Two . boat builders would suffer and towline , whip and harness makers would be left destitute 其二,造船工的生计会受影响,制作纤绳、鞭子及马具的工人将会陷入贫困。

On the slow weedy waterway he had floated on his raft coastward over ireland drawn by a haulage rope past beds of reeds , over slime , mud - choked bottles , carrion dogs . athlone , mullingar , moyvalley , i could make a walking tour to see milly by the canal 他乘了这条用一根纤绳拽着的木排,顺着涓涓流淌杂草蔓生的河道,涉过苇塘,穿过烂泥,越过一只只堵满淤泥的细长瓶子,一具具腐烂的狗尸,从爱尔兰腹地漂向海岸。

System imitation analysis in the time domain indicates that the amplitude and peak of displacement at the joint between cable and mast are both reduced , and the fatigue life of guyed mast is increased . adjusting the location of mr damper can efficiently reduce the displacement on the top of guyed mast induced by wind 仿真分析表明可以有效地减小桅杆结构纤绳与杆身连接处的位移响应的幅值与峰值,能提高结构的疲劳寿命,通过调节mr阻尼器的作用位置可以改善对桅杆顶部位移响应的控制效果。

The guyed mast structure is a high - rise system made up of soft cable and slim mast . the interaction between the inclined guys and the mast makes its nonlinear dynamics very complex . the damage probability of guyed mast is especially high under normal designing and constructing in civil engineering fields 桅杆结构是由柔索和细长的杆身组成的高耸结构,斜拉的纤绳和杆身使其非线性振动十分复杂,在正常设计、建造及材料情况下,桅杆结构破坏发生的比例之高在土木工程界是少见的。
