昆玉市冰点脱毛多少钱乌鲁木齐县去除红色胎记费用吐鲁番保妥适多少钱 When economists think about climate change, some think a lot about horse manure. Specifically, they consider the greatmanure crisis of the late 1800s, when the world’s cities relied on horses for transport to such an extent that a public sanitation disaster loomed. Fine minds set to work on a crisis that The Times of London estimated in 1894 was so dire that in 50 years every street in the city would be buried 9ft deep in horse droppings.当经济学家思考气候变化问题时,其中一些人会重点研究马粪。具体来说,他们研究的是19世纪末的马粪大危机。当时世界各地的城市极度依赖马匹作为交通工具,以至于一场公共卫生灾难迅速逼近。1894年,伦敦《泰晤士报》(The Times)估计,50年后这场危机会变得非常可怕,伦敦的每一条街道都将覆盖9英尺厚的马粪,于是一群聪明人开始着手应对这场危机。As it turned out, a simple solution was at hand: not new laws or policies but the motor car, a technical innovation so successful that the equine pollution problem was swiftly overcome.结果,很快就出现了一个简单的解决方法:不是新的法律或者政策,而是汽车。这种非常成功的技术革新让人们迅速解决了马粪带来的污染问题。The lesson is obvious for anyone worried about climate change, say economists such as Steven Levitt. In 2009’s SuperFreakonomics he and co-author Stephen Dubner used the tale to argue that technological fixes are often far simpler and cheaper than doomsayers imagine; and global warming could be addressed by so-called geoengineering, or manipulating the environment to halt rising temperatures.史蒂文#8226;莱维特(Steven Levitt)等经济学家表示,这给任何担忧气候变化的人提供了显而易见的教训。在2009年出版的《超级魔鬼经济学》(SuperFreakonomics)一书中,莱维特和合著者斯蒂芬#8226;杜布纳(Stephen Dubner)利用这个故事辩称,通过技术解决问题往往比末日论者想象的简单得多,成本也低得多;可以用所谓的地球工程来解决全球变暖问题,也就是通过操控环境来遏止温度上升。The dangerous allure of such thinking is a central theme tackled by two other economists: Gernot Wagner, an academic who works for the US Environmental Defense Fund, and Harvard professor Martin Weitzman in Climate Shock: The Economic Consequences of a Hotter Planet.另外两位经济学家认为此类想法具有危险的诱惑力,并作为其著作的主题加以讨论:就职于美国环保协会(Environmental Defense Fund)的学者赫尔诺特#8226;瓦格纳(Gernot Wagner)和哈佛大学(Harvard)教授马丁#8226;威茨曼(Martin Weitzman)合著了《气候冲击:一个变暖星球的经济影响》(Climate Shock: The Economic Consequences of a Hotter Planet)。They are right to do so. Interest in geoengineering ismounting as warming carbon dioxide emissions have continued to rise despite decades of UN climate negotiations, billions of dollars worth of renewable energy subsidies and sporadic attempts to price carbon. The failure of those efforts underlines the fact that climate change is, as the authors point out, the ultimate “free rider” problem. It is hard to get people to limit their own pollution when they bear the costs and the benefits are global.他们这样做是正确的。人们对地球工程的兴趣逐步增长,同时尽管联合国(UN)几十年来一直举行气候谈判,人们投入了数十亿美元为可再生能源提供补贴,偶尔还会尝试碳定价,但造成气候变暖的二氧化碳排放仍在继续上升。这些努力的失败凸显出如下事实:正如两位作者指出的那样,气候变化问题最终是“搭便车”问题。当人们自己承担成本、好处却是全世界共享的时候,他们就很难限制自身造成的污染。Geoengineering, on the other hand, is so cheap that one country alone could conceivably carry out a plan discussed by Levitt and many others: mimic the 1991 eruption of the Mt Pinatubo volcano in the Philippines, which cooled global temperatures by about 0.5C the following year, by shooting sulphur dioxide into the stratosphere to create a giant sunshade.