什么叫做航天飞机

航天飞机(Space Shuttle,又称为太空梭或太空穿梭机)是可重复使用的、往返于太空、宇宙和地面之间的航天器,结合了飞机与航天器的性质。航天飞机是一种有人驾驶可重复使用的航天器,它既能像火箭一样垂直起飞,像太空飞船一样在轨道上运行,又能像飞机一样水平着陆。航天飞机一般可乘坐7名航天员,其中有3名机组人员,4名科学技术专家。航天飞机在轨道上运行时,可完成释放卫星、回收及维修卫星、进行各种微重力科学实验等多种任务。更多具体信息请查看链接http://baike.so.com/doc/5415229-5653374.html

航天飞机和空天飞机的区别??

它与航天飞机的区别在于,它是一种运载火箭、航空器、航天器结合在一起的飞行器。又叫航空航天飞机。在它上面既装有火箭发动机又装有冲压空气喷气发动机。它可以从地面上像飞机一样水平起飞,也可以由大型飞机载带到空是起飞。在30千米以上高空,能以5倍~15倍音速像飞机一样在大气层中巡航飞行,如将速度提高到25倍音速,到达大气层边缘时,启动火箭发动机可以进入太空。 研制空天飞机要解决许多复杂的技术问题和材料问题。如防热、耐高温(摄氏2760度)结构材料问题、超高音速冲压喷气发动机问题等。 美国的洛克希德-马丁公司研制的X-33空天飞机,计划在1999年进行亚轨道10次飞行。

航天飞机的速度?

美国太空总署给你的回答:The Space Shuttle speed goes from 0 mph to 17,500 mph in 8.5 minutes (this is when the external fuel tank separates from the Shuttle). Two minutes after launch the solid rocket boosters separate; at this time the speed is 3,438 mph and increasing rapidly. While in orbit the Shuttle"s speed is 17,500 mph. When reentry or blackout occurs, the Shuttle is traveling at 16,700 mph. After reentry the Shuttle uses Earth"s atmosphere to slow down. Landing speed ranges from 213 to 226 mph (343 to 364 kilometers). 航天飞机可以在8.5分钟内,由静止加速到17500英里/小时(这是当外部燃料箱和航天飞机分离时的速度)。发射两分钟后,固体火箭推进器会和航天飞机分离,此时的速度是3438英里/小时,并且航天飞机还在持续迅速加速。航天飞机在轨速度一般是17500英里/小时,但是当返回或者进入黑障的时候,航天飞机的速度会在16700英里/小时。进入地球大气层后,航天飞机会逐步减速,最后的着陆速度在213~226英里/小时之间(合343~364公里/小时)。*那最后航天飞机的着陆速度就该是364*1000/3600=101米/秒

美国为什么淘汰了航天飞机,而不继续?

际上每年只有7~8次,每次发射费用约4。4亿美元,年使用成本超过30亿美元。  航天飞机太重、太脆弱、太复杂  航天飞机列入“一类关键性”清单的部件就有750个,这些部件一出问题就有灾难后果,保养4架航天飞机需要30000人。直至2005年3月22日,NASA还发现“发现号”尾部减速板驱动装置存在齿轮装反的潜在安全隐患,却20余年未被发现航天飞机虽然技术先进,但是,技术难度极大,风险也就大,而且安全性能不是太高。所以就给淘汰了。DWa超级大本营军事

英语演讲稿:英语演讲稿:The Space Shuttle

12月23日 liuxue86.com英语频道特为大家准备相关的学习资料,希望对大家有用。 Ladies and Gentlemen, I"d planned to speak to you tonight to report on the state of the union , but the events of earlier today have led me to change those plans. Today is a day for mourning and remembering. Nancy and I are pained to the core by the tragedy of the shuttle Challenger. We know we share this pain with all of the people of our country. This is truly a national loss. Nineteen years ago, almost to the day, we lost three astronauts in a terrible accident on the ground. But we"ve never lost an astronaut in flight. We"ve never had a tragedy like this. And perhaps we"ve forgotten the courage it took for the crew of the shuttle. But they, the Challenger Seven, were aware of the dangers, but overcame them and did their jobs brilliantly. We mourn seven heroes: Michael Smith, Dick Scobee, Judith Resnik, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe . We mourn their loss as a nation together. For the families of the seven, we cannot bear, as you do, the full impact of this tragedy. But we feel the loss, and we"re thinking about you so very much. Your loved ones were daring and brave, and they had that special grace, that special spirit that says, "Give me a challenge, and I"ll meet it with joy." They had a hunger to explore the universe and discover its truths. They wished to serve, and they did. They served all of us. We"ve grown used to wonders in this century. It"s hard to dazzle us. But for twenty-five years the United States space program has been doing just that. We"ve grown used to the idea of space, and, perhaps we forget that we"ve only just begun. We"re still pioneers. They, the members of the Challenger crew, were pioneers. And I want to say something to the schoolchildren of America who were watching the live coverage of the shuttle"s take-off. I know it"s hard to understand, but sometimes painful things like this happen. It"s all part of the process of exploration and discovery. It"s all part of taking a chance and expanding man"s horizons. The future doesn"t belong to the fainthearted; it belongs to the brave. The Challenger crew was pulling us into the future, and we"ll continue to follow them. I"ve always had great faith in and respect for our space program. And what happened today does nothing to diminish it. We don"t hide our space program. We don"t keep secrets and cover things up. We do it all up front and in public. That"s the way freedom is, and we wouldn"t change it for a minute. We"ll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue. I want to add that I wish I could talk to every man and woman who works for NASA, or who worked on this mission and tell them: "Your dedication and professionalism have moved and impressed us for decades. And we know of your anguish. We share it." There"s a coincidence today. On this day three hundred and ninety years ago, the great explorer Sir Francis Drake died aboard ship off the coast of Panama . In his lifetime the great frontiers were the oceans, and a historian later said, "He lived by the sea, died on it, and was buried in it." Well, today, we can say of the Challenger crew: Their dedication was, like Drake"s, complete. The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and "slipped the surly bonds of earth" to "touch the face of God." Thank you. 常识普及:英语演讲稿种类:1。叙述式:向听众陈述自己的思想、经历、事迹,转述自己看到、听到的他人的事迹或事件时使用的。叙述当中,也可夹用议论和抒情。2。议论式:摆事实、讲道理,既有事实材料,又有逻辑推断,立场坚定,旗帜鲜明。3。说明式:对听众说明事理,通过解说某个道理或某一问题来达到树立观点的目的。

