不一样，泰产的是东南亚出的，一般只供应亚太地区，而且算是分厂吧，只是买了哈雷的生产线，美国产的是总厂的，有自己的知识产权，基本都是人工装配的。哈雷是个品牌,全称说哈雷带维森。是美国的品牌。

哈雷泰国工厂正式启用，相比美国生产哈雷泰产售价降低30%去年哈雷就宣布在泰国建立自己的工厂，而当时的负责人声称泰国工厂将采用CDK的形式生产，部分主要部件依然是由美国工厂生产，然后送由泰国工厂组装。

美产哈雷和泰产哈雷的趋势

针对国内市场来说，很多人都在质疑，由东南亚地区制造的摩托车会不会在质量上有所降低。不过放眼目前在国内销售的车型来看，除了一些车型在动力和排放上受到限制，摩托的的质量并没有多少差异，反而售价会降低很多。

试想如果哈雷真的把多款车型移至东南亚地区生产，那么销售价格也许会降低很多，这对于国内摩友来说，无疑是一件好事但是这样也大大降低了哈雷摩托车的制造成本，从而降低它的售价来获得更多的竞争力。

博雅上海牛顿不仅以力学三大定律和万有引力理论开创了经典物理学时代，而且也是数学领域中微积分学的创始人。Much of today's science of physics is based on Newton's discovery ofthe three laws of motion and his theory of gravity Newton also developed one of the most powerful tools of mathematics It is the method we call calculus “我之所以看得远，是因为我站在巨人的肩膀上”这些巨人是谁呢？伽俐略、哥白尼等Late in his life, Newton said of his work: "If I saw further than other men, it was because I stood on the shoulders of giants " One of those giants was the great Italian scientist, Galileo Galileo died the same year Newton was born Another of the giants was the Polish scientist Nicholas Copernicus He lived a hundred years before Newton Copernicus had begun a scientific revolution It led to a completely new understanding of how the universe worked Galileo continued and expanded the work of Copernicus Isaac Newton built on the ideas of these two scientists and others He found and proved the answers for which they searched 牛顿喜欢什么呢？喜欢制作小东西，喜欢发明新方法去回答问题，解决问题。Isaac Newton was born in Woolsthorpe, England, on December twenty-fifth, sixteen forty-two He was born early He was a small baby and very weak No one expected him to survive But he surprised everyone He had one of the most powerful minds in history And he lived until he was eighty-four Newton's father died before he was born His mother married again a few years later She left Isaac with his grandmother The boy was not a good student Yet he liked to make things, such as kites and clocks and simple machines Newton also enjoyed finding new ways to answer questions or solve problems As a boy, for example, he decided to find a way to measure the speed of the wind 你会想办法使用各种方法来测风力吗？On a windy day, he measured how far he could jump with the wind at his back Then he measured how far he could jump with the wind in his face From the difference between the two jumps, he made his own measure of the strength of the windStrangely, Newton became a much better student after a boy kicked him in the stomach The boy was one of the best students in the school Newton decided to get even by getting higher marks than the boy who kicked him In a short time, Newton became the top student at the school 牛顿曾经在农场干活，后来，到剑桥大学完成了5年的数学学习。Newton left school to help on the family farm It soon became clear, however, that the boy was not a good farmer He spent his time solving mathematical problems, instead of taking care of the crops He spent hours visiting a bookstore in town, instead of selling his vegetables in the market An uncle decided that Newton would do better as a student than as a farmer So he helped the young man enter CambridgeUniversityto study mathematics Newton completed his university studies five years later, in sixteen sixty-five He was twenty-two years old 牛顿为避免瘟疫又回到农场，用学过的数学去研究宇宙，去设计更多的实验方法。可见重要的，不仅是知识，而是如何采取各种方法去获得事物的规律，从而学习知识，或发现规律。At that time, a deadly plague was spreading across England To escape the disease, Newton returned to the family farm He did more thinking than farming In doing so, he found the answers to some of the greatest mysteries of science Newtonused his great skill in mathematics to form a better understanding of the world and the universe He used methods he had learned as a boy in making things He experimented Then he studied the results and used what he had learned to design new experiments 用数学方法测量固体物中物料的过程中，他发明了积分。Newton's work led him to create a new method in mathematics for measuring areas curved in shape He also used it to find how much material was contained in solid objects The method he created became known as integral calculus 从发现苹果落地，到探究测量，使他发明了万有引力！并做实验发现与之相关的因素。One day, sitting in the garden, Newton watched an apple fall from a tree He began to wonder if the same force that pulled the apple down also kept the moon circling the earth Newton believed it was And he believed it could be measured He called the force "gravity " He began to examine it carefully He decided that the strength of the force keeping a planet in orbit around the sun depended on two things One was the amount of mass in the planet and the sun The other was how far apart they were Newton was able to find the exact relationship between distance and gravity He multiplied the mass of one space object by the mass of the other Then he divided that number by the square of their distance apart The result was the strength of the gravity force that tied them to each other Newton proved his idea by measuring how much gravity force would be needed to keep the moon orbiting the Earth Then he measured the mass of the Earth and the moon, and the distance between them He found that his measurement of the gravity force produced was not the same as the force needed But the numbers were close Newton did not tell anyone about his discovery He put it aside to work on other ideas Later, with correct measurements of the size of the Earth, he found that the numbers were exactly the same 牛顿关于白光由色光组成的发现为近代物理光学奠定了基础。并且他将玻璃换成透镜，做成了牛顿反射式望远镜。Newton spent time studying light and colors He used a three-sided piece of glass called a prism He sent a beam of sunlight through the prism It fell on a white surface The prism separated the beam of sunlight into the colors of a rainbow Newton believed that all these colors -- mixed together in light -- produced the color white He proved this by letting the beam of rainbow-colored light pass through another prism This changed the colored light back to white light Newton's study of light led him to learn why faraway objects seen through a telescope do not seem sharp and clear The curved glass lenses at each end of the telescope acted like prisms They produced a circle of colored light around an object This created an unclear picture A few years later, Newton built a different kind of telescope It used a curved Isaac Newton invented a telescope that used a mirror instead of a lens To this day, they are call Newtonian telescopesmirror to make faraway objects seem larger Light reflected from the surface of the mirror, instead of passing through a curved glass lens Newton's reflecting telescope produced much clearer pictures than the old kind of telescope 天文学家哈雷促成了牛顿理论的问世。1687年，他的划时代的巨著《自然科学的哲学原理》问世。牛顿开创的物理学体系占主导位置长达二百多年，成为很多科学进步和发现的基础。Years later, the British astronomer Edmund Halley visited Newton He said he wanted Newton's help in finding an answer to a problem no one had been able to solve The question was this: What is the path of a planet going around the sunNewton immediately gave Haley the answer: an egg-shaped path called an ellipse Halley was surprised He asked for Newton's proof Newton no longer had the papers from his earlier work He was able to recreate them, however He showed them to Halley He also showed Halley all his other scientific work Halley said Newton's scientific discoveries were the greatest ever made He urged Newton to share them with the world Newton began to write a book that explained what he had done It was published in sixteen eighty-seven Newton called his book "The Mathematical Principles of Natural Philosophy" The book is considered the greatest scientific work ever written 书中的三大力学理论：第一定律：物体在没有外力作用的情况下会保持原有的状态，静止状态或匀速直线运动状态。物体保持这种运动状态的特性，称为惯性。