另一方面,地球工程的成本非常低廉,可以说单个国家就能实施莱维特和其他许多人讨论过的一种方案:模拟1991年菲律宾皮纳图(Pinatubo)火山的喷发。那次火山喷发向平流层喷射了大量二氧化硫,制造了一个巨大的遮阳罩,使全球气温在接下来的一年里大约降低了0.5摄氏度。The cost could be lower than that of cutting emissions, say Wagner and Weitzman, while the impact could be huge — which, they argue, means geoengineering turns the standard economics idea of climate change on its head, from a “free rider” to “free driver” problem.瓦格纳和威茨曼表示,地球工程的成本的确可能比减排低,而影响却是巨大的——他们认为,地球工程彻底颠覆了经济学上对气候变化的标准看法,从“搭便车”问题变成了“随便开”问题。But the risks of such geoengineering are myriad — from ozone depletion to fast-rising temperatures should Mt Pinatubo-style techniques ever stop — because the underlying emissions causing warming would continue.但这种地球工程存在诸多风险,从臭氧层破坏到一旦停止皮纳图式的做法就会导致气温快速上升,因为引发气候变暖的潜在排放仍将持续。A further obstacle to reducing emissions is the lack of certainty about precisely how much warming they will cause. This is another theme of Climate Shock, a title chosen to highlight one widely misunderstood aspect of climate change: it is not enough merely to stabilise annual emissions. They have to be slashed to near zero to bring down C02 concentrations, which in 2013 rose to 400 parts per million, well above the 280 ppm of pre-industrial times.减排的另一个障碍是,对碳排放引发气候变暖的程度缺乏明确认知。这是《气候冲击》一书论述的另一个主题。作者之所以选择这个标题,是为了强调一个被广泛误解的气候变化问题:仅仅稳定年度排放量还不够。要降低碳浓度,碳排放量必须被大幅削减至接近零排放的程度。2013年碳浓度已经升至400ppm,远高于工业时代前280ppm的水平。Dissecting the latest scientific findings about how much global temperatures are likely to rise as C02 in the atmosphere doubles, the authors conclude there is about a 10 per cent chance of temperatures eventually exceeding a catastrophic 6C. Homeowners take out insurance policies against devastating fires that are almost always less likely than this.如果大气中的二氧化碳含量翻倍,全球气温可能会上升多少?两位作者仔细分析了最新的科学发现。他们的结论是,现在气温升幅大约有10%的几率最终会超过6度,而气温上升6度就会引发巨大灾难。房主会投保预防毁灭性大火,而实际上出现这种大火的几率几乎总是低于10%。The correct economic solution has been well understood for years, they argue: stop subsidising fossil fuels by about a ton of C02 globally, and create a price of at least a ton. But Climate Shock advises economists to stop demanding a global carbon price and start working on more politically possible solutions, such as fuel economy standards. That sounds dull compared with geoengineering. But it is also infinitely safer.多年来,人们已对经济方面的正确对策了如指掌,他们主张停止在全球征收每吨约15美元的碳税(那样是在补贴化石燃料),碳价至少应提高至每吨40美元以上。但是《气候冲击》一书则建议经济学家不要再制定全球碳价,开始探寻更偏政治的可能解决方案,比如制定燃油经济标准。与地球工程相比,这样的举措听起来有些枯燥,但它也安全得多。This is not a book for people deeply versed in climate policy, few of whom will find its contents remotely shocking. For the intelligent lay er wanting a lively, lucid assessment of the economic consequences of global warming, however, it is well worth ing.这本书不是为那些深谙气候政策的人准备的,他们不会觉得这本书的内容多么令人震惊。这本书对全球气候变暖的经济影响进行了生动而清晰的评估,对于那些想要一览此类内容的聪颖的一般读者,该书非常值得一读。The writer is the FT’s environment correspondent本文作者是英国《金融时报》环境记者Climate Shock: The Economic Consequences of a Hotter Planet, By Gernot Wagner and Martin Weitzman, (#163;19.95, .95)《气候冲击:一个变暖星球的经济影响》(Climate Shock: The Economic Consequences of a Hotter Planet),赫尔诺特#8226;瓦格纳与马丁#8226;威茨曼合著,售价19.95英镑/27.95美元 /201504/368832乌鲁木齐米东区做文眉手术多少钱

