As a key Chinese national project, Xiaolangdi Hydro Project is the largest of its kind on the Yellow River and second only to the Three Gorges project on the Yangtze River. It consists of a 1617m-long, 154m-high dam, silt-discharge channels and underground generating units. Preparatory work began in 1991. Main orders were placed in September 1994. One of the landmark events of the project involved diverting the Yellow River. This took place on 28 0ctober 1997 and became a national occasion. The dam received state approval and started storing water in October 1999.It was connected to the grid in January in 2000 and the whole projed was completed in 2001.在河南省洛阳以北40千米处,一座现代化的特大型水利枢纽,小浪底水利枢纽工程,屹立在黄河最后一段峡谷之上。小浪底水利枢纽工程现为黄河上最大的水利工程,仅次于长江三峡水利枢纽工程,属中国国家重点项目。小浪底工程由拦河大坝(坝顶长度1617米,坝高154米)、泄洪建筑物和引水发电系统组成。小浪底工程1991年9月开始前期工程建设,1994年9月主体工程开工。1997年10月28号大坝顺利完成截流,1999年10月经政府许可开始蓄水。2000年元月首台机组并网发电,2001年底主体工程全面完工。Xiaolangdi Project, designed to trap and flush sediments on the lower reaches of the Yellow River, could cope during the summer flood season. Xiaolangdi Hydro Project has been subjected to devastating Yellow River floods and has played an irreplaceable role in the agricultural area alongside.In addition, the l,836mw Xiaolangdi Project is generating 5. 1 billion kwh of electricity a year.Xiaolangdi is a multi-purpose project for dredging, flood control, ice control, industrial and municipal water supply and hydroelectric power.It is the key project of Yellow River Projects, considered as one of the most complicated and challenging hydroelectric projects in the world.黄河小浪底水利枢纽工程的建成有效地控制了黄河下游沉积物,基本解除黄河下游凌汛威胁。小浪底水利枢纽工程不仅时刻保障着中国母亲河的岁岁安澜,也为沿线农业地区发挥着不可取代的关键性作用。除此之外,小浪底电站总装机183.6万千瓦,年平均发电量51亿千瓦时。小浪底水利枢纽工程是黄河干流上的一座集减淤、防洪、防凌、供水灌溉、发电等为一体的大型综合性水利工程,是治理开发黄河的关键性工程,被中外水利专家称为世界上最复杂的水利工程之一,是最具挑战性的工程。 /201603/430085上饶市激光美白肌肤多少钱 Good news for soda lovers: Scientists appear to be one step closer to being able to regenerate teeth in humans. A study in Developmental Biology explains how sharks and other marine life are able to regrow teeth continuously throughout their lives.告诉碳酸饮料爱好者一个好消息:科学家向人类牙齿再生技术又迈进了一步。《发育生物学》上刊登了一项研究,向我们解释了鲨鱼及其它海洋生物可以终生不断再生牙齿的原理。Until now, that process had been ;poorly understood and [remained] virtually uncharacterized from a developmental genetic standpoint.; Researchers at the University of Sheffield studying the embryos of catsharks discovered a ;special set of epithelial cells; called dental lamina that are responsible for regenerating teeth, according to a press release.人们此前对鲨鱼牙齿的再生过程“了解甚少”,认为它“一直是发育遗传理论中的特例”。据报道,英国谢菲尔德大学负责猫鲨胚胎研究的学者发现了一种名为牙板的“特殊上皮细胞群”,它能再次发育出牙齿。Those genes goes back 450 million years and are likely responsible for producing the first teeth in vertebrates, as well as generating all the teeth since, including those in humans. In fact, humans have the same dental lamina, but they produce teeth only twice (;baby; teeth, then the adult versions) before the cells disappear. Researchers believe it#39;s possible for this research to eventually help people who#39;ve lost teeth.这种基因的存在可以追溯到4.5亿年前,可能正是因为它,脊椎动物(包括人类)才长出了第一批牙齿,以及之后的所有牙齿。事实上,人类也有相同的牙板,但人类的牙板在牙齿发育完两次(即乳牙和恒牙)之后,就消失了。研究人员认为,这项研究很有可能最终会帮助缺牙患者重新拥有牙齿。;The Jaws films taught us that it#39;s not always safe to go into the water, but this study shows that perhaps we need to in order to develop therapies that might help humans with tooth loss,; says researcher Dr. Gareth Fraser.研究人员加雷斯·弗雷泽士说:“《大白鲨》这部电影告诉我们,人类进入海里可能遭遇危险。但我们的研究表明,为了帮缺牙患者找到修复方法,或许我们还是有必要入海(研究海洋生物)。” /201602/427445上饶地区人民医院激光脱毛多少钱