航模类科学小知识短一点

1.关于航天的知识,短一点 航空航天技术 为航空航天活动的顺利进行而创立的一系列高级复杂的施工作业程序。 它涉及人力资源配置,设备仪器搭配与安装使用等艰深的学术作业。是国家,民族,乃至整个人类发展的高度追求。 在现代航空和航天工程中电子系统是重要的系统之一。 它按功能分为通信、导航、雷达、目标识别、遥测、遥控、遥感、火控、制导、电子对抗等系统。 各种系统一般包括飞行器上的电子系统和相应的地面电子系统两部分,这两部分通过电磁波传输信号合成为一个系统。和这些电子系统有关的电子理论和技术有通信理论、电磁场理论、电波传播、天线、检测理论和技术、编码理论和技术、信号处理技术等,而微电子技术和电子计算机技术则是提高各种电子系统性能的基础。它们的发展使飞行器上的电子系统进一步小型化和具有实时处理更大量数据的能力,进而使飞机的性能(机动能力、火控能力、全天候飞行、自动着陆等)大为提高,航天器的功能(科学探测、资源勘测、通信广播、侦察预警等)日益扩大。 一、航空航天飞行器上电子设备的特点是: ①要求体积小、重量轻和功耗小;②能在恶劣的环境条件下工作;③高效率、高可靠和长寿命。 在高性能飞机和航天器上,这些要求尤为严格。飞机和航天器的舱室容积、载重和电源受到严格限制。 卫星上设备重量每增加1公斤,运载火箭的发射重量就要增加几百公斤或更多。导弹和航天器要承受严重的冲击过载、强振动和粒子辐射等。 一些航天器的工作时间很长,如静止轨道通信卫星的长达7~10年,而深空探测器的工作时间更长。因此,航空航天用的电子元器件要经过极严格的质量控制和筛选,而电子系统的设计需要充分运用可靠性理论和冗余技术。 二、航空航天电子技术的主要发展方向是: ①充分利用电子计算机和大规模集成电路,提高航空航天电子系统的综合化、自动化和智能化水平;②提高实时信号处理和数据处理的能力和数据传输的速率;③发展高速率和超高速率的大规模集成电路;④发展更高频率波段(毫米波、红外、光频)的电子技术;⑤发展可靠性更高和寿命更长的各种电子元器件。 2.航天科技小知识 一、航空航天飞行器上电子设备的特点是:

Shuttle,正式名称为太空梭或太空穿梭机)是可重复使用的、往返于太空和地面之间的航天器。航天飞机并不是飞机,并不属于飞机的范畴。 它既能像运载火箭那样把人造卫星等航天器送入太空,也能像载人飞船那样在轨道上运行,还能像滑翔机那样在大气层中滑翔着陆。航天飞机为人类自由进出太空提供了很好的工具,它大大降低航天活动的费用,是航天史上的一个重要里程碑,最早由美国研发。 1986年的1月28日,美国“挑战者”号航天飞机在第10次发射升空后,因助推火箭发生事故凌空爆炸,舱内7名宇航员(包括一名女教师)全部遇难,此次事故除了造成人员死亡,还造成了12亿美元的直接经济损失和所有航天飞机停飞3年的结果。 2003年2月1日,美国哥伦比亚号航天飞机在结束了为期16天的太空任务之后,返回地球,但却在降落前发生空中解体,宇航员全部遇难。这些事件都表明,航天飞机的安全性其实并不高。 扩展资料: 组成部分 航天飞机实际上是一个由轨道器、外贮箱和固体助推 火箭助推器 器组成的往返航天器系统,但人们通常把其中的轨道器称作为航天飞机。 1、轨道器:轨道器是航天飞机的核心部分,是整个航天飞机系统中唯一可载人、可重复使用的部分。 2、固体助推器:固体助推器的作用是助推,用于补充主发动机推力的不足。以供再用。 3、外贮箱:航天飞机的主发动机是液体火箭发动机,推进剂是液体燃料液态氧和液态氢。液体推进剂不装在航天飞机上,而是装在一个独立的可以抛弃的外贮箱里面。采用这种结构形式,可以减少航天飞机轨道器的尺寸和重量,否则航天飞机的轨道器非常庞大。 美国研制过5种型号的航天飞机:哥伦比亚号航天飞机、挑战者号航天飞机、发现号航天飞机、亚特兰蒂斯号航天飞机和奋进号航天飞机。 苏联研制过暴风雪号航天飞机,1988年对暴风雪号航天飞机成功地进行了无人轨道试飞,其后,由于苏联1991年解体,计划终止。 参考资料来源:百度百科-航天飞机 4.航模基础知识 去百度文库,查看完整内容> 内容来自用户:刘中升 航模基础知识手册 资料针对无线电遥控类固定翼飞机2014.06.18