昆玉市小腿减肥多少钱哈密鼻翼整形多少钱 When you#39;re a famous CEO, you end up giving so many interviews that you might forget what you#39;ve said in them all.You might also give interviews on particular days when you#39;re in particular moods. This can lead to particular articles being published that you particularly regret.如果你是一位著名CEO,在接受了无数采访之后,你可能都不记得你说过什么了。可能某天你在接受采访时心情不佳,采访后刊登出来的文章会让你对自己所言十分后悔。So it is, perhaps, with an interview in which Tesla CEO Elon Musk gave to Germany#39;s Handelsblatt. In it, he suggested -- jokingly?-- that the Cupertino, California, tech titan hires Tesla#39;s engineering castoffs.德国商报采访特斯拉CEO埃隆·马斯克就是这种情况。在采访中,或许是半开玩笑,马斯克说技术行业的大亨——位于加利福尼亚州的库皮蒂诺市所雇佣的是特斯拉之前解雇的工程师。;Did you ever take a look at the Apple Watch? No, seriously,; he said of Apple#39;s alleged foray into cars. ;It#39;s good that Apple is moving and investing in this direction. But cars are very complex compared to phones or smartwatches.;;你之前看过苹果手表吗?没有;。马斯克在谈到苹果公司有意进军汽车行业时说道:;苹果公司转向这个行业是件好事。但是同手机和智能手表相比,汽车可比那些东西复杂多了。;Some wondered whether Apple and Tesla had endured a falling out. It had once been rumored that the two companies might come together.有些人担心苹果和特斯拉是否会因此产生嫌隙。之前曾传闻两家公司或将合并。Thankfully, Musk took to Twitter on Friday to dismiss the very notion that he and Apple weren#39;t BFFs.好在周五时,马斯克发推特,否认自己与苹果公司关系不佳的谣言。;Yo, I don#39;t hate Apple, he first tweeted. ;It#39;s a great company with a lot of talented people. I love their products and I#39;m glad they#39;re doing an EV.;;嘿!我可没说自己讨厌苹果,;他在推特中称:;苹果公司有许多才华横溢的人。我喜欢他们的产品,我很高兴他们准备生产电动汽车。;Those of punctilious mien might suggest that Apple#39;s ;talented people; still just weren#39;t talented enough to work for Tesla. They might also muse that Musk seems to know definitively that Apple is making an electronic vehicle. Might that be because the alleged castoffs from Tesla who now work at Apple have told him?这些精心设计过的推文也许是在说这些;才华横溢;的员工仍然没有资格为特斯拉效力,或者马斯克已经确定苹果公司在研究电动汽车。这难道是那些被特斯拉解雇的员工跑回来告的密?Musk followed up with another tweet addressing his views on the Watch. ;Regarding the watch, Jony amp; his team created a beautiful design, but the functionality isn#39;t compelling yet. By version 3, it will be.;马斯克随即又发了第二条推特,提出自己对苹果手表的看法。;对于手表,乔尼和他的团队所设计出来的产品十分漂亮,但是功能尚且不够完善。也许到第三代会很不错。;Translation: Version 2 will still be an inadequate lump of beautiful design.话外音:第二代仍然是个功能残次的绣抱枕头。Commenters on Musk#39;s tweets weren#39;t all amused. Someone called Joe Zou suggested that Tesla#39;s CEO was merely jealous that the Apple Watch made more profit in three months than Tesla will in 2015.马斯特的推特的并不都十分不搞笑。一位叫乔伊·周的网友认为特斯拉的CEO纯粹就是在嫉妒苹果手表三个月内的盈利比特斯拉2015年的年盈利还要多。 /201510/403208乌市第一人民医院激光去痘手术多少钱

