广安冷光美白喷砂洁牙去哪里医院好成都种植牙补牙多少钱英美文化浓厚的几处景致1. Wall Street (华尔街) 纽约曼哈顿岛南部的一条街。全长不过三分之一英里,街道狭窄而短,从百老汇到东河仅有7个街段。1792年荷兰殖民者为抵御英军侵犯而建筑一堵土墙,从东河(th e East River)一直筑到哈德逊河(the Hudson River),后沿墙形成了一条街,因而得名Wall Street。后拆除了围墙,但“华尔街”的名字却保留了下来。然而,它却以“美国的金融中心”闻名于世。美国根( Morgan)财阀、洛克菲勒(Rockefeller)石油大王和杜邦(E.I.du Pont de Nemours and Company)财团等开设的、保险、航运、铁路等公司的经理处集中在这里。著名的纽约券交易所(Stock Exchange)也在这里。 2. Fleet Street (舰队街) 原为伦敦城外的一条小河。16世纪时,河的两岸住满了人家,但河水浑浊,臭气熏天。1737年开始了舰队河的掩埋工程。填平后,原址成为一条街,取名amp; ;舰队街”。18世纪以来,英国的老报社、出版社都设立在这条街上。影响较大的有《每日电讯报》(The Daily Telegraph)、《每日邮报》(Daily Mail)。“舰队街”已经成为英国报业及新闻界的代名词。 3. Tower of London (伦敦塔) 位于泰晤士河北岸的塔山(Tower Hill)上,是一个占地达18英亩,由城堡、炮台和箭楼等组成的庞大建筑群,建于l078年,当时是外族征者威廉(William the Conqueror)建造的一个军事城堡,中心塔是高约27米的白塔(White Tower),周围有13座塔。12世纪起,历代国王在这里修建王宫、教堂。其中的血塔(the Bloody Tower)被国王用来专门囚禁政治要犯及国王的死敌,是一座死牢。被关进这座塔里的人大多被处死。伦敦塔充当了国家监狱。如今,伦敦塔已经成为收藏文物珍宝的物馆, 保存有古代武器、历代王冠和王室珠宝,还有一根镶有大宝石的皇杖。此外,伦敦塔的东侧附近还有一座塔桥(Tower Bridge),是一座吊桥。 4. Poets' Corner (诗人角) 英国威斯敏斯特教堂内著名文学家的坟墓。这里墓冢累累,墓碑林立。此处埋葬着许多著名的英国文学家。英国诗歌之父乔叟在此不仅有墓穴,还有一个纪念窗。19世纪著 名的小说家狄更斯(Charles Dickens,1812-1870)被安葬在诗人角的中央。陪伴他长眠的还有19世纪诗人丁尼生(Alfred Tennyson,1809-1892)、布朗宁(Robert Browning,1812-1889)、小说家哈代(Thomas Hardy,1840-1928)及英文词典编纂之父约翰逊(Samuel Johnson,1709-1784)。莎土比亚的坟墓虽然在他的故乡,但这里也有一个壁龛放着他的雕像。但英国文学史上两位了不起的浪漫主义诗人拜伦(Geo rge Gordon Byron,1788-1824)和雪莱(Percy Bysshe Shelley,1792-1822)因被认为有异端思想而被排斥在“诗人角”之外。5. Shangri-La (香格里拉) 原为英国小说家希尔顿(James Hilton,1900-1954)在他的小说《失去的地平线》(Lost Horizon,1933)中描述的一个在飞机失事后紧急降落在中国西藏的一个虚构地名。由于小说及后来拍成的电影的广泛影响,香格里拉遂成为公认的世外桃源或隐秘之地 。第二次世界大战期间,美国空军首次轰炸东京时,美国总统罗斯福(Franklin D. Roosevelt,1882-1945)曾对外界说,这些飞机是从香格里拉起飞的。罗斯福还将美国总统设在弗吉尼亚州的一个山间别墅命名为香格里拉。后来,艾 森豪威尔将之改为戴维营,以纪念他的孙子戴维。 6. Greenwich Village (格林尼治村) 位于美国纽约市曼哈顿区。英国殖民统治期间为一村庄。1910年以后,不信奉英国国教的作家、艺术家、文人墨客、大学生等知识分子开始汇聚此地。20世纪80年代 ,这里建起了高级公寓,很多地段成为时街区。村内街道弯曲,建有老式房子、外国餐馆、古玩店、实验剧场、标新立异的夜总会。纽约大学也建在村中。7. Hyde Park (海德公园) 英国最大的皇家公园。位于伦敦市中心的威斯敏斯特教堂 (Westminster Abbey,即西敏寺)地区,占地360多英亩,原属威斯敏斯特教堂产业。16世纪,英王亨利八世将之用作王室的公园。查理一世执政期间,海德公园曾向公众开放。185 1年,维多利亚女王首次在这里举办伦敦国际览会。这里现在也是人们举行各种政治集会和其他群众活动的场所,有著名的“演讲者之角”(Speak ers' Corner)。 8. Dead Valley (死谷) 美国加利福尼亚东部的沙漠地区有一条由西北向东南延伸的断层地沟,长约225公里,宽6-26公里。部分地沟低于海平面,是西半球最低的陆地。1873年 ,在这里发现硼砂矿。19世纪80年代以后,又在附近发现铜、银、铝等矿藏。后来大量采矿。矿源枯竭后,人们迁走,留下一片荒凉瓦砾。1849年曾有一队寻矿的人进入沙漠 底谷,几乎葬身其中,后脱险,因而起名“死谷”。1933年,这里辟为死谷国家公园。 转自我爱英语网 /200803/32131自贡市第四人民医院拔牙智牙口臭口腔溃疡多少钱 胖妈妈哺乳期较短Overweight and obese women are less likely than normal-weight women to keepbreastfeedingtheir infants for six months or longer, a study from Australia shows. Dr. Wendy Hazel Oddy of the Telethon Institute for Child Health Research in Perth and colleagues looked at 1,803 children and their mothers participating in a large pregnancy study. Eighteen percent of the women were overweight or obese before becoming pregnant.After the researchers adjusted for factors including socioeconomic status and years of education, they found that women who were overweight or obese were less apt to attempt breastfeeding at all and those that did were less likely to continue breastfeeding.Obese women were about twice as likely to have breastfed for less than two months or less