大理无痛人流安全吗大理好点的妇科医院大理市鹤庆县做人流哪家医院最好的 A FREIGHT train, its dozen cars loaded with coal covered in a light dusting of snow, snaked through the narrow valley, sometimes following the two-lane highway and sometimes crossing it. The valley was silent and snowy, and though it was two days into 2012 it could easily have been 1982, 1942 or 1922: coal has been mined in Appalachia and carried out by rail for well over a century.一列货运火车装载着十二车煤炭,煤炭上覆盖着一层薄薄的白雪,火车迂回地行进于狭窄的山谷之间,时而沿着这一条双车道高速公路行驶,时而又穿过那一条。峡谷寂静而多雪,尽管这已经是进入2012年以来的的第二天了,然而在阿帕拉契亚,这样的一天也可以发生在1982年,1942年或者是1922年:一个世纪以来,煤炭在这里挖掘,并不断用火车运走。And by some measures, coal is still going strong. It provides more of Americarsquo;s electricity than any other fuel. Production has fallen off since 2008, but it remains high, as do prices, for which thank the developing worldrsquo;s appetite. In Appalachia, coal remains a source of well-paid jobs in a region that needs them: for the first three quarters of 2011 employment in the Appalachian coal industry was at its highest level since 1997. And the Powder River Basin, which spans Wyoming and Montana, has become Americarsquo;s major source of coal in the past decade, relieving overmined Kentucky and West Virginia. The Energy Information Administration (EIA) reckons America has enough coal to meet current demand levels for the next 200 years.然而在某种程度上,煤炭业依旧很昌盛。较比其他的燃料,煤炭为美国提供了更多的电力资源。自2008年以来,煤炭产量逐渐减少,但仍能维持较高的生产量,而且价格也没有大幅跌落,这都得益于发展中国家对于煤炭的广泛需求。在阿帕拉契亚那些需要煤炭的地区,煤炭一直是高收入工作的主要来源:在2011年的前三个季度,煤炭产业的就业状况达到了其自1997年以来的最高水准。在过去十年里,横跨怀俄明州和蒙大纳的粉河盆地已经成为了美国重要的煤炭来源,缓解了肯塔基州和西弗吉尼亚州的重度开采。能源信息则认为,美国有足够的煤炭来满足其未来200年的需求。But if the raw numbers look good, the trends tell a different story. Regulatory uncertainty and the emergence of alternative fuel sources (natural gas and renewables) will probably make Americarsquo;s future far less coal-reliant than its past. In 2000 America got 52% of its electricity from coal; in 2010 that number was 45%. Robust as exports are, they account for less than one-tenth of American mined coal; exports cannot pick up the slack if Americarsquo;s taste for coal declines. Appalachian coal production peaked in the early 1990s; the EIA forecasts a decline for the next three years, followed by two decades of low-level stability. Increased employment and declining productivity suggest that Appalachian coal is getting harder to find. 但如果原始数据前景看好,那么未来趋势则另当别论。管理规章的不确定性和可替代燃料能源的出现可能会使美国不再会像过去一样依赖于煤炭资源。2000年美国52%的电力资源来自煤炭;2010年这一数字是45%。尽管出口很强劲,出口的煤炭量不到美国开采煤炭量的十分之一;然而如果美国自身对于煤炭的需求量逐渐减少,对外出口也不会缓解这一萧条景象。阿帕拉契亚的煤炭产量在20世纪90年代初达到顶峰; 美国能源信息预测未来三年煤产量会减少,之后会迎来二十年的低水平稳定期。就业增加,生产率降低,预示着阿帕拉契亚的煤炭会越来越难开采。Toughening regulation has an effect, too. Coal-fired power plants are the source of more than one-third of greenhouse-gas emissions in America. Last July the Environmental Protection Agency (EPA) issued a rule that requires 28 states to reduce the amount of sulphur dioxide and nitrogen oxide they emit; in December came another, reducing the amount of mercury and other toxic air pollutants that power plants can puff out. 加强管理也具有一定的效用。美国三分之一以上的温室气体排放来自燃煤发电厂。去年七月,环境保护局发表了一项规章,要求28个州减少二氧化硫和氮氧化物的排放;在接下来的十二月份,又要求发电厂减少汞和其他有毒空气污染物的排放。