哈密市激光去除雀斑费用Wu Wenjun and Wu#39;s Method吴文俊及“吴方法”wu Wenjun, a well known mathematician, born in Shanghai in May 1919, graduated from Shanghai Jiaotong University in 1940. In 1947,he went to France for advanced study in University of Strassbourg. In 1949, he obtained his national doctor s degree of France.In 1957, he was elected as an academician of Chinese Academy of Sciences ( CAS). In 1990, he was elected as an academician of the Third World Academy of Sciences.吴文俊,1919年5月12日出生于中国上海,著名的数学家,1940年毕业于上海交通大学,1949年获得法国斯特拉斯堡大学士学位。1957年,他被选举为中国科学院( CAS)的院士。1990年,被选举为第三世界科学院科学院士。His research work covered a wide area of mathematics.lts main achievements involved two areas of topology and mathematical mechanization. In the late 1970s, against the background of great development of computer technology, he has inherited and developed the tradition of ancient Chinese mathematics (that is, algorithm of thinking), and turned to study automated theorem proving, completely changed the face of this area. As a disciplinary precursor, Wu made monumental contributions to the field of topology by introducing Wu#39;s imbedding and characteristic classes and establishing Wu#39;s Formulae, well-known for Wu#39;s Method, which have been widely accepted by his counterparts and had exerted worldwide influence. Wu#39;s research has made a series of international leading results and has been applied internationally popular symbolic computation software.吴文俊的研究工作涉及数学的诸多领域,其主要成就表现在拓扑学和数学机械化两个领域。他为拓扑学做了奠基性的工作。20世纪70年代后期,在计算机技术大发展的背景下,他继承和发展了中国古代数学的传统(即算法化思想),转而研究几何定理的机器明,彻底改变了这个领域的面貌,是国际自动推理界先驱性的工作。他的示性类和示嵌类研究被国际数学界称为“吴公式”,“吴示性类”,“吴示嵌类”,并在国际上产生了深远影响,被称为“吴方法”。吴的研究取得了一系列国际领先成果并已应用于国际上当前流行的符号计算软件方面。 /201602/419404 BRUSSELS — The European Union’s antitrust chief on Wednesday formally accused Google of abusing its dominance in web searches to the detriment of competitors and began official proceedings into whether its Android smartphone software forces phone makers to favor the company’s own services and applications.布鲁塞尔——欧盟反垄断最高官员周三正式指控谷歌(Google)利用其在网络搜索方面的主导地位,损害竞争对手,并将就Android智能手机软件是否强制手机制造商偏袒谷歌自身务和应用的做法提起诉讼。“If the investigation confirmed our concerns, Google would have to face the legal consequences and change the way it does business in Europe,” said Margrethe Vestager, the European Union competition commissioner.“如果调查结果实了我们的忧虑,谷歌将不得不面临法律后果,并且改变它在欧洲的商业模式,”欧盟竞争事务专员玛格丽特·韦斯塔格尔(Margrethe Vestager)说。The abuse charge focused on accusations that Google diverts traffic from its rivals to favor its own products and services, particularly websites for shopping. That led the European Commission to issue a set of formal charges, known as a statement of objections.指控主要集中在指责谷歌从竞争对手分流流量,偏向其自身产品和务,尤其是购物网站。这导致欧盟委员会发布了一套被称为异议声明的正式指控。A large number of online operators have complained about Google in other areas, like travel and mapping. Ms. Vestager said that the inquiry might eventually expand beyond shopping sites.许多在线运营商已经抱怨过谷歌在旅游和地图等其他领域的做法。韦斯塔格尔说调查或将最终扩展到购物网站以外的领域。The commission also said it was stepping up a separate investigation into whether phone makers that agree to use Android — and that also want Google applications like YouTube — face contractual requirements to place those applications and other Google-branded applications in prominent positions on a mobile device.委员会还称,其正在加强一项独立调查,针对同意使用Android系统并希望使用YouTube等谷歌应用的手机制造商,调查是否存在合同要求它们在移动设备的显著位置放置谷歌品牌应用。 /201504/370539新疆空军乌鲁木齐医院修眉多少钱铁门关去疤痕多少钱