哈雷彗星每76年到访地球一次，这个时间是谁推算出来的？

哈雷彗星上次来的时候我还是个孩子，其实有肉眼观测的条件，但是很可惜错过了。我想努力活到2061年，垂垂老矣的我能看到哈雷彗星，不要再错过。

来自百度。下次看到大概是这样子。

上一次哈雷彗星回归远在1986年，彼时答主的父母互相还不认识……好吧这并不是重点。当年哈雷彗星的最大亮度并不高（仅有21等），而且在北半球的观测条件也不怎样，对比此后出现的几颗真·大彗星（百武彗星@1996，海尔波普彗星@1997，麦克诺特彗星@2007，爱喜彗星@2011），哈雷彗星简直就是被吊打的节奏。

（1986年的哈雷彗星，哎，我都没眼看了……）

可是人家依然很著名，而且可能是最著名的一个，这说明不是简单的亮度或者是观赏性问题了。

哈雷彗星和以上提到的大彗星对比，最独特的地方就是她属于短周期彗星（回归周期约76儒略年），而其余四颗据测算皆为长周期彗星（回归周期200+儒略年）。

回归周期短有个好处，就是能和人类混个脸熟嘛！

《春秋》：秋七月，有星孛入于北斗

《史记·始皇本纪》：始皇七年，彗星先出东方，见北方；五月见西方，十六日

据中国天文学家朱文鑫考证，公元前240年至1910年间在中国共有29次哈雷彗星的记录。

既然暂时认不了彗星，咱们说点别的。17世纪初开普勒根据详尽的火星观测记录总结出了描述天体运动的「开普勒三大定律」，被后世尊为「天空立法者」。但定律背后的本质是什么，开普勒之后的数十年间没有人能够解答。

直到牛逼顿和他的《自然哲学的数学原理》登上历史舞台。说起这个，不得不提到另一位英国科学家——埃德蒙·哈雷。没错，就是哈雷彗星那个哈雷。事情的经过大致是这样的：

哈雷就天体运动的一些谜团前往剑桥求助牛顿牛顿说艾玛这玩意儿我五年前就弄懂了哈雷：「Talk is cheap, show me the code」牛顿：吼啊！……咦明明就在这里……没事我再算一遍然后寄给你呗~

这之后究竟是牛顿自己停不下来还是因为哈雷的怂恿与鼓励我暂时不做考证，反正不会影响结果——牛顿用两年时间完成了《原理》的编写，最后在哈雷的帮助下成功出版。

至此科学家们手里有了新的武器——牛顿力学，可以向历史上的彗星记录发起挑战了。哈雷立马使用牛顿的方法分析了1337年至1698年间出现过的彗星，并发现1531年、1607年和1682年的彗星有非常相似的轨道要素。哈雷猜想这三次记录很可能是指向同一颗彗星，如果猜想成立，便意味着彗星会在将来某个时间再度回归。在考虑行星摄动的情况下，哈雷估算这颗彗星将会在1758年年末或者次年年初回归。

这大概是科学史上最重要的一次预言（之一），普通公众可能只是惊讶于能够预测数十年后的天象，而科学家们非常明白，这是对新武器最直接的检验。最终，随着彗星的如期回顾，牛顿力学经受住了一次重大考验，名声大噪，彗星也顺理成章被冠以「哈雷」之名，编号1P/Halley。

所以说哈雷彗星的背后承载着太多历史，这或许是她如此著名的原因之一。然而公众很可能并不知道我上面说的种种。历史上哈雷彗星也曾是末日死神般的存在：1910年哈雷彗星回归时，彗尾扫过地球，当时的光谱分析显示彗尾中含有氰，使得有天文学家担心彗尾的气体会因此渗入地球，导致全球生物灭绝。尽管其他天文学家很快便出来辟谣（抛开剂量谈毒性就是耍流氓），但依旧引发了公众的恐慌，防毒面具大卖这或许是哈雷彗星著名的另一个原因。