5.我需要航模知识 航空模型航空模型是各种航空器模型的总称。 它包括模型飞机和其他模型飞行器。 航空模型活动从一开始就引起人们浓厚的兴趣,而且千百年来长盛不衰,主要原因就在于它在航空事业的发展和科技人才的培养方面起着十分重要的作用。 (1)航空模型是探索飞行奥秘的工具。人类自古以来就幻想着飞行。 昆虫、鸟禽、风吹起树叶和上升的炊烟,都曾引起过人类飞行的遐想。西汉刘安在《淮南子》中记载着后羿的妻子嫦娥偷食了长生药而飞上月宫的美妙故事。 这反映了古人对飞行的追求和向往。 在载人的航空器出现之前,人类就创造了许多能飞行的航空模型,不断地探索着飞行的奥秘。 距今2000多年前的春秋战国时期,我们的祖先就制作出能飞的木鸟模型。《韩非子》中记载着:“墨子为木鸢,三年而成,飞一日而败。” 宋朝李鸢等人编的《太平御览》中也有“张衡尝作木鸟,假以羽翮,腹中施机,能飞数里”的记载。另外,还制作出种类繁多的孔明灯、风筝和竹蜻蜒等。 唐代以后,我国的风筝传到国外,在世界上流传开来。西方有人用风筝做飞行试验,探索制造飞机的可能。 美国的莱特兄弟是世界上第一架飞机的制造者,他们的飞机在1903年12月17日试飞成功。他们就是先用大风筝进行种种试验,然后制造出滑翔机,解决了升降、平衡、转弯等问题,最后才把飞机制造成功的。 飞机发明之前,航空模型具有强烈的探索性质,在飞机发明之后,航空模型仍然是研究航空科学的必要工具。每一种新飞机的试制,都要先在风洞里用模型进行试验,甚至连航天飞机这样先进的航空器,也要经过模型试验阶段,取得必要的数据,才能获得成功。 (2)航空模型是很有实用价值的器具。我国汉代就有用风筝测量距离和传递信息的。 随着航空模型的发展,特别是无线电遥控模型飞机的日臻完善,航空模型的用途越来越广泛。 例如,可以利用无线电遥控模型飞机作为部队和民兵对空射击训练的靶机。 在训练的时候,通过无线电遥控设备控制航模靶机完成直线飞行、转弯、上升、俯冲等飞行动作,甚至在靶机上完成空投降落伞、发射模型火箭、投放炸弹、施放拖靶等特技动作。在实弹射击时候,可以在航模靶机尾部几十米远处拖拽一个彩色靶袋,以靶袋作为目标,避免击毁靶机。 又如,在无线电遥控模型飞机上装上摄影机,就可以对地面进行航空摄影,拍摄一些人们不容易接近的野生动植物,甚至可以拍摄一些危险性很大的惊险镜头或战斗场面等。 另外,可以利用航模飞机携带农药灭虫,利用航模飞机拖一根尼龙线从一个山头到另一个山头,然后换成钢索,进行高山架线。 还可以利用航模飞机飞入云层,施放催化剂,进行人工降雨,等等。 (3)航空模型是普及航空知识的玩具。 航空模型活动在普及航空知识、培养航空科技人才方面所起的作用是很大的,许多著名的航空学家,小时候都非常喜爱航空模型。美国的莱特兄弟小时候就爱玩飞螺旋(竹蜻蜓),从而产生对航空事业的浓厚兴趣。 美国登月飞船阿波罗11号船长阿姆斯特朗,小时候也酷爱航空模型,他在家里的地下室安装了一个风洞,用来试验自己制作的模型飞机,这无疑对他成为世界上第一个踏上月球的人有着巨大的影响。我国也有许多著名的飞机设计师、火箭设计师、飞行员等,小时候就是航模爱好者。 另外,航空模型还是一种非常吸引人的娱乐玩具。春光明媚,千姿百态的风筝随风飘荡;夏日朗朗,五颜六色的飞盘划出一道道弧线,秋高气爽,各式各样的模型飞机在蓝天中翱翔;冬天恬静,彩色缤纷的热气球冉冉升起。 所有这些把人们的生活装点得更加丰富多彩。 在飞机发明之后,航空模型作为普及航空知识的工具和娱乐玩具的作用更加突出。 为了推动航空事业的发展,1905年10月,在法国成立了国际航空联合会。它下设国际航空模型委员会,负责制定航空模型竞赛规则,组织国际航空模型竞赛活动。 中国是国际航空联合会成员,积极参加国际航空模型竞赛活动,并取得了优异的成绩。在国内,经常举行全国性和地方性的航空模型竞赛,以推动航空模型活动和普及航空科学知识。 航模知识简介 航空模型运动是以操纵、放飞自制或装配的模型航空器进行户外活动、训练比赛或创纪录飞行的一项科技性较强的运动。 现代航空模型运动分为自由飞行、线操纵、无线电遥控、仿真和电动等五大类。 按动力方式又分为:活塞发动机、喷气发动机、橡筋动力模型飞机和无动力的模型滑翔机等。航空模型的最大升力面积500平方分米;最大重量25千克;活塞发动机最大工作容积250毫升。 航空模型的竞赛科目有:留空时间、飞行速度、飞行距离、特技、“空战”等。目前世界锦标赛设有30个项目,隔年举行一次。 航空模型还设有专门记录各项绝对成绩 的纪录项目。目前国际航联共设90项航空模型世界纪航空模型运动的生命力在于它的趣味性和知识性。 亲手制作的矫健雄鹰翱翔蓝天,往往会使青少年产生美好的遐想,激励它们不停的追求,使他们从兴趣爱好走进献身祖国航空事业的理想。参加这项活动还可以学到许多科技知识,培养既善于动脑又善于动手和克服困难勇于进取的优秀品质,促进德智体全面发展。 随着人民物。 6.有关于航模知识 航空模型 航空模型是各种航空器模型的总称。它包括模型飞机和其他模型飞行器。