Many plants have aly made the necessary upgrades and retrofits; around 53% of Americarsquo;s coal-fired capacity comes from units fitted with scrubbers. But others, particularly older plants, will have to decide whether such expensive upgrades are worth doing at all. Most of Americarsquo;s coal-fired capacity comes from plants at least 30 years old, and as much as 14% of existing coal-fired plants, accounting for 4% of Americarsquo;s generation capacity, will have to be retired in the next five to eight years. Energy providers face a stark choice. They can fight these regulations in court (outcome uncertain). They can retrofit old plants: plenty have done that, too. Or they can build new plants;in which case, far more are choosing plants that burn natural gas or use renewables rather than coal.许多工厂已经做了必要的升级和改进;大约53%的美国燃煤生产力来自装有洗涤器的装置。但是其他的工厂,尤其是一些历史更久远的工厂,必须得决定这样昂贵的升级到底值不值。大多数的美国燃煤生产力来自于30年余久的工厂,这样的工厂占现有燃煤工厂的14%,发电量占美国发电总量的的4%,然而这些工厂在接下来的5到8年内必须淘汰。能量供应商面临着一个严峻的抉择。他们可以上诉公堂,与这些规章条例作斗争。他们也可以改进这些工厂:很多人也已经这么做了。或者他们可以建造新的工厂;; 在这种情况下,更多人会选择烧天然气或使用可再生能源,而不是煤炭。201202/169710大理州生孩子哪家好

They recall wistfully a golden age when flying was glamorous, not an ordeal of long lines and intrusive pat-downs.旅客常常抱怨飞行不再有趣。他们怅然回忆起飞行的黄金时期,那时坐飞机光照人,而不是长长的队伍和烦扰的搜身带来的痛苦。In America these are inflicted by the Transportation Security Administration (TSA), which was set up after the terrorist attacks on September 11th 2001. It is now one of the countrys most hated institutions. Many passengers scorn its pettifogging rules. Many complain of ineffectual ;security theatre ;. In an Economist online debate last month, a crushing 87% of respondents agreed that the changes to airport security since 2001 had ;done more harm than good;.在美国,这些痛苦都是由美国运输安全造成的,交通安全局是2001年9月11日的恐怖袭击后设立的,该机构现在是美国最讨人厌的机构之一。许多旅客嘲笑那些挑剔的规章制度,许多旅客抱怨安全措施毫无效果。上月在经济学人的网上辩论中,压倒性的87%的应答者同意2001年以来机场安检措施的改变;适得其反;。The man given the impossible task of opposing the motion was Kip Hawley, a former TSA boss. Even he ily admitted that airport security needed reforming. And on April 14th, writing in the Wall Street Journal, Mr Hawley offered some sensible proposals on how to do it.提出反对动议这一不可能任务的人是前美国运输安全局长基普?霍利。他也乐意承认机场安检需要改革。4月14日,霍利先生在华尔街日报的一篇文章中就此问题提出了一些有益的提议。One idea the airlines will not like is to stop them charging for checked bags. Mr Hawley says this would speed things up by discouraging flyers from dragging all their stuff through security. But carriers have come to rely on such fees, which rake in billions. IATA , their lobby group, argues that, in any case, checkpoint delays were aly lengthy in the mid-2000s, before most airlines charged bag fees.这些提议中,航空公司可能不会喜欢的是停止对受检行李收费。霍利先生表示这会阻止旅客拖着所有行李通过安检,从而提高效率。但是航空公司依靠这笔数以十亿计的费用。游说集团国际航空运输协会争辩说,2000年中期在大多数航空公司对行李收费之前,安检点已经拖延很厉害了。Mr Hawley would also allow all liquids on flights, though those choosing to carry them might have to join a queue to have them scanned (something the European Union intends to start doing next year). He would also lift the bans on such things as knives and lighters. Stronger cockpit doors have made it much harder to use weapons to bring down a flight. And tests run by the TSA found that officers were so busy hunting for lighters and other fairly trivial banned items that they overlooked dummy bomb parts placed nearby.霍利先生同样会允许飞行时携带所有液体,但是这些旅客可能需要排队检测。(欧盟打算明年开始这一举措。)他同样会取消对刀具和打火机等物品的禁令。更厚实的机舱门使得利用武器挟持飞机更为艰难。运输安全的测试发现安检人员忙于寻找打火机以及其他琐碎的违禁品而忽略放置在附近的仿真炸弹部件。