Just then a sort of brightness fell upon me in the barrel and looking up , i found the moon had risen , and was silvering , the mizzen - top and shining white on the luff of the fore - sail and almost at the same time the voice of the look - out shouted land ho 就在这时，一道光亮射进桶内，照到了我身上，而当我抬头望时，发现月亮已经升起来了，照得后桅的顶部银光闪闪，前桅帆的顶上也白花花的几乎与此同时，观望的声音喊起来： “陆地嗬！ ”
Hence there were still faithful men on board when dick returned , one after another of the trio took the pannikin and drank - one to luck ; another with a here s to old flint ; and silver himself saying , in a kind of song here s to ourselves , and hold your luff , plenty of prizes and plenty of duff 当狄克回来之后，三个人一个接一个地端起杯子喝上了一个说“祝好运”另一个说“这一口为老弗林特” ，而西尔弗他本人则用唱歌似的腔调说， “这一口为我们自己，占住上风，广进财源，大吃肉馒头。 ”
Combining the design of portal crane luffing mechanism , this paper set up the math model independently and synthetically of the single boom system with compensating pulley and level - balancing weight . use genetic algorithms to optimize the model , the calculated results show as follows the genetic algorithms is effective and manipulable , the synthetically optimize is best than independently optimize . the optimization program of luffing mechanism was build , and this will be a useful tool in the design of crane 结合门座起重机变幅机构的设计，建立了导向滑轮补偿系统和杠杆? ?活对重臂架自重平衡系统独立模型和综合模型的未平衡力矩最小的优化问题，结合遗传算法对它进行了优化，结果证实了该算法的有效性和可行性，表明了综合优化比独立优化更能提高优化的准确性。
The optimization design of portal crane luffing system is the result that optimization design apply in engineering design , but because the engineering problem is complicated , the traditional optimization design method is not very successful . in this paper , the optimization of the single boom system with compensating pulley and level - balancing weight is studied . in the math model , the wire rope length encircled in the pulley and reel is considered , that enhance the optimization precision and introduce genetic algorithms , combine engineering tightly , that settle the difficult in the traditional optimization successfully 门机变幅系统优化设计是将优化设计方法应用于工程设计中的产物，但由于设计工程问题的复杂性，采用传统的优化设计方法优化的成功率及效果并不理想。本文以单臂架变幅机构导向滑轮补偿系统和杠杆? ?活对重臂架自重平衡系统的独立模型及综合模型为研究对象，考虑了滑轮和卷筒处包绕的钢丝绳长度变化，从而提高了优化模型的精度，同时引进一种新型优化算法? ?遗传算法，紧密结合工程实际，较为圆满的解决优化过程中存在的问题。
They were , says mr stephen , and the end was that the men of the island , seeing no help was toward as the ungrate women were all of one mind , made a wherry raft , loaded themselves and their bundles of chattels on shipboard , set all masts erect , manned the yards , sprang their luff , heaved to , spread three sheets in the wind , put her head between wind and water , weighed anchor , ported her helm , ran up the jolly roger , gave three times three , let the bullgine run , pushed off in their bumboat and put to sea to recover the main of america “此语不差” ，斯蒂芬先生曰， “其结果，本岛男子发现负情女子异口同声，无可救药。遂建造舟筏，携家财登船，桅杆尽皆竖起，举行登舷礼，转船首向风，顶风停泊，扬起三面帆，在风与水之间挺起船首，起锚，转舵向左，海盗旗迎风飘扬，三呼万岁，每次三遍，开动舱底污水泵，离开兜售杂物之小舟，驶至海面上，航往美洲大陆。 ”