7.身边的科学小知识50个 为甚么星星会一闪一闪的? 我们看到星闪闪,这不是因为星星本身的光度出现变化,而是与大气的遮挡有关。 大气隔在我们与星星之间,当星光通过大气层时,会受到大气的密度和厚薄影响。大气不是绝对的透明,它的透明度会根据密度的不同而产生变化。所以我们在地面透过它来看星星,就会看到星星好像在闪动的样子了。 2. 为甚么人会打呵欠? 当我们感到疲累时,体内已产生了许多的二氧化碳。当二氧化碳过多时,必须再增加氧气来平衡体内所需。因为这些残留的二氧化碳,会影响我们身体的机能活动,这时身体便会发出保护性的反应,于是就打起呵欠来。 打呵欠是一种深呼吸动作,它会让我们比平常更多地吸进氧气和排出二气化碳,还做到消除疲劳的作用呢。 3. 为甚么蛇没有脚都能走路? 蛇的身上有很多鳞片,这是它们身上最外面的一层盔甲。鳞片不但用来保护身体,还可以是它们的「脚」。 蛇向前爬行时,身体会呈S形。而每一片在S形外边的鳞片,都会翘起来,帮助蛇前进时抓住不平的路面。这些鳞片跟蛇的肌肉互相配合,并能推动身体向前爬行,所以蛇没有脚也可以走动呀! 4. 为甚么向日葵总是朝着太阳开花 向日葵花盘下面茎部的地方,含有一种叫做「植物生长素」的物质。这物质有加速繁殖的功用,但却具有厌旋光性,每遇到光线时,便会跑到背光的一面去。 所以太阳升起时,向日葵茎部便马上躲到背光的一面去,看起来整棵植物就向着太阳的方向弯曲了。 5. 为甚么人老了头发便会变白? 我们的头发中有一种叫「黑色素」的物质,黑色素愈多头发的颜色便愈黑。而黑色素少的话,头发便会发黄或变白。人类到了老年时,身体的各种机能会逐渐衰退,色素的形成亦会愈来愈少,所以头发也会渐渐变白啊! 6. 为甚么萤火虫会发光? 萤火虫会发光因为在它们的腹部末端有发光器,发光器内充满许多含磷的发光质及发光酵素,使萤火虫能发出一闪一闪的光。 萤火虫发光的目的,除了要照明之外,还有求偶、警戒、诱捕等用途。这也是它们的一种沟通的工具,不同种类萤火虫的发光方式、发光频率及颜色也会不同,它们藉此来传达不同的讯息。 7. 为甚么肚子饿了会咕咕叫? 肚子饿了便会咕噜咕噜地叫,这是因为之前吃进的食物快消化完,胃里虽然空空的,但胃中的胃液仍会继续分泌。这时候胃的收缩便会逐渐扩大,内里的液体和气体便会翻搅起来,造成咕噜咕噜的声音。 下次不要再为肚子咕咕叫而感到尴尬啊