than four months, while overweight women were 52 percent more likely than normal weight women to have stopped breastfeeding before two months, and 62 percent more likely to have stopped before four months.Overall, the researchers found, overweight or obese women were 76 percent more likely to stop breastfeeding before their infants were six months old than their normal weight peers.A number of factors could help explain the findings, the investigators say. For example, excess weight may change a woman's hormonal profile, making sustainedlactationmore difficult, or it may be harder for an infant to "latch on" to breast tissue if the mother is overweight or obese.The researchers also report that overweight and obese women were more likely to have pregnancy complications andC-sectionsthan normal-weight women.据澳大利亚的一个研究表明,与正常体重的女性相比,体重超标和肥胖的女性对她们的孩子进行六个月或更长时间母乳喂养的概率较小。在一项大规模的妊娠期调查中,佩斯Telethon儿童健康研究所的温迪·黑泽尔·奥迪医生和他的同事对1803对母亲和孩子进行了研究调查。其中有18%的妇女在怀之前就偏胖甚至肥胖。 综合社会经济地位和受教育年限等因素的影响,研究人员发现体重超标或肥胖的女性进行母乳喂养的可能性相对较小,而且其中正进行母乳喂养的女性继续下去的可能性也较小。调查发现,肥胖女性在孩子不满两个月或四个月就停止母乳喂养的概率是正常体重女性的两倍左右,超重女性在孩子满两个月前停止母乳喂养的概率要比正常体重女性高52%,四个月前停止母乳喂养的概率高62%。研究人员发现,总体来看,超重或肥胖的女性在孩子满六个月前停止母乳喂养的概率要比正常体重女性大76%。研究人员说,这些发现可用很多因素来解释。比如,体重超标可能会改变女性的激素水平,从而使哺乳期长度受到影响;或者是,婴儿吮吸超重或肥胖妈妈的乳房可能有些困难。此外,研究人员称,体重超标和肥胖女性患妊娠期并发症及剖腹产的几率要比正常体重的女性大。Vocabulary:breastfeed: 母乳喂养lactation: 哺乳期C-sections: 剖腹产 /200803/31406打呵欠有助于醒脑Latest research shows that yawning helps in keeping the brain cool, contradicting the popular belief that yawning promotes sleep and is a sign of tiredness.Yawning involves opening the mouth involuntarily while taking a long, deep breath of air. It is commonly believed that people yawn as a result of drowsiness or weariness because they need oxygen.However, researchers at the University of Albany in New York said their experiments on 44 students showed that drawing in air helps cool the brain and helps it work more effectively.They said that their experiments showed that raising or lowering oxygen and carbon dioxide levels in the blood did not produce that reaction.Study participants were shown s of people laughing, being neutral and yawning, and researchers counted how many times the volunteers responded to their own 'contagious yawns,' reported the online edition of B News.The researchers found that those who breathed through the nose rather than the mouth were less likely to yawn when watching a of other people yawning. This was because vessels in the nasal cavity sent cool blood to the brain.The same effect was found among those who held a cool pack to their forehead, whereas those who held a warm or room-temperature pack yawned while watching the .'Since yawning occurs when brain temperature rises, sending cool blood to the brain serves to maintain optimal levels of mental efficiency,' the authors wrote in the journal Evolutionary Psycology. 最新研究表明,打呵欠有助于保持头脑清醒,这与“打呵欠促使人进入睡眠状态以及是疲倦的一种表现”的普遍看法正好相反。打呵欠使人在不由自主张开嘴的同时,能长长的、深深的吸一口气。普遍看法认为,人们打呵欠是由于困乏或疲倦造成的,因为他们需要氧气。然而,据纽约奥尔巴尼大学的研究人员介绍,他们对44名学生的实验表明,吸入空气有助于醒脑,从而使它更为有效的工作。研究人员称,实验表明,提高或降低血液中氧气和二氧化碳的含量不会导致那种反应。据B新闻网报道,研究人员先让实验对象观看人们大笑、正常状态以及打呵欠的视频,然后计算出志愿者“传染性打呵欠”的次数。研究人员发现,在看别人打呵欠的视频时,用鼻子呼吸的人比用口腔呼吸的人打呵欠的几率要小。这是因为鼻腔里的血管将温度较低的血液送到了脑部。将冰袋敷在前额上也能起到类似的效果,而在观看视频时用暖水袋或室温水袋敷在额头上的人却无法避免打呵欠。这份在《进化生理学》上发表的研究报告提到,“由于脑部温度上升时就会打呵欠,所以将低温血液送至大脑能够保持脑部效率的最佳水平。” /200803/32264成都全口种植牙大概费用

