉门升降通过滚动轮在导轨上下滚动实现，既保证了关闭炉门时炉门炉体间的吻合密封，又保证了在开启的过程中不会磨擦损伤砌体，炉门及台车运动均是由电动机通过蜗轮蜗杆减速机，链条传动来提供的，并装有电磁制动器进行适当的调整。

Iron production was revolutionized in the early eighteenth century when coke was first used instead of charcoal for refining iron ore. Previously the poor quality of the iron had restricted its use in architecture to items such as chains and tie bars for supporting arches, vaults, and walls.

自从焦炭第一次被铁矿石中提炼出的木炭所取代时，铁产品早在18世纪就已经被彻底改革了，原来的质量差的铁已经在以下这些领域的有限的被使用，如铁链、支撑系杆、拱顶以及墙壁。
