Towards evening the mate and boat-swain begged the master of our ship to let them cut away the foremast, which he was very unwilling to: But the boat-swain protesting to him, that if he did not, the ship would founder, he consented; and when they had cut away the foremast, the main-mast stood so loose, and shook the ship so much, they were obliged to cut her away also, and make a clear deck.
临近傍晚，大副和水手长请求我们的船长让他们砍掉船头第一根桅杆；船长当然是很不愿意干的。但水手长坚持说，如果船长不这样做，船就会被风浪击沉；船长同意了。当他们把这根桅杆砍掉，主桅杆就站立不稳，船也随着剧烈摇晃，他们又只得把主桅杆也砍掉。这样就只剩下一个空荡荡的甲板了。

After they had enjoyed fair winds and weather for a season, they were en－countered many times with cross winds and met with many fierce storms with which the ship was shroudly shaken, and her upper works made very leaky; and one of the main beams in the midships was bowed and cracked, which put them in some fear that the ship could not be able to perform the voyage.
至于那根弯曲的主桅杆，因为船上的乘客们从荷兰带了一个巨大的铁螺钉，所以可以用它把那根桅杆复位，然后身兼木匠的船主保证他可以用一根固定在下层甲板上的柱子撑在它的下面，其他方向也绑好，这根桅杆就可以安全使用了。

Furthermore, the parametric vibration of guyed mast analyses and its control method is proposed. Finally, the wind tunnel experiment of guyed mast was carried out, and the test results were examined. Through the experiment, the dynamic characteristics of guyed mast are well understood, and the proposed method is this paper is verified.
并进一步分析了桅杆结构参数振动的特性及其控制方法，通过对桅杆结构风洞试验的分析，了解了桅杆结构在实际工作状态下的动力特性，并证明目前理论的正确性。

The guyed mast structure is made of soft cables and slender mast shaft, which dynamic characteristics are very complicated due to its large displacement and nonlinearity. Because its complicated theory is not fully understood yet, the damage probability is relatively high under normal design, construction and material.
桅杆结构是由纤绳和杆身所组成，其大变形及几何非线性使得其动力特性十分复杂，在正常设计、建造及材料情况下，桅杆破坏发生的比例之高在土木建筑中是罕见的，这主要是因为桅杆结构复杂的工作机理尚未完全被揭示。