有谁知道关于神州六号的英语短文

别像超女一样写错别字,是神舟六号1.On October 17, after China carries the human aerospace year airship"god boat" six to continue the divine land five successes returns, theload bearing two astronautics heroes succeed once more the return,China become continues US, after Soviet Union, third has the abilityload bearing multi- people to enter the outer space the country.Enters the outer space, since is long-cherished wish which thehumanity always has longed for even in dreams!2.BEIJING, Oct. 17 (Xinhua) -- The re-entry capsule of China"s Shenzhou-6 spacecraft, carrying taikonauts Fei Junlong and Nie Haisheng, landed on earth safely at 4:33 a.m. Monday, marking a "complete success" of China"s second manned space mission after it put the first Chinese national in space two years ago. Chinese top legislator Wu Bangguo declared China"s second manned space mission a "complete success," claiming it a "milestone" in China"s space technology development and its space experiments with human participation. "The successful mission is of great significance for elevating China"s prestige in the world, promoting China"s economic, scientific and national defense capabilities and consolidating thenational cohesiveness," he said at the Beijing Aerospace Command and Control Center. Both taikonauts are "in fine conditions," doctors said after physical checkup upon landing. They landed just 1 km away from the preset spot after a 115-hour-and-32-minute spaceflight, which was more than five times that of China"s maiden manned spaceflight twoyears ago. Fei and Nie stepped down a ladder from the capsule by themselves, and were seated for a bouquet of flowers and to get used to Earth"s gravity. "We feel fine," said all-smile Fei. Nie thanked all the Chinesepeople for their "concern and support." Both waved flowers to theexcited welcoming crowd. They were later fed with chocolate, Chinese herbal tea. Nie seemed in a very good appetite and took a bowl of instant noodle, before the two men were flown by two Super Puma helicopters to a nearby airport where they will head for Beijing by a special plane. The space mission have gripped the sight of the whole nation inthe past five days. "We can have a final laughter," beaming Liu Yu, commanding chief of the rocket system told Xinhua. "It was a mission perfectly fulfilled." Television pictures showed parents of the two taikonauts burst into tears when they saw their sons emerging from the spacecraft early Monday morning. Chinese president Hu Jintao were present at the Beijing Aerospace Command and Control Center to watch the lift-off on Wednesday and talked with taikonauts on Saturday. Chinese premier Wen Jiabao was at the launch site to see off the two men with bestwishes before the launch. Luckily, Nie spent his 41st birthday in space and received a phone call from his wife and daughter. The joyful daughter"s sweet song "Happy Birthday to You" has warmed the hearts of millions of Chinese television viewers. Fei and Nie blasted off Wednesday morning on China"s second manned space mission. Before landing, Shenzhou-6 have been racing around the Earth one circle in every 90 minutes 343 km above the Earth at a speed of 7.9 km per second. It flew 3.25 million kilometers in space. Fei and Nie have conducted a series of unprecedented experiments on the spacecraft, including the maneuvers between the orbital and re-entry capsules, taking on and off space suits, using space toilet and the self-test of blood pressure. During China"s maiden space flight in 2003, lone astronaut YangLiwei never left his seat in the re-entry capsule nor take off hisspace suit. That space mission has made China the third country toput human into space following Russia and the United States.

帮我找一篇关于人类登月的英语短文

Since 1957 the former Soviet Union launched the world"s first artificial Earth satellite, the former Soviet Union and the United States based on the multiple background of the times, carry out competition in the aerospace field, and both astronauts to the moon as a stage victory signs. In subsequent years, the former Soviet Union and Russia in manned spaceflight and the exploration of deep space on the left and many indelible imprint. In order to achieve a lunar landing, the former Soviet Union in the 20th century to the late 1950s to the 1960s, Moon launched a number of unmanned aerial vehicles, for the first time in the world unmanned spacecraft carrying animals from Central flying back to the moon camera to probe the lunar surface soft landing, and developed more than lunar rover. But aerospace experts in the former Soviet Union used to launch lunar spacecraft design a rocket differences: chief designer of the Soviet space Korolev advocated the use of new type of rocket "H1", Qieluomei spacecraft designers and others advocated the "Proton" rocket improvements. The pilot of the two rockets were not successful, a delay of the Soviet lunar landing time. Meanwhile, the United States launched the "Apollo" program, launched by about 300,000 staff, has cost about 25.5 billion US dollars, in 1968, the first manned spacecraft of the moon flight. In 1969, American astronauts on "Apollo 11" spacecraft, the first lunar landing, in which the United States win a race. The setbacks experienced former Soviet Union, began right then used to launch lunar spacecraft "H1" rocket conducted four tests, but all these efforts failed. In 1976 the Soviet Union finally gave up manned lunar flight plan. In the subsequent development of the space shuttle, the former Soviet Union than the United States seven years later, in 1988, launched the "Buran" shuttle 自从1957年原苏联发射了世界上第一颗人造地球卫星,原苏联和美国便基于当时的多重时代背景,在航天领域展开竞赛,并都把宇航员送上月球作为取得阶段性胜利的标志。在以后的岁月中,原苏联和俄罗斯在载人航天、深空探测之路上又留下了诸多不可磨灭的印记。 为了实现登月,原苏联曾在20世纪50年代末至整个60年代向月球发射了多个无人飞行器,在世界上首次实现无人航天器携带动物环月飞行、为月球背面拍照、使探测器在月球表面软着陆,并研制出多辆月球车。但原苏联航天专家在用于发射月球飞船的运载火箭设计上出现分歧:原苏联航天总设计师科罗廖夫主张采用新型火箭“H1”,而航天设计师切洛梅等人主张对“质子”型运载火箭进行改进。对两种火箭的试验均未成功,耽误了原苏联登月的时间。与此同时,美国启动了“阿波罗”计划,发动了约30万工作人员,先后耗资约255亿美元,抢先于1968年实现了载人飞船绕月飞行。1969年,美国宇航员乘坐“阿波罗11”号飞船率先登月,使美国在这一轮竞赛中胜出。 经历这一挫折的原苏联,此后又陆续对用于发射月球飞船的“H1”运载火箭进行了4次试验,但均告失败。1976年原苏联终于放弃了月球载人飞行计划。在随后的航天飞机开发方面,原苏联比美国晚了7年半,于1988年发射了“暴风雪”号航天飞机