武夷山做激光去毛多少钱Shenzhou I Experimental Spacecraft“神舟一号”飞船Nov. 20, 1999, China successfully launched Shenzhou I experimental spaceship on a LM-2F launch vehicle in Jiuquan Satellite Launch Center, which laid solid foundation for realizing the strategic target for manned space flight. Four orbital test flights of the Shenzhou spacecraft were conducted without crews. Remained in orbit for 21 hours, it made 14 0rbits around the Earth carrying a dummy astronaut, experimental seeds, national flags and a banner with signatures of participating engineers and scientists and after that the descent module lands in central Inner Mongolia Autonomous Region the next day.神舟一号飞船是中华人民共和国载人航天计划中发射的4艘无人飞船的第一艘实验飞船。飞船于1999年1 1月20日在酒泉航天发射场成功发射,承担发射任务的是在“长征2号”捆绑式火箭的基础上改进研制的“长征2号”F载人航天火箭。飞船携带一个飞行员模型、一些实验种子,国旗和一面带有航天工程师和科学家签名的横幅绕地球飞行14圈后,顺利降落在内蒙古中部地区的着陆场,飞船在太空中共飞行了21个小时。The unmanned spacecraft consists of orbit, descent and propulsion modules. The orbit module is the place where astronauts live and work. The descent cabin lies in the middle of the spaceship, and is the astronauts cabin and the command and control center. It is a airtight structure with a hatch on the top for astronaut to get in and out of the descent cabin and enter the orbital module, and it is the only landing part of the spaceship to return into the air and to land on the earth. In advancement spacecraft has two solar cell wings, attached to the outside of the instrument propulsion module below the descent cabin. The two solar cell wing total area of 24.48 m2, which are deployed after launch and supply the power distribution. Shenzhou I experimental spaceship is the important milestone in China#39;s spaceflight history.飞船由轨道舱、返回舱和推进舱组成。轨道舱位于飞船的前段,通过舱口与后面的返回舱相通,轨道舱是宇航员在轨飞行期间的生活舱、试验舱和货舱。飞船中部的返回舱是飞船的指挥控制中心,航天员乘坐其上天和返回地面。推进舱位于飞船的后部,主要用于飞船的姿态控制、变轨和制动。除此之外,推进舱两侧装有20多平方米的主太阳能电池阵。飞船发射后两侧太阳能电池阵机翼打开为前进中的飞船提供电力。“神舟一号”无人试验飞船是中国载人航天工程的首次飞行,标志着中国在载人航天飞行技术上有了重大突破,是中国航天史上的重要里程碑。 /201603/430084 HONG KONG — The ed States says it will expand air-quality monitoring at some overseas diplomatic missions, following several years of reporting pollution data in China.香港——在对中国污染数据进行报告数年后,美国表示将在部分海外外交代表团驻地增加空气质量监控。The goal is to increase awareness of the health risks of outdoor air pollution, which easily sps across borders, Secretary of State John Kerry said in announcing the program on Wednesday.国务卿约翰·克里(John Kerry)周三在宣布该项目时说,该项举措的目标是提高对户外空气污染带来的健康风险的认知,空气污染很容易跨境进入别国。The program is intended to help ed States citizens abroad reduce their exposure to pollution and to help other countries develop their own air-quality monitoring through training and exchanges with American experts, he said.他说,该项目旨在帮助身在海外的美国公民减少与污染的接触,并协助其他国家通过培训以及与美国专家的交流,发展自己的空气质量监测。“We’re hoping that this tool can also expand international cooperation when it comes to curbing air pollution,” Mr. Kerry said.“我们希望,该手段也可以在控制大气污染方面增加国际合作,”克里说。The program, run in conjunction with the Environmental Protection Agency, will begin to operate in India in a few months. New Delhi has some of the world’s worst air pollution, and residents there are becoming increasingly concerned about the dangers.这个项目将与美国国家环境保护局(Environmental Protection Agency)共同运作,于几个月后在印度上线。新德里是世界上大气污染最严重的城市之一,当地居民越来越关注污染的危险性。American diplomatic missions will also monitor air quality in Vietnam, Mongolia and elsewhere, Mr. Kerry said.克里表示,美国外交使团驻地也将监测越南、蒙古等国的空气质量。In 2008, the ed States Embassy in Beijing began monitoring levels of PM 2.5 — fine airborne particles that are particularly dangerous for human health — and posting hourly ings on Twitter.2008年,美国驻北京大使馆开始监测PM2.5(空气中危害人类健康的细微颗粒)值,并每小时在Twitter上发布实时数据。The move angered the Chinese government, which said the information could threaten social stability. But the step also helped pressure Chinese environmental officials to expand their monitoring of air pollution and begin publishing their own air-quality reports.中国政府对该举措表示愤怒,并表示信息可能会威胁社会稳定。但该举措也协助向中国环境官员施压,推动其增强空气质量监测,并开始发布自己的空气质量报告。 /201502/360782上饶上睑下垂整形手术上饶韩美整形医院玻尿酸隆鼻多少钱
