    日本即將測試太空電梯 希望2050年正式動工

    進入太空需要對抗地球引力,需要昂貴的火箭和大量的燃料,因此科幻小說家一直有一種想像:連接地球和太空的電梯。現在日本工程師即將開始做小規模測試。 科學警報(science alert)報導,日本靜岡大學工程學院團隊將在9月11日進行一種規模很小,但是很重要的實驗,兩個長寬只有10公分的小立方衛星,以10公尺的鋼纜相連接,並且會有一座小電梯,在衛星中間的鋼纜來回移動,以測試太空電梯的可行性。 靜岡大學的團隊成員表示:「這將是世界第一次太空中電梯運動的測試實驗。」 太空電梯的發想是俄國太空理論專家康斯坦丁.齊奧爾科夫斯基(Konstantin Tsiolkovsky)提出的,他是在1895年看到巴黎艾菲爾鐵塔後,感受中間的電梯後,就提出連接太空與地球的電梯。自他以後,這項技術已經多次出現在各種科幻小說當中。 實施太空電梯所涉及的技術挑戰非常巨大,首先它需要由足夠輕的材料構成高塔,以免被自身重量壓垮,同時還需要具備足夠的強度,以承受由因離心力作用造成的的張力,以保持電梯;第三,它還必須承受來自地球、太陽和月亮的重力,以及地球本身的氣候環境(比如強風)。 又輕又強韌的奈米碳管技術一直被認為是太空電梯的好材料,但目前還不具備大量製造奈米碳管的技術,而整座太空梯電,至少需要生產96000公里的奈米碳管纜繩。 然而,日本的研究團隊認為,思考材料的強度之前,應該要先證明太空電梯理論是否可行,因此靜岡大學才會先進行這場實驗,他們要瞭解,在太空環境中,電梯能否成功運行,還是會受到電梯行動時的扭力給影響。 靜岡大學工程師石川洋司(Yoji Ishikawa)說:「從理論上講,太空電梯非常合理,我相信未來人類前往太空,就是搭電梯一樣簡單。」 日本建築公司大林組已經宣示,只要太空電梯的原理被證明可行,他們就會希望在2050年時,將太空電梯給完成並投入運營。

    世界之窗-「麥肯錫30秒電梯理論」學英文

     「McKinsey30秒電梯理論」緣於McKinsey麥肯錫公司一次沉痛的教訓。  McKinsey曾經為一家重要的大客戶做諮詢。諮詢結束前,McKinsey的專案負責人在電梯裡遇見了對方的董事長,該董事長問McKinsey的專案負責人:「你說一下現在的結果吧!」專案負責人沒有準備,而且即使有準備,也無法在電梯從30層到1層的30秒內把結果說清楚。於是McKinsey失去了這個重要客戶。  此後McKinsey要求公司員工要在最短的時間內把結果表達清楚,簡報要直奔主題、切中要害。大部份人只能記住一二三點,所以你的重點不能超過3項。這就是如今在企業界流傳甚廣的「30秒鐘電梯理論」或稱「電梯演講」。  「McKinsey30秒電梯理論」不只是行銷業務的利器,它也是商業人士學英文最佳的策略。  ●30秒說服創投為什麼要投資你?  ●30秒說服消費者買你的產品?  ●30秒說服企業老闆應該要晉用你?  ……  你只有30秒,而且是"in English",假如你還做不到,請你仔細讀以下這一篇文章,商業策略和英文的難題,畢其功於一役!  The Elevator Test  Know your solution (or your product of business) so thoroughly that you can explain it clearly and precisely to your client (or customer or investor) in 30 seconds. If you can do that, then you understand what you're doing well enough to sell your solution.  Imagine it's time for that big, end of engagement presentation. You and your team have been up until 2 A.m. putting together your report, making sure that every I has been dotted and every T has been crossed. You're all wearing your best suits and trying to look on the ball. The senior executives of your Fortune 50 client, anxious to hear McKinsey's world of wisdom, are taking their places around the boardroom table on the top floor of the corporate skyscraper. The CEO strides into the room and says, "Sorry, folks. I can't stay. We have a crisis and I have to go meet with our lawyers." Then he turns to you and says "Why don't you ride down in the elevator with me and tell me what you've found out?" The ride will take about 30 seconds. In that time, can you sell him your solution? That's the elevator test.  Many companies use the elevator test because it's an excellent way of making sure that their executives' time gets used efficiently. Procter Gamble tells its managers to write one page memos. A Hollywood producer will tell a screen writer to "give me that bullet" on a new script; if, after 30 seconds, the producers likes what he's heard, the writer will get a chance to talk further, and maybe make a sale. Jason Klein instituted the elevator test when he took over as president of Field Stream:  "My sales force could not explain the magazine to customers. Our advertisement space was shrinking. Then I trained my entire sales force on the elevator test. I challenged them to explain the magazine to me in 30 seconds. It became a valuable tool for them, and our ad base has grown every year."  How do you encapsulate six months' work in 30 seconds? Start with the issues that your team addressed. The client wants to know the recommendations for each issue and the payoff. If you have a lot of recommendations, stick to the three most important - the ones with the biggest payoffs. Don't worry about the supporting data; you can talk about that when you have more time.  For example, your analysis shows that a manufacturing client can't sell enough widgets because its sales force is organized by territory when it should be organized by buyer category.  Notes:  1. every I has been dotted and every T has been crossed.  這用法源於一個片語dot the i's and cross the t's,意思是對細節一絲不茍。dot在此是動詞,表「在……上打圓點」。cross也是動詞,表「畫橫線」。dot the i's and cross the t's字面意思是「寫i時要畫一點,寫t時要畫一橫」,引申為「對細節一絲不茍」之意。片語中的the也可用所有格代替。  例:Dot the i's and cross the t's to make sure nothing is wrong.(做事要仔細謹慎,以確保一切正確無誤。)  2. pay off 用法  (1) 取得成功;得到好結果  Two years of business school really paid off.(在商學院就讀兩年真是值回票價。)  Did his plan pay off? (他的計畫成功了嗎?)  (2) 清償債務  We will have more money to spend after we pay off our mortgage.(在付清貸款後,我們會有更多錢花。)  He has paid off all his debts.(他已還清了所有的債務。)  (3) 付清薪資後解雇  The company has paid off some redundant employees.(公司在發放薪資後解雇了一些冗員。)  讓你在最短的時間裡,找到最有效的商業英語對話結構。體驗30- second speech:「McKinsey 30秒電梯理論」英語學習法。請上網:www.core-coner.com.