工程伦理学的美国工程伦理学发展的特点与态势

在工程师与哲学家、律师、社会学家以及对职业伦理感兴趣群体的合作推动下,工程伦理学取得很大进展,研究了大量的工程伦理问题,澄清了核心的概念,论证了特定的伦理观点,并促使美国工程伦理学呈现出新特点和新趋势,主要表现三个方面: 工程师伦理问题是研究的基础和重点。许多学者从多种角度分析并探究工程师的道德困境。总体来看大致分为三个方面:第一是工程师与伦理的关系问题,虽然人们越来越重视工程中出现的伦理问题,但是许多工程师依然对伦理问题关注不够。肯奈滋 K 哈姆佛瑞(Kenneth K. Humphreys)结合工程师在日常生活所面临的伦理问题,指出工程师的伦理困境以及工程职业的伦理规范和伦理行为的法律必要性。[5]艾德姆德 西巴尔(Edmund G. Seebauer)和罗伯特 拜瑞(Robert L. Barry)则认为必须明确在工程中道德问题的复杂性和道德责任,而工程师所面对的大部分道德议题都是来自于利益冲突,雇主与雇员的关系,环境意识,以及技术对人们的影响等,这些伦理问题也是不同的。[6]第二是工程师的责任问题,特别社会责任问题成为关注的焦点。自从19世纪60年代以后,掀起了一场“ 社会责任运动”,并席卷了美国整个职业。作为发明创造的工程师更是由后台被推向了前台,成为社会责任的主要载体,而倍受瞩目。爱迪温 T 莱顿(Edwin T. Layton)认为这不仅是工程职业的问题,而且是在合作的社会中寻求尊严和自由,更是现代社会一个普遍深入的主题。广大群体如科学家、管理者、工程师以及其他公众也担负社会责任,才能使工程职业健康的发展。[7]技术哲学家斯代芬 H.恩格尔(Stephen H. Unger )指出对于技术的后果,应用和发展技术的人应该负有责任。工程师对于技术的后果负有责任,并且他们的任务之一要告知公众技术的可能结果;同时工程师作为一名雇员,缺少对履行任务所负道德责任的自治,所以需要管理部门、法院法律、工程协会来协调和处理这些问题。[8]但直到今天关于工程师的社会责任问题,依然是工程伦理学持续探讨的一个话题。第三是关于工程师的角色冲突问题。在工程活动中,工程师角色是复杂的、多重的,作为雇员的工程师与作为管理者的工程师,对于风险、安全、忠诚的认识是完全不同的。亨利 派超斯基(Henry Petroski)认为工程师角色不是单纯地工程设计者,还有多种社会角色,其活动受到其他多种因素的影响和制约,所以,对于工程师应该做什么的理解需要把握工程师相关角色的关系。 [9]而关于于工程师未来角色定位,美国国家科学院、国家工程院在《2020年的工程师:新世纪工程学发展的远景》指出工程师应该成为:受全面教育的人,有全球公民意识的人,在商业和公众事务中有领导能力的人,有伦理道德的人。工程伦理教育是工程伦理学发展的途径,是培养工程师伦理道德的重要手段,并在一定程度上推动美国工程伦理建制化发展。1985年,工程与技术认证委员会(the Accreditation Board for Engineering and Technology,ABET)要求美国的工程院校,必须把培养学生“工程职业和实践的伦理特征的认识”作为接受认证的一个条件。2000年,工程与技术认证委员会制定更为具体的方针,当前工程院校正在按照这些方针来操作。但是工程伦理学教育也面临着三方面挑战:第一,工程伦理学的学习如何被理所当然地整合进工科学生所需要的必修课程目录中?第二种挑战,应由谁来教授工程伦理学?第三个挑战,工程伦理学的教学和研究目标是什么?而与这些挑战相关,罗伯特 迈基(Robert E. McG)采取问卷调查发现,对于工程学生进行工程中伦理问题相关的教育与现代工程实践的现实之间存在着重大的鸿沟。而广大学生的期望,即在他们将来的工程职业中所出现的伦理问题,却与普遍应用于工程课堂中的工程伦理问题以及在课堂外频繁遇到的伦理问题很难是相同的。这也促成了一个广泛传播并公开声称的信条 ——更好地成为一个好的工程职业者,而不是成为一个负有道德和社会责任感的工程职业者。而对于实践工程师而言,在最重要的非技术内容上观点是存在分歧的,这也给工程伦理学教师和其他工程教育者带来了严峻的挑战。 [12]工程协会的历史研究,有助于加强工程协会的认识,理解工程专业规范的变化过程,推动伦理规范内容成熟和完善。20世纪80年代在各大工程社团资金的资助下,许多学者对于工程社团的历史进行了专题研究。