24、軍事戰(zhàn)略和其他很多學科都有廣泛的應用。zero-sum games (Para.1)零和博弈（非合作博弈），一人或一方得益必然引起另一人或另一方損失的局面。John von Neumann (Para.2)約翰馮諾依曼（1903-1957），匈牙利裔美國數(shù)學家，普林斯頓大學和普林斯頓高等研究所教授，曾任研制原子彈的顧問，并參加研制計算機，被稱為計算機之父，1954年成為美國原子能委員會委員。作為20世紀最杰出的數(shù)學家之一，他在數(shù)理邏輯、測度論、格倫和連續(xù)幾何學方面都有開創(chuàng)性的成果；在博弈論和控制論、力學、經(jīng)濟學和計算機研制等領(lǐng)域做出了杰出的貢獻。他同莫根施特恩合作，寫出博弈論和經(jīng)濟行為一書，這

25、是博弈論中的經(jīng)典著作，使他成為數(shù)理經(jīng)濟學的奠基人之一。tic-tac-toe (Para.6)井字棋，一種益智游戲。兩人輪流在一井字形方格內(nèi)畫“x”和“o”，以先列成一行者得勝。John Nash (Para.8)約翰納什，1928年6月13日出生在美國西弗吉尼亞州，1950年獲得美國普林斯頓高等研究院數(shù)學博士學位，1951年至1959年在麻省理工學院（MIT）數(shù)學中心任職。現(xiàn)任普林斯頓大學數(shù)學系教授，美國科學院院士。國際公認的博弈論創(chuàng)始人之一，是繼馮諾依曼之后最偉大的博弈論大師之一。納什主要在純數(shù)學領(lǐng)域從事學術(shù)研究，其數(shù)學成就十分突出。然而，他對經(jīng)濟學研究產(chǎn)生重大影響的還是在博弈論上，可以概

26、括為兩點：第一，納什明確區(qū)分了合作對策與非合作對策，并指出，在合作對策中可以達成有約束力的協(xié)議，而在非合作對策中，則達不到；第二，對于兩人以上的非合作對策，可能出現(xiàn)什么樣的結(jié)果，納什提出了分析方法，這一方法可以用“納什均衡”來稱謂。后來對博弈論的許多討論，都是建立在納什均衡這一概念之上的，他提出的著名的納什均衡的概念在非合作博弈理論中起著核心的作用。后續(xù)的研究者對博弈論的貢獻，都是建立在這一概念之上的。由于納什均衡的提出和不斷完善為博弈論廣泛應用于經(jīng)濟學、管理學、社會學、政治學、軍事科學等領(lǐng)域奠定了堅實的理論基礎，1994年納什因此獲得諾貝爾獎經(jīng)濟學獎。Nash equilibrium (Pa

27、ra.8)納什均衡，又稱為非合作博弈均衡，是博弈論的一個重要術(shù)語，以約翰納什命名。在一個博弈過程中，無論對方的策略選擇如何，當事人一方都會選擇某個確定的策略，則該策略被稱作支配性策略。如果兩個博弈的當事人的策略組合分別構(gòu)成各自的支配性策略，那么這個組合就被定義為納什均衡。一個策略組合被稱為納什均衡，當每個博弈者的均衡策略都是為了達到自己期望收益的最大值，與此同時，其他所有博弈者也遵循這樣的策略。prisoners dilemma (Para.10)囚徒困境，博弈論的經(jīng)典案例。囚徒困境是博弈論的非零和博弈中具代表性的例子，反映個人最佳選擇并非團體最佳選擇。雖然困境本身只屬模型性質(zhì)，但現(xiàn)實中的價格

28、競爭、環(huán)境保護等方面，也會頻繁出現(xiàn)類似情況。單次發(fā)生的囚徒困境，和多次重復的囚徒困境結(jié)果不會一樣。在重復的囚徒困境中，博弈被反復地進行。因而每個參與者都有機會去“懲罰”另一個參與者前一回合的不合作行為。這時，合作可能會作為均衡的結(jié)果出現(xiàn)。欺騙的動機這時可能被受到懲罰的威脅所克服，從而可能導向一個較好的、合作的結(jié)果。Cortes (Para.16)赫爾南多科爾蒂斯，16世紀殖民時代活躍在中南美洲的西班牙殖民者，以摧毀阿茲特克（Aztec）古文明，并在墨西哥建立西班牙殖民地而聞名。strategy of brinkmanship (Para.17)邊緣化策略。邊緣化策略指在國際政治和外交活動中，故

29、意使局勢變得無法控制的策略，正是由于局勢的無法收拾可能令其他對手難以接受，從而迫使對手做出妥協(xié)。Thomas Schelling (Para.17)托馬斯謝林（1921-），2005年諾貝爾經(jīng)濟學獎獲得者，1951年獲得哈佛大學經(jīng)濟學博士學位，曾在美國哈佛大學肯尼迪學院執(zhí)教20年，擔任政治經(jīng)濟學教授，并獲得退休名譽教授的稱號，1991年被選為美國經(jīng)濟學協(xié)會會長，現(xiàn)在美國馬里蘭大學公共政策學院和經(jīng)濟系擔任教授，并獲得退休名譽教授稱號。他教授的課程除包括經(jīng)濟學理論外，還涉及外交、國家安全、核戰(zhàn)略以及軍控等多方面。謝林重要的理論著作包括沖突戰(zhàn)略、武器與影響等，其中前者是相關(guān)領(lǐng)域中最具有開創(chuàng)性的理論著

59、roduce）。合成之后的復合詞往往無法在詞典中直接查到詞義，因此需要先借助詞典確定單個詞語的含義，然后結(jié)合復合詞的構(gòu)成特點來理解其含義。復合名詞的構(gòu)成：名詞+名詞 (e.g. 見P47，下同。)形容詞+名詞分詞+名詞名詞+動名詞形容詞+動名詞多詞復合名詞 （由兩個以上的修飾詞加上中心名詞構(gòu)成，如industrial distribution equipment 工業(yè)配電裝置。）復合形容詞的構(gòu)成：名詞/形容詞/副詞+形容詞 (e.g. 見P47，下同。)形容詞/數(shù)詞+名詞名詞/形容詞/數(shù)詞+名詞-ed名詞/代詞/形容詞/副詞+分詞多詞復合形容詞 （如out-of-date過時的）復合動詞的構(gòu)成

60、：動詞+介詞/連詞+動詞 （如point-and-click點擊）動詞+介詞 （即將一個動詞詞組中的動詞與介詞用連詞符號連接為一個詞，如sign-on登錄。）形容詞+動詞 （如mass-produce成批生產(chǎn)）Skills for Translation 科技術(shù)語 通常專業(yè)科技術(shù)語會有約定俗成的依法，或有全國科技名詞審定委員會來推薦譯名。常見的術(shù)語譯法分為以下幾類：意譯(即通過對原詞的仔細推敲和理解，準確地譯出其表達的科學概念。)音譯(即根據(jù)英語單詞的發(fā)音譯成讀音與原詞大致相同的中文。通常表示計量單位的詞和新近發(fā)明的科技材料或產(chǎn)品采用這種譯法。）意音結(jié)合譯 (即在音譯之后加上一個表示類別的詞，