达州市中西医结合医院洗牙洁牙窝沟封闭蛀牙龋齿怎么样好吗你浪费了多少上班时间?Americans who feel bored and underpaid do work hard -- at surfing the Internet and catching up on gossip, according to a survey that found U.S. workers waste about 20 percent of their working day.An online survey of 2,057 employees by online compensation company Salary.com found about six in every 10 workers admit to wasting time at work with the average employee wasting 1.7 hours of a typical 8.5 hour working day.Personal Internet use topped the list as the leading time-wasting activity according to 34 percent of respondents, with 20.3 percent then listing socializing with co-workers and 17 percent conducting personal business as taking up time.The reasons why people wasted time were varied with nearly 18 percent of respondents questioned by e-mail in June and July said boredom and not having enough to do was the main reason.The second most popular reason for wasting time was having too long hours (13.9 percent), being underpaid (11.8 percent), and a lack of challenging work (11.1 percent).While the amount of time wasted at work seems high, Bill Coleman, chief compensation officer at Salary.com. said the numbers have improved, with the amount of time wasted dropping 19 percent since Salary.com conducted its first annual survey on slacking at work in 2005. Then workers reported wasting 2.09 hours of their working day."I think (the decline) is really a result of the economy and that there's more business, more work available and less time tosit around wondering what you are going to do with your day," Coleman told reporters. 厌倦工作、又觉得薪金太低的美国人把时间都浪费到了上网和闲聊上。一项调查发现,美国人浪费了约20%的上班时间。该项由在线薪酬公司Salary.com网站开展的在线调查共有2057名雇员参与。调查发现,每10名员工中约有6人承认自己在上班时浪费了时间。在一个典型的8.5小时工作日中,一般员工会浪费1.7个小时。上网是第一大浪费上班时间的活动,有34%的受访者利用上班时间上网;20.3%的受访者在上班时与同事闲聊;17%的人处理私人事务。人们在上班时做其它事情的原因各不相同。在6月和7月的电子邮件受访者中,近18%的人称这样做的主要原因是无聊和没事可做。第二大原因是工作时间太长(13.9%);其次是薪资太低(11.8%)和工作缺乏挑战(11.1%)。尽管看起来被浪费的上班时间很多,但Salary.com网站的薪资主管比尔·柯尔曼说,从具体数字 上看,情况还是有所改观。自从2005年Salary.com网站首次开展此项一年一度的调查以来,被浪费的上班时间数下降了19%。当时员工一个工作日 浪费的时间为2.09小时。科尔曼在接受记者采访时说:“我认为这是经济发展的结果。公司业务更多、需要处理的事情更多,员工们已没有多余的时间去考虑如何打发时间了。” /200803/29231郫县妇幼保健院瓷嵌体的费用 US technology executives seeking to ingratiate themselves with China’s leadership are known for making big entrances, and Tim Cook set the bar high yesterday after he arrived in Beijing to fanfare over Apple’s bn investment in the Didi Chuxing ridehailing app.很多人知道,寻求讨好中国领导层的美国科技业高管会高规格地访问中国。蒂姆#8226;库克(Tim Cook)昨日在这方面进一步抬高了标杆,他到达北京,大张旗鼓地为苹果10亿美元投资打车软件滴滴出行(Didi Chuxing)造势。He took a Didi car to his first destination, an Apple store in Beijing’s Wang-fujing shopping district, accompanied by Jean Liu, the Chinese company’s president.在滴滴总裁柳青(Jean Liu)的陪同下,他乘坐一辆滴滴汽车前往第一个目的地,位于北京王府井购物区的一家苹果商店。“We are very proud of that investment,” Mr Cook told journalists as he posed with a host of local internet entrepreneurs.