米切尔 迈克迈龙(Michal McMahon)研究了“新专业主义”,发现电气和电子工程师协会(the Institute of Electrical and Electronics Engineers IEEE)最重要的核心内容之一,指出科学与技术制度化历史中的新方向,在电子工程内部和技术发展的境域中说明社会和职业的变革;布如斯森克莱(Bruce Sinclair)叙述了美国机械工程师协会(the American Society of Mechanical Engineers ASME)的百年历史[14];艾莱克斯 罗兰德(Alex Roland)阐述了关于国家航空顾问协会(the National Advisory Committee on Aeronautics NACA)(国家航空和宇宙航行局(National Aeronautics and Space Administration NASA)的前身)管理和政治的批判历史[15];特瑞 莱纳德斯(Terry S Reynolds)描写了美国化学工程师协会(the American Institution of Chemical Engineers AIChE)历史,提出美国化学工程师协会与环境以及公共政策关系的议题[16]。由于是职业协会赞助,所以他们的历史很少关注到社会责任和伦理,最多也只是工程协会历史中的一小部分,但却有利于促进职业协会制度化发展。 自工程伦理学产生以来,一直有两种研究方法处于主导地位。一种方法是典型真实事件的案例研究方法,著名案例如挑战者号失事、三哩岛核泄露、福特斑马轿车问题等。比较全面以案例来展开研究的是罗萨 B 品库斯等人(Rosa Lynn B. Pinkus)以美国航天飞机主体发动机(the main engine of the space shuttle SSME)的决策、设计、制造为案例,通过跨学科分析其涉及到不确定性和风险的评估,强调工程师是如何识别、表达和解决复杂的伦理难题。并指出三个最基本原则:能力(competence)、责任(responsibility)和西塞罗(Cicero)的第二信条(“保证公众的安全”)作为一个分析框架来表达和解决在实践中产生的伦理问题。另一种方法是对于涉及到工程实践活动的概念、规范和原则的理论分析。如马丁(Mike W. Martin)等就利用如功利主义、权利伦理与义务伦理、美德伦理等基本伦理理论,分析并探讨工程中常见的风险与安全、责任与权利、诚实与欺骗等概念,指出他们的伦理内涵和价值指向。[18]戴维斯(Davis)等人也做出有影响的理论分析工作。这两种“描述性案例研究”与“理论分析研究”是韦伯(Weberian)的“理想模式”,这样一种模式可以在一定范围内聚焦其反面观点。当然这两种方法并不互相排斥,反而有走向融合的趋势,即大量工程伦理案例的描述也进行理论分析,许多工程伦理理论分析研究也利用案例来证明和说明他们的结论。至于说哪种趋向更强主要取决于这两种研究方法在一定的范围内谁更有利于找到结合点 其他研究方法还包括调查研究方法,如罗伯特 迈基通过调查斯坦福大学的工程学生和实践工程师过去五年里所提交的工程伦理问题,发现并指出面向工程伦理主题的多种经验方法的价值。正如理论分析能够阐明具体案例研究的争论,精确和探究的调查工程学生和实践者的观点也同样能够拓宽焦点问题假设。[19]也有少部分学者从语言学角度研究工程伦理学,美国纽约州立大学的J 埃迈图博士(Joe Amato)描述了1944年以来美国工程职业的历史发展,并从本体论角度研究工程设计的理论,在语境中解释了技术。[20]但这种叙述性语境描述也仅仅存在于对历史的考察,在关注现实问题上显得过于空泛。 随着技术发展和工程应用的国际化,工程伦理学研究出现了新的课题和趋势,工程伦理学将反思全球化经济时代围绕技术发展所关涉的所有主要问题。比较突出的包括以下三个方面:第一,关于计算机伦理问题的探讨。计算机与隐私是否造成价值冲突?软件所有权是否应该得到保护?计算机发展所产生的道德责任,是个体责任还是共同责任呢?这些都应该在信息化社会中对“责任”进行探讨。因特网与自由言论问题以及产生的权力关系,涉及到的知识产权问题,计算机导致的失败以及所造成的健康等问题,这些都需要关注和研究。第二,环境伦理问题的倍受关注,工程伦理学把环境伦理作为研究重要内容之一。马丁通过对于工程、生态与经济关系的考察,分析了人类中心主义伦理、非人类中心主义伦理、生态中心主义伦理、经济中心主义伦理的伦理框架,指出环境伦理必须与个体的反思联系起来,并制定负有责任的社会政策与计划。 威斯林德(P. Aarne Vesilind)则提出工程师应当如何在增加人类财富与破坏环境之间求得某种平衡?在面对潜在的环境问题时,在什么情况下工程师应当为客户保密呢? 哈里斯等人从工程规范与环境出发,分析了职业工程对于环境的责任范围,提出了两个折中的建议。同时专业伦理规范也开始加入保护环境责任的内容,如美国土木工程师协会的伦理规范,就既要求提高人类的福利,还要求保护环境。但是环境问题依然是任重而道远。第三,对于工程应用的国际问题关注。跨国公司对于技术转移所产生的国际权利问题,以及武器发展与保护工业问题,这些都是军事领域与和平研究的道德问题。[27]而国际工程职业标准也涉及到超文化规范,跨文化规范在工程活动应用中也产生了伦理问题,如贿赂、索贿、打点、礼物等现象。同时由于工程技术的应用,也产生了世界性贫困等问题,但依然被人们所忽视。

