Rigging and fitting my Mast and Sails; for I finish'd them very compleat, making a small Stay, and a Sail, or Foresail to it, to assist, if we should turn to Windward; and which was more than all, I fix'd a Rudder to the Stern of her, to steer with; and though I was but a bungling Shipwright, yet as I knew the Usefulness, and even Necessity of such a Thing, I apply'd my self with so much Pains to do it, that at last I brought it to pass; though considering the many dull Contrivances I had for it that sail'd, I think it cost me almost as much Labour as making the Boat.

此外,我还配上小小的桅索以帮助支撑桅杆。我在船头还做了个前帆,以便逆风时行船。尤其重要的是,我在船尾还装了一个舵,这样转换方向时就能驾御自如了。我造船的技术当然不能算高明,然而知道这些东西非常有用,而且是必不可少的,也就只好不辞辛劳,尽力去做了。在制造过程中,我当然几经试验和失败。如果把这些都计算在内,所花费的时间和力气,和造这条船本身相差无几。

In accordance with discrete, non-symmetry and time-delay feedback neural networks, we provide some theoretical criteria to judge the stability for designing the networks. On continuous feedback networks, we built an algorithm to estimate the convergence region. On the HNN feedback networks, an effective optimization algorithm based on the annealing strategy and the chaotic neural network is presented, and some disciplinary conclusions are provided to guide the selection of parameters. Simulation results on benchmark problems demonstrate that the performances of our algorithm are distinctly superior to those of the classic HNN based on gradient descend and stochastic optimization methods based on probabilistic distribution.

I know how to hurt I know how to kill I know what to show And what to conceal I know when to talk And I know when to touch No one ever die from wanting to much The world is not enough But it is such a perfect place to start, my love And if you're strong enough Together we can take the world apart, my love People like us Know how to survive There's no point in living If you can't feel the life We know when to kiss And we know when to kill If we can't have it all Then nobody will The world is not enough But it is such a perfect place to start, my love And if you're strong enough Together we can take the world apart, my love I - I feel sick I - I feel scared I - I feel ready I - And yet unprepared The world is not enough But it is such a perfect place to start, my love And if you're strong enough Together we can take the world apart, my love The world is not enough The world is not enough

今天和一群人看了加勒比海盗2,天哪,那个盗版DVD翻译的字幕实在太差了。害得我剧情都没有理解清楚,只知道大概就是那个"章鱼男"要和主人公们抢一个心脏。其中一位在我身边的观众估计是第1部没有看,居然当最后一幕巴博萨船长出现时,奇怪的问道:这是谁啊?我晕,估计他也懒得补看第一部了。看不懂剧情挺遗憾,不过我无所谓,反正我把这片定义为视觉大餐而已,没想一定要弄懂什么剧情。从全片角度来看看来"加勒比海盗"要走"黑客帝国"、"星球大战"的路线--第一集试探市场反应,第二集留个悬念,第三集大收尾。整个续集来看,除了又两段搞笑成分较浓的动作戏外,没感觉什么新意了。影片前半部分的那段丛林戏,跟"金刚"几乎是一摸一样。同时看过这两部电影的人不知会作何感想。表演上还算到位,Johnny Deep的表现最为出色,就是暂时不知道最后一集他怎么出场。两部加勒比海盗的配乐都相当出色,颇有"角斗士"的味道。视觉大片而已嘛,不计较太多,看看而已,一笑而过。。。

After introducing some basic results from ergodic theory, two probIems related to the dynamical system are studied: first the existence of absolute continuous invariant measures, and then their computation.

From just began to do a website to calculate to now will also have 56 years, remembered 2 years having individual homepage, that is whats do not understand, had not been in charge of on the free space that did page of a few Html to put Hu Yi with Dreamweaver, do not know to have tally even this thing, of course more do not know to be able to bring discharge through Baidu, feel amused namely at that time, also had not wanted to be able to make this group later.

从刚开始做网站到现在算来也有五六年了吧,记得02年就有了个人主页,那是什么都不懂,用Dreamweaver做了几十个html页面放到虎翼的免费空间上就没管过,甚至都不知道有计数器这个东西,当然更不知道可以通过百度带来流量了,当时就是觉得好玩,也没想过以后会做这一行。