“我们很自豪做出了这笔投资,”库克一边与许多中国互联网企业家合影,一边告诉记者。“Didi has 14m drivers, 300m users — actually 300m and one now, because Jean and I took a Didi ride here this morning,” he said.“滴滴拥有1400万司机和3亿用户——现在实际上有3亿加1个用户,因为柳青和我今早是乘坐滴滴车辆来到这里的,”他说。Beijing is a favoured destination for US tech chiefs whose companies are in dispute with China’s leadership. And high-profile shows of goodwill tend to be made in as public a way as possible.对于那些与中国领导层存在纠纷的美国科技公司,北京是它们的掌舵人喜欢访问之处。他们往往会尽可能公开地高调示好。In March Mark Zuckerberg, the founder of Facebook — which remains blocked to China’s 700m internet users — was derided online as a “Zuck-up” when he jogged through Tiananmen Square in a haze of choking pollution.今年3月,Facebook的创始人马克#8226;扎克伯格(Mark Zuckerberg)——中国的7亿互联网用户仍无法访问Facebook网站——在雾霾污染中跑步经过天安门广场,由此在网上被嘲笑为“Zuck-up”。He also had a meeting with Liu Yunshan, the country’s propaganda chief.他还会晤了中国最高宣传官员刘云山。After Microsoft’s offices were raided by Chinese government investigators as part of a tax probe, a visit by Satya Nadella followed, after little more than the standard visa waiting period, in September 2014.2014年9月,作为税务调查的一部分,微软(Microsoft)办公室遭到中国调查人员的突击检查。在标准的签等待期过后,微软首席执行官萨蒂亚#8226;纳德拉(Satya Nadella)便访问了北京。Senior executives of Qualcomm have made Beijing a regular destination since the US semiconductor company was targeted in a 2014 antitrust investigation that resulted in a bn fine the following year.自从高通(Qualcomm)在2014年的反垄断调查中成为目标以来,这家美国半导体公司的高管频频访问北京。次年高通被罚款10亿美元。In Mr Cook’s case, the question is how much of Apple’s investment in Didi is motivated by business sense, and how much of it is an effort to smooth things over with the leadership in China, where the iPhone maker has faced a series of setbacks this year. In April the group’s iTunes services became unavailable in China and in May Apple lost an intellectual property court case against a little-known leather accessories manufacturer that uses “IPHONE” as a trademark on its purses and wallets.就库克而言,问题在于苹果投资滴滴在多大程度上是出于商业考量,在多大程度上是一种旨在缓和与中国领导层关系的努力。今年,iPhone已遭到了一系列挫折。4月,苹果的iTunes视频务在中国无法使用,5月,苹果在一起知识产权纠纷案中输给了一家不知名的皮具配饰制造商,该公司把“IPHONE”商标用在皮夹和钱包类商品上。In contrast Facebook won a trademark case days later against a Chinese company using the brand name “face book”, in a sign that official attitudes could be softening towards the world’s largest social network.与此形成对照的是,Facebook在几天后的商标案中告赢了一家使用“face book”品牌的中国企业,表明中国官方对这家世界最大社交网络公司的态度可能在软化。Apple is also grappling with declining iPhone sales, which fell by a sharp 26 per cent in China last quarter, compared with a 16 per cent overall fall.苹果也在努力应对iPhone销量下降的局面。上一季度,苹果在华销量大减26%,总体销量则减少16%。Jia Jinghua, who covers the domestic technology industry for the Sina Tech news agency, said: “Cook is clearly keen to curry favour with Chinese authorities and with Chinese markets.为新浪科技(Sina Tech)报道中国国内科技行业的贾敬华说:“库克非常急切地讨好中国当局和中国市场。”“He will take advantage of the latest investments into Didi to pay visits to key ministries.”“他将利用最近投资滴滴的机会,拜访中国的关键部委。”Apple declined to comment on Mr Cook’s China itinerary.苹果拒绝就库克的中国之行置评。The visit is his eighth to China since taking over as Apple chief, and is unlikely to be his last.这是库克接任苹果首席执行官以来第8次访问中国,也不太可能是他最后一次来中国。As one user of Weibo, China’s version of Twitter, commented: “Cook, how many Didi rides does it take to make back bn?”正如中国版Twitter新浪微的一名用户所:“库克,滴滴汽车载客多少次才能赚回10亿美元?” /201605/444179成都矫正牙齿去哪家医院

