Ⅱ 愛迪生有哪些故事
「世界發明大王」愛迪生的一生共有約兩千項創造發明,如我們眾所周知的留聲機、電燈、電話、電報、電影等等,當然他的一生中也不乏許多小的發現或發明同樣改變了我們的生活,比如說「復印機」:起初,愛迪生發明了石蠟紙,只是普遍運用於食品如糖果的包裝材料上,後來他嘗試在蠟紙上刻出文字輪廓,形成一張石蠟刻字紙版,在紙版下墊上白紙,再用墨水的滾輪從刻字的石蠟紙上滾一滾,奇妙的事就發生了——白紙上出現了清楚的字跡。有了這個發現,愛迪生又經過多次的改良、試驗,1876年,愛迪生開始量產他發明的復印機,一下子,機關,團體,學校,企事業單位,都採用了這種機器。當然,現在我們早已不再使用那樣「陳舊」的設備,但是今天我們能夠使用到如此高科技的復印設備,正是源於愛迪生的一個小小發現;再比如,我們當今廣泛使用於汽車及建築玻璃等方面的的「太陽膜」,也是源於愛迪生在研發電影技術時的一個偶然發現:1888年,愛迪生發明留聲機後,他將注意力轉放到了研發電影上,他說「我正在實驗一種專供眼睛用的器具,就像留聲機是專供耳朵用的器具」,而他的實驗結果就是電影攝影機 (Kinetograph)及電影視鏡(Kinetoscope:通過窺視孔,在電燈光照明下,放大觀看幻燈片的裝置)。他拍下一系列照片,將它們迅速地、連續地放映到幕布上,產生出運動的幻覺,而這些照片的載體就是我們眾所周知的「膠片」,這時他發現了一個非常有趣的現象,那就是同樣受電燈強光、強熱照射的膠片,顏色越深的膠片就越能阻隔夠吸收電燈所散發出的熱量,於是愛迪生把這個發現隨手記在了自己的工作筆記中——恰恰就是這個偶然的發現,奠定了早期太陽膜的理論基礎。時至今日,我們眼前琳琅滿目的各種太陽膜仍然都在使用與膠片相同的主要原料Pet(聚酯塑料的一種)作為基礎材料,鑒定太陽膜質量優劣的方法也仍然是採用高發熱燈泡照射來比對隔熱率和透光率。無論是採用那一種工藝生產的太陽膜,它的基本的原理都一樣,那就是我們偉大的「世界發明大王」隨手記在筆記本上的那一段話。在愛迪生的一生中,諸如這樣的小故事不勝枚舉,我們不禁感嘆,愛迪生的一生為人類的文明和進步作出了多麼巨大的貢獻!
Ⅲ 描寫愛迪生外貌的語句段落摘抄
The Life of Thomas Edison
"Genius is 1% inspiration and 99% perspiration."
Thomas Edison
Edison was an inventor known for his influence,his intelligence and,most importantly,his perseverance.During his lifetime more than a thousand American patents were granted on work of his own or of teams under his supervision.Three of his inventionsthe phonograph,a practical incandescent light and electric system,and a moving picture camerahelped found giant instries that were to change the life and leisure of the world.In other areas Edison managed to affect over twenty instries including the military,medical fields (with his fluoroscope),the stock market and mining.Following is a short biography and a timeline of his greatest accomplishments.
Inspiring Childhood.Thomas Edison,the youngest of seven children,was born in Milan,Ohio,on February 11,1847,to Samuel and Nancy Edison.Home schooled and an avid reader,Edison began his scientific experiments at the age of ten when he built a laboratory in the basement of his house stocked with chemicals he either bought or found in the town mp.Edison's early experimentation was almost stopped when his mother became tired of bad odors and fumes filling the house.
The Tramp Telegrapher.Edison left the laboratory behind for a career as a "candy butcher" on the Grand Trunk Railway in 1859,selling candy,dried fruit,snacks and newspapers.Three years later he made history when he began to publish his own newspaper,the Weekly Herald,aboard the train.The first newspaper to be published aboard a moving train,the Weekly Herald,was printed on a secondhand printing press Edison set up in the baggage car of the train.In 1863,he began his first career as a "tramp telegrapher," going from place to place including Ontario,Cincinatti and Nashville,offering his skills as a telegrapher.He finally settled in Boston,working the New York wire for Western Union.
Learning to be Practical.It was in Boston that Edison began experimenting in a more professional way than ever before,first studying Michael Farady's writings on electricity.His first patent in 1868,was a vote recorder which sped up,through electrical messages,the counting of votes for assemblies and meetings.Finding no buyer for his first invention,he formed a policy to never attempt to invent anything unless he was sure there was a commercial demand for it.His next invention demonstrated his commitment to this ideal,a stock ticker that would bring brokers Wall Street quotations more quickly.
