While we were in this condition, the men yet labouring the oar to bring the boat near the shore, we could see then our boat mounting the waves, we were able to see the shore, a great many people running along the shore to assist us when we should come near, but we made but slow way towards the shore, nor were we able to reach the shore, till being past the light-house at Winterton, the shore falls off to the westward towards Cromer, and so the land broke off a little the violence of the wind: Here we got in, and though not without much difficulty got all safe on shore and walked afterwards on foot to Yarmouth, where, as unfortunate men, we were used with great humanity as well by the magistrates of the town, who assigned us good quarters, as by particular merchants and owners of ships, and had money given us sufficient to carry us either to London or back to Hull, as we thought fit.

尽管我们处在这种情况，水手们还是奋力把小艇向海岸划去。我们能够看见，当小艇随浪尖升起时，我们已能看到海岸了，还看见有许多人在岸边跑动，等我们小艇靠岸时救助我们。但小艇前进的速度很慢，而且怎么也无法靠岸。最后，我们小艇竟飘过了温特顿岬角的灯塔。海岸已经处在克罗默西边的位置。这样，陆地削弱了一点风势，在这里我们全体安全上了岸，虽然也是克服了许多困难。上岸后我们步行至大雅茅斯。我们这些不幸者照例受到了这个城镇的社会贤达们非常人道的接待；他们通过一些商人和船主妥善安置我们住宿，还为我们筹足了旅费，以便按我们的意愿送我们去伦敦，或送我们回赫尔市。

While we were in this Condition, the Men yet labouring the Oar to bring the Boat near the Shore, we could see, hen our Boat mounting the Waves, we were able to see the Shore, a great many People running along the Shore to assist us when we should come near, but we made but slow way towards the Shore, nor were we able to reach the Shore, till being past the Light-House at Winterton, the Shore falls off to the Westward towards Cromer, and so the Land broke off a little the Violence of the Wind: Here we got in, and tho' not without much Difficulty got all safe on Shore and walk'd afterwards on Foot to Yarmouth, where, as unfortunate Men, we were used with great Humanity as well by the Magistrates of the Town, who assign'd us good Quarters, as by particular Merchants and Owners of Ships, and had Money given us sufficient to carry us either to London or back to Hull, as we thought fit.

尽管我们处境危难，水手们还是奋力向岸边划去。当小艇被冲上浪尖时，我们已能看到海岸了，并见到岸上有许多人奔来奔去，想等我们小艇靠岸时救助我们。但小艇前进速度极慢，而且怎么也靠不了岸。最后，我们竟划过了温特顿灯塔。海岸由此向西凹进，并向克罗默延伸。这样，陆地挡住了一点风势，我们终于费了九牛二虎之力靠了岸。全体安全上岸后，即步行至雅茅斯。我们这些受难的人受到了当地官员、富商和船主们的热情款待；他们妥善安置我们住宿，还为我们筹足了旅费。我们可以按自己的意愿或去伦敦，或回赫尔。

However, to establish global convergence for these latter methods, one must enforce either sufficient decrease conditions (the Armijo-Goldstein-Wolfe conditions)or a fraction of Cauchy decrease condition - all of which rely on explicit numerical function values, as well as explicit approximations to the directional derivative at the current iterate.

但是，为了保证后面方法的全局收敛，必须有足够的减少条件（Armijo-Goldstein-Wolfe条件）或者部分柯西减少条件——它们全都依赖于外在的数值函数值，就和在当前迭代逼近方向导数一样。