In general, says Mr Hawley, predictable and rigid checks help terrorists: they design plots around them. So instead of subjecting everyone to the same checks, security should be randomised. However, he does not back one reform that the airlines are keen on: a ;trusted traveller; scheme in which flyers who have been vetted are spared most checks. Mr Hawley, who once liked the idea, now worries that terror groups are recruiting ;clean; agents who would pass such vetting.霍利先生表,总的来说,例行的严格安检有利于恐怖分子,他们围绕这些措施做文章。所以安检措施应该随机化,而不是让每个人接受同样的安检措施。但是他并不持航空公司很热心的一项改革措施:;旅客白名单;计划,受过审查的旅客会免除大多数安检。霍利曾经喜欢这一想法,现在却担心恐怖组织会招募那些通过审查的;清白;恐怖分子。IATA thinks that if vetting were thorough, and a few trusted travellers were checked at random, this problem could be overcome. The airlines also propose merging check-in, security, passport control and customs inspection into a seamless ;checkpoint of the future;. But getting government agencies to agree to such a move will be like asking hyenas to share a steak .国际航空运输协会则认为如果审查够彻底,而且一些受信任的旅客随机安检,这个问题可以克。航空公司同样提议整合登记签到,安检,护照管理和海关检查成为无缝衔接的未来安检点。但是说政府部门统同意这一举措将会像要求鬣分享牛排一样不可能。Even if all these reforms were introduced, far more would have to be done to make flying fun once more. Airlines would need to bring back wide seats and generous meals and drinks. Tedious safety drills and strict seat-belt rules would have to go, as would rowdy stag parties and wailing children. One can but dream.即使实行所有的这些改革措施,使飞行重新变得有趣还需要做很多工作。航空公司需要恢复宽大的座位,提供免费的食物饮料。令人生厌的安全演习和严格的安全带规则统统废除,闹哄哄的男性聚会和嚎啕大哭的孩子都不复存在。我们只能在梦中见到了。 /201210/203627大理附属医院网上预约挂号

Gordon Fullerton saw something remarkable. Above the tail of the shuttle, where there should have been empty space, they saw a faint orange glow instead, flickering with ghostly light. Was the space shuttle haunted? What was going on?时光倒转回1982年,在宇航员杰克·洛思马和查尔斯·戈尔登·福勒顿进行第三次航天飞行时,他们看到了惊奇的一幕。在飞机尾部原应是空白的地方,出现了微弱的橙色辉光,诡异地扑闪着。难道航天飞机上也闹鬼?这到底是怎么回事?To understand this phenomenon, known as ;shuttle glow,; you should know something about the region of space where the shuttle orbits. NASA shuttles stay in low Earth orbit, which is generally about a hundred and seventy miles above the Earths surface. At that height, the atmosphere has tapered away to almost nothing--less than a billionth of the pressure it is at ground level--but there are still gasses there. Indeed, low Earth orbit is well within the ionosphere, a major part of our atmosphere.为了弄清楚“航天飞机辉光”这一现象,有一点你应该注意到,那就是航天飞机飞行轨道所在的区域。美航局的飞机飞行时,一般保持在近地轨道上,即距离地表一百七十英里的地方。在这样的高度,大气程锥形逐渐减少——大气压力比地表的十亿分之一还小——但这里仍然有空气存在。实际上,近地轨道基本被电离层覆盖。而电离层是大气的重要组成部分。The thin gasses of the ionosphere rush past the space shuttle at about five miles per second, forming a very fast, very thin wind. This wind is so thin youd never be able to feel it, even if you stuck your head out the space shuttle window the way a dog sticks its head out a moving car. The wind causes two things to happen.飞机以每秒5英里的速度驶过之后,电离层稀薄的空气就会形成一股快速流动的细风。人类无法感觉到这种细风,即使你将头伸到飞机窗外(像一样将头伸出飞速行驶的汽车)也感觉不到。这种细风会引起两件事情。First, it erodes the surfaces of some materials.The erosion is slight, but it can be significant for camera lenses or other sensitive equipment. Second, the shuttles surface can scoop up atoms from this wind, and these atoms can undergo chemical reactions. One reaction, involving nitrogen and oxygen, can produce a luminous orange glow. And thats what the astronauts saw. It wasnt a ghost--it was shuttle glow.第一,它会侵蚀一些材料的表面。这种轻微的侵蚀用照相机或者其它敏感的设备看很明显。第二,航天飞机的表面会从细风中捕获原子,并且这些原子能发生化学反应。有一种氮和氧的反应就能产生明亮的橙色辉光。这就是宇航员所看到的光。它不是鬼火,而是辉光。原文译文属!201209/200518大理市附件炎治疗方法大理治疗妇科哪最好