Pure Science Experiments.With two notable exceptions,Edison rarely dabbled in anything other than the practical application of principles and scientific theories.In 1875,while working on a theory of electromagnets and telegraphy,Edison discovered a type of energy between electromagnetism and heat and light.Named "etheric force," this discovery revealed the existence of the electromagnetic wave and prompted the invention of the radio in the 1890's.The second time was with his discovery of the "Edison Effect," the basis for the whole field of electronics.Edison discovered that a valve could be created for an electronic current by inserting a metal plate within the filament of an electric light bulb.
The Menlo Park Laboratory.Edison's laboratory at Menlo Park,New Jersey became the first of its kind,the original organized technical research laboratory,with its research "team." Inventions that came out of this new research include the mimeograph machine,the phonograph,the light bulb,and many others.
First of the Great Inventions The phonograph,the light bulb and the motion picture camera have long been considered Edison's greatest inventions.The phonograph,the first of these inventions,was developed after Edison began work on improving Alexander Graham Bell's telephone.Edison believed that the phonograph (which has changed very little from its original design) was his greatest invention.Interestingly enough,the phonograph is the only invention for which Edison can claim sole ownership.
Early Movie Business.Other inventors were experimenting with the motion-picture camera when,in 1891,Edison came up with the practical movie camera,or the Kinetograph ("moving writing"),and a projector,the Kinetoscope ("moving view"),to show his movies.The first movie studio built in 1893,was his Black Maria at West Orange,New Jersey.Edison,who had been working unsuccessfully on "talkies" by combining the phonograph and the camera,left the motion picture business when the instry started to turn away from the ecational purpose he saw for it and towards entertainment.Edison was quoted as saying " A good many people seemed to wonder why I did so [quit the movie business] maybe they still wonder.But the answer is simple enough.I was an inventor an experimenter.I wasn't a theatrical procer.And I had no ambitions to become one." Incidentally,movie audiences would not hear the human voice on film until 1927 with Al Jolson's The Jazz Singer.
The Light Bulb.Edison is quoted as saying it would take a matter of a few weeks to invent the bulb.In reality,it would take him almost two years of failed attempts,new discoveries and prototypes before he would find success.It is said he tried over 6,000 different carbonized plant fibers,looking for a carbon filament for his light bulb.By concentrating and inventing a whole lighting system rather than just a single light bulb,Edison succeeded where others had failed.Edison chose to look at the big picture and created a lighting system including wiring,plugs,connectors,etc.,to operate more than one light bulb at once.Fighting other inventors in courts from England to America,Edison struggled for years to claim his rightful title of inventor of the light bulb,possibly his most popular invention.
Military Inventions of the War Years!During World War I,Edison became the head of the Naval Consulting Board,and for three years he worked on inventions to help the U.S.Navy.Working on antisubmarine tactics,Edison worked to combat the Germans in the Atlantic wars.His inventions included devices that could detect torpedoes as soon as they were fired,a loud-speaking telephone so that a conversation could be carried on in the middle of a battle,and a glare eliminator to make it possible for ships to see periscopes with the bright sunlight shining on the water.
Medical Breakthroughs In 1896,Edison invented the practical fluoroscope,a machine which included a screen made out of tungstate of calcium on which you view X-rays.Edison refused to take a patent out on his fluoroscope because he wanted to see it in use,helping people,immediately.The fluoroscope enabled surgeons to perform the first x-ray operation in the United States.
The Perseverant Inventor One of Edison's most famous qualities was his perseverance.While working on the nickel/iron storage battery,he performed 10,296 experiments.Throughout his inventing career,Edison followed almost every unsuccessful venture with a successful idea.He stuck to his creed of working on only useful and wanted inventions and changed the world with his drive for success.When Edison died October 18,at his home in West Orange,New Jersey,he left behind a legacy of breakthroughs in technology and science.