求英文翻译中国航天技术发展历程

Rocket can carry and launch a satellite into space, and satellites can also safely return, these two results had been achieved for the manned space flight lay a technological foundation. In addition to the obvious economic benefits, the development of manned space flight involving astronomy, medicine, aerodynamics, dozens of subject areas. It will reflect the maturity of a country"s overall technological level is related to a country"s life and death in the space age. Manned space flight has been 42 years of human history (in 1961 the former Soviet Union to achieve the world"s first manned space flight), China"s manned space program was officially launched in 1992, took only seven years after the breakthrough in the space on the highest technical. At 6:30:07 on November 20, 1999, China"s first pilot a spaceship "Shenzhou I" successful initial public offering, China became the United States and Russia have after the world"s first three manned space technology countries. Upon completion of 21 hours of space scientific experiments, after at 3:41 on the 21st successful landing. "Shenzhou" spacecraft successfully launched and recovered to become another milestone in China"s space history. The success of the date of November 21, 1999, from the days of the end of this year, only one month and 9 days. In the seven-year period the number of the calendar day countdown to the astronauts live, many people just want to sleep on the Haohaodeshui. But even such a simple desire to right a lot of people speaking, but also an elusive luxury. In the new war drums, the "Shenzhou II" again underway. Crane was riding rumbled advance of Chinese astronauts in space to be ideal for a nation to race against time! Soon, the second ship spaceship "Shenzhou II" is created, its performance than the "Shenzhou I" more advanced life-support systems to ensure safety and maintain the equipment installation is also much stronger. January 10, 2001 at the Jiuquan Satellite Launch Center, flying seven days after the successful return to the ground. This is China"s first unmanned spacecraft. Spacecraft on a micro-gravity environment of space life sciences, space materials, space astronomy and physics experiments and other fields, all kinds of instruments and equipment performance, stability, job properly, has made large amounts of data. With the "Shenzhou" spacecraft on the 1st than the "Shenzhou II" spacecraft system architecture has a new expansion, technical performance has been enhanced, the spacecraft and manned spacecraft technology, the state basically the same. Followed by Shenzhou III spacecraft on March 25, 2002 launch. Spacecraft carrying human metabolic simulator, anthropomorphic dummies physiological signal equipment and body can be quantitatively simulate the astronauts breathing and blood circulation of the important physiological parameters. "Shenzhou" on the 3rd orbital module left in space orbit more than 180 days, successfully conducted a series of space science experiments. December 30, 2002, the "Shenzhou" spacecraft lifted off on the 4th is China"s manned space flight last rehearsal is the manned space program since the implementation of technical requirements for the highest, most all the tested systems, the most difficult one flight test We still face the most severe since the launch of the manned space flight test: a rare cold launch ever, the minimum temperature close to -30 ℃, low-temperature launch conditions over the past 10 ℃, and the launch of the spacecraft has now entered an irreversible state. "Shenzhou" spacecraft on the 4th the last successful launch marked China"s manned space project that no one state has withstood the most comprehensive flight test trials, creating the history of China"s space launch a new record low temperature, but also created the world"s aerospace history Rocket the miracle of low-temperature firing. Academician Liang Sili Chinese space experts said that although the "Shenzhou" spacecraft, launch Bimei, Russia later, but my spaceship from a higher development. "Shenzhou" spacecraft, the orbital module to conduct both stay in orbit for earth observations, but also as a future space rendezvous and docking of an aircraft, is the next space shuttle transportation excellent tool. October 6, the Associated Press released to the world the message: In the upcoming launch of manned spacecraft ago, China announced as early as three years, the lunar satellite into lunar orbit. Code-named "Chang"e Project" of Chinese lunar exploration program started in March of this year, is proceeding smoothly. In another development, if all goes well, 10 years later, the moon will occur the Chinese presence. AD October 15, 2003 was an unusual day, 9 hours, Yang Liwei"s "Shenzhou" V spacecraft in the deafening roar shook the ground in the sky. On this day people around the world have seen the Chinese people fly in space, Yang Liwei. From that day onwards, Haomiao waving the banner of the universe to begin with the Chinese flag. That ship carrying the whole nation of hope "magic boat" gash in China a new space age. AD October 16, 2003 morning 6:23, China"s "Shenzhou V" spaceship take-off 21 hours later, successfully landed in the open grasslands of Inner Mongolia. No footprints of the Chinese people in space history ends here. Flying from the Dunhuang mural came out.我没有神7的材料有的话给我吧。(这是到神5的)鄙视那些复制的人~~~~~

can you imagine what the great wall is like____ from the shuttle in space? A to see B

Can you imagine what the great wall is like____ from the shuttle in space?你能想象出从太空飞船上看长城什么样子吗?选B seen,过去分词作状语,。(seen 为过去分词作状语,表"被看",由语境可知,它的逻辑主语必须是长城,而不是"你"。) 如果我还原一下从句你就明白了:Seen from the shuttle in space,the Great wall is very beautiful.提问beautiful就是:What"s the Great Wall like seen from the shuttle in space?然后再把上面这个句子放到Can you imagine ......... ?就是你看到的句子了。再看下面的例子:Seen from the top of the hill,the city looks more beautiful to us. 从山顶看城市,城市显得更漂亮。(seen 为过去分词作状语,表"被看",由语境可知,它的逻辑主语必须是城市,而不是"我们",因为"我们"应主动看城市。) 上面是我的看法,希望对你有帮助,满意请采纳