郫县美白牙价格Poor battery life is the number one complaint when it comes to smartphones and laptops. As a wireless society, having to tether ourselves down to power up our gadgets seems more and more a nuisance. And while researchers are looking into wireless charging, if batteries were better we would have to worry less.电池寿命短是智能手机和笔记本电脑的头号难题。在无线社会里,设备线充对我们来说似乎越来越成为一件烦人的事情。虽然研究人员正在寻找无线充电的办法,但如果有更好的电池,那么我们的忧虑也可以减轻了。Now, a new technology promises just that. Researchers from the University of California, Irvine, have invented a nanowire-based battery that can be recharged hundreds of thousands of times, a significant leap towards a battery that doesn#39;t require replacing.现在,一项新的技术的可以做到这点了。来自加利福尼亚大学欧文分校的研究人员发明了一种纳米线电池,该电池可以充电几十万次而不用更换,这是电池发展的一大飞跃。Nanowires possess several ideal characteristics for electric storage and transmission. They are highly conductive and thousands of times thinner than a human hair, which means they can be arranged to provide a large surface area for electron transfer. Unfortunately, nanowires are usually very fragile and don#39;t do well after repeated charging and discharging.纳米线具有蓄电和传输方面的若干理想特性。它们具有高导电性,并且比人类的头发细几千倍,这意味着它们可以为电子转移提供一个巨大的表面区域。不幸的是,纳米线通常是非常脆弱的,并且会在反复充放电后性能会有所降低。The researchers, whose findings are published in the American Chemical Society#39;s Energy Letters, have coated gold nanowires in manganese dioxide and cocooned them in a Plexiglas-like gel. This combination keeps all the properties of the nanowires#39; intact and makes them resistant to fractures.将这项研究结果发表在《美国化学学会·能源通讯》上的研究人员给金质纳米线包了一层壳,并用树脂玻璃之类的凝胶薄层进行包裹。这种结合使纳米线的所有性能保持不变,并使其耐折损。Mya Le Thai, the lead study author, has charged and discharged the battery up to 200,000 times without breaking the nanowires and without loss of capacity.这项研究的带头人妙莱泰已经给电池进行了200000次充放电的操作,之后发现纳米线并没有破损,电池容量也没有损失。;Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,; said senior author Reginald Penner, chair of UCI#39;s chemistry department, in a statement. ;She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.;;妙莱泰不停在测试,她给金质纳米线包了一层壳并开始给纳米线充放电,; 加利福尼亚大学欧文分校化学系主任、资深作家雷金纳德在一份声明中说。;她发现,只要用这种凝胶,她就可以充放电成百上千次而不失去任何容量。;;That was crazy,; he added, ;because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.;;这太疯狂了,;他补充说道,;因为最多经过5000、6000或7000个充电周期,这些物质一般都会失去作用。;The researchers believe that the combination of the PMMA (plexiglass-like) gel electrolyte and the magnesium oxide gives flexibility and structure to the nanowires, preventing cracking and thus extending their operational life.研究人员认为,有机玻璃等凝胶电解质和氧化镁的结合物为纳米线提供了可以防止其开裂的灵活性和结构,从而延长其使用寿命。;The coated electrode holds its shape much better, making it a more reliable option,; Thai said. ;This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.;;被涂层的电极维持自身形态的能力要强得多,因此是更可靠的选项。; 妙莱泰说。;这项研究明,以纳米线为主的电池的电极使用寿命长,我们可以把此类电池变成现实。; /201605/441309 成都最权威牙科医院绵竹市人民医院黄黑牙烟渍牙价格