托馬斯·愛迪生的生活
「天才是1%的靈感和99%的汗水。」
托馬斯·愛迪生
愛迪生是一個發明家以他的影響力,他的智慧,最重要的是,他的毅力。在他有生之年超過一千項美國專利被授予他自己的工作或團隊在他的監督下。他的三個inventionsthe留聲機,一個實際的白熾燈和電氣系統,移動圖片camerahelped發現巨大的產業,改變世界的生活和休閑。在其他領域愛迪生成功地影響超過20個產業包括軍事、醫學領域(與他的螢光屏),股票市場和礦業。下面是一個簡短的傳記,他最大的成就的時間表。
鼓舞人心的童年。托馬斯·愛迪生,七個孩子中最小的一個,出生在米蘭,俄亥俄州,2月11日,1847年,塞繆爾和南希·愛迪生。家庭教育和一個狂熱的讀者,愛迪生開始了他的科學實驗十歲時,他在他的房子的地下室建了一個實驗室備有化學品他買了或發現鎮上轉儲。愛迪生的早期實驗幾乎停止當他的母親成為累壞氣味和煙霧填滿。
流浪漢報務員。愛迪生事業留下實驗室作為「糖果屠夫」1859年大幹線鐵路,賣糖果、乾果,零食和報紙。三年後,他創造了歷史,他開始發表自己的報紙,每周的先驅,乘坐火車。的第一份報紙上發表一個移動的火車,每周的先驅,是印在一套二手印刷機愛迪生在火車的行李車。1863年,他開始了他的第一個職業是「流浪漢報務員,」從一個地方到另一個地方包括安大略省Cincinatti和納什維爾,提供他的技能作為一個報務員。最後他停在波士頓,紐約線為西部聯合電報公司工作。
學習實踐。在波士頓,愛迪生開始嘗試以更專業的方式比以往任何時候都要多,首先學習邁克爾Farady電力的著作。他的第一個專利,1868年是加快的投票記錄,通過電子信息,選票計數的程序集和會議。沒有找到買家對他的第一個發明之後,他成立了一個政策從未試圖創造什麼,除非他肯定有一個商業需求。他的下一個發明對此做出了理想,華爾街股票,將代理報價更快。
純科學實驗。有兩個值得注意的例外,愛迪生很少涉足除了原則和科學理論的實際應用。1875年,工作時電磁鐵理論和電報,愛迪生發現的一種電磁之間的���量,光和熱。被稱為「以太力量」,這個發現揭示了電磁波的存在,促使1890年無線電的發明。第二次是他發現的「愛迪生效應」,整個電子產品領域的基礎。愛迪生發現閥可以創建一個電流通過插入金屬板在電燈泡的燈絲。
門洛帕克實驗室。新澤西愛迪生的實驗室門洛帕克成為了首次,原始組織技術研究實驗室,研究」團隊。「發明這項新研究出來的包括油印機、留聲機、燈泡,和許多其他人。
第一個偉大發明的留聲機,燈泡和電影攝影機一直被認為是愛迪生最偉大的發明。這些發明的留聲機,第一個發達後,愛迪生開始提高亞歷山大·格雷厄姆·貝爾的電話。愛迪生認為留聲機(從原來的變化很少設計)是他最偉大的發明。有趣的是,愛迪生的留聲機是唯一的發明可以聲稱的獨家所有權。
早期的電影產業。其他發明家試驗時的電影攝影機,1891年,愛迪生想出了實用的電影攝影機,或者電影攝影機(「寫作」),和一個投影儀,電影放映機(「視圖」),以顯示他的電影。第一個電影製片廠建於1893年,是他在西奧蘭治的囚車,新澤西州。愛迪生曾工作失敗「有聲電影」結合留聲機和相機,離開了電影業務在行業開始遠離他看到教育目的和對娛樂。愛迪生說「很多人似乎不知道為什麼我這樣做(退出電影行業)也許他們還不知道。但答案很簡單。我是一個發明家實驗者。我不是一個戲劇製作人。和我沒有野心成為一個。「順便說一句,電影觀眾不會聽到人的聲音在電影直到1927年與男星艾爾的爵士歌手。
燈泡。愛迪生援引需要幾周的發明燈泡。在現實中,這幾乎將他兩年的失敗的嘗試,新發現和原型之前他會成功。據說他試著超過6000種不同的炭化植物纖維,尋找碳絲燈泡。通過集中和發明一個整體照明系統而不是一個燈泡,愛迪生已經在別人失敗的地方獲得了成功。愛迪生選擇看大局,創建了一個照明系統包括電線、插頭、連接器等。,操作多個燈泡。戰斗在法院從英國到美國其他發明家,愛迪生掙扎多年的發明者聲稱他的合法的燈泡,可能是他最受歡迎的發明。
戰爭年代軍隊的發明!第一次世界大戰期間,愛迪生成為海軍咨詢委員會的負責人,和三年他發明幫助美國海軍。在反潛戰術,愛迪生在大西洋戰爭抗擊德國人工作。他的發明包括設備能夠檢測魚雷就被解僱,loud-speaking電話,談話可能進行的戰斗,和眩光器使船隻看到潛望鏡和明亮的陽光照耀在水面上。
醫學突破1896年,愛迪生發明了實用的螢光屏,一台機器包括屏幕的鎢酸鈣,查看x射線。愛迪生拒絕接受一個專利在他的螢光屏,因為他想看到它在使用,幫助人們,立即。熒光鏡使外科醫生執行第一個x射線操作在美國。
鍥而不舍的發明家愛迪生最著名的品質之一是他的毅力。鎳/鐵蓄電池工作時,他於10296年執行實驗。愛迪生在發明生涯,之後幾乎所有的失敗的風險,一個成功的想法。他堅持他的信仰只工作有用的,想要的發明,改變了世界追求成功的動力。當愛迪生10月18日去世時,在西奧蘭治的家中,新澤西,他留下的遺產突破技術和科學,
很辛苦的,望採納

Ⅳ 特斯拉完成拆股 股價延續升勢
財經網汽車訊?完成拆股後,特斯拉股價延續了之前的強勁走勢,每股現價接近500美元。
當地時間8月31日,特斯拉迎來拆股後首個交易日,截至收盤,特斯拉股價上漲12.57%,報498.32美元。
此前在8月11日,特斯拉提交了拆股計劃,宣布對股票按「1拆5」的比例進行拆分,8月28日收盤後,特斯拉投資者所持的每一股股票變成五股,經分割調整後的股票在8月31日如期交易。
拆股又稱「分割」,通常指在不影響股東權益的情況下,將面額較高的股票拆分成面額較低的股票。就在特斯拉宣布拆股不久前,蘋果宣布一比四的拆股計劃,有不少投資者因此認為,美股「拆股潮」即將到來。實際上,近年來美股的走勢的確是一路走高,諸多被看好的科技公司股價和市值也一路飆升,如何使散戶投資者的購買力跟上高企的股價,成為拆股的直接動力。
在周期性股市震盪的美股,史上曾出現過多次拆股和合股熱潮。2008年金融危機席捲全球,許多企業股價大幅下挫,包括時代華納、花旗集團在內的多家上市企業紛紛通過合並股票的手段提高股價,避免被摘牌。2009年,從金融危機震中走出來的美股開始逐步復甦,標普500股指觸及666.79的盤中低位後一路反彈,截至今年8月底,標普500指數首次站上3500點,納斯達克指數也創新高。
特斯拉正是乘上了這一波浪潮,一年內漲幅達500%。盡管高股價體現著企業經營的穩定性和強勁業績,但高漲的價格無疑不利於股票流通。美國德美利證券(TDAmeritrade)首席投資策略分析師JJKinahan在特斯拉拆股交易首日表示,事實證明,當前特斯拉交易量增加了五倍,進行交易的賬戶數量增加了七倍,這說明拆股後,更多的普通投資者能負擔得起特斯拉股價,一般來說,散戶投資者往往最關注資產管理,單只股票價格降低後,購買100股對於散戶來說更容易。
第一財經援引星展銀行(中國)投資策略總監鄧志堅報道稱,通常一個企業進行拆股,讓更多看好企業的投資者能入場,這會被視為利好。同時,他還認為,從股東的實際利益出發,股份分拆,現有股東股權不變,權益不變,獲得的派息不變,對原有股東沒有影響。
盡管叫好聲一片,仍有部分投資人對特斯拉近一年來的走勢持謹慎態度。投資咨詢機構DouglasC.Lane合夥人SaratSethi表示,從同一塊蛋糕中分出更多塊蛋糕的想法令人感到擔憂,尤其是允許更多散戶投資者進場的時候,拆分股票引起股價短期內走高也正是基於此;市場的彈性在於泡沫的適時釋放,散戶純粹追逐拆分股的行為不利於市場健康。
家族財富管理機構OmegaFamilyOffice的董事長兼總裁LeonCooperman表示,拆分不會創造價值,把五美元的鈔票換成五張一美元,不會增加財富總額,這是不爭的事實。或許對於特斯拉而言,如何為翻五番的股價走勢提供可持續的業績支撐,是一個更為長遠的命題。
公開資料顯示,今年第二季度特斯拉總營收為60.36億美元,按公認會計准則營業利潤為3.27億美元,營業利潤率為5.4%,凈利潤為1.04億美元,這是特斯拉連續第四個季度實現盈利。財報中種種跡象表明,特斯拉將持續提高產能、興建工廠、擴大市場。在資本市場上,特斯拉已坐上全球第一大市值車企的寶座,全球業績方面,中美兩大市場的銷量王座似乎也已坐穩。
ArkInvest分析師TashKiney表示,將維持特斯拉2024年7000美元的目標價。ArkInvest創立於2014年,目前管理資金約50億美元,一直將特斯拉作為最大持倉。
值得注意的是,特斯拉在中美市場異軍突起的同時,一眾傳統汽車巨頭也蓄勢待發。目前,雷諾旗下純電動產品Zoe在上半年一舉超越特斯拉,成為歐洲最暢銷的新能源汽車產品。被市場認為最有望扳動特斯拉地位的大眾ID.4將於9月開啟預售,保時捷推出全新純電動品牌Taycan、奧迪推出純電SUV品牌e-tron,以及各大車企先後推出的電動化戰略,這意味著市場競爭將會加劇,特斯拉能否在股價高漲的同時實現業績的大幅提升,或將成為維持其高估值的一個關鍵因素。
