機(jī)械工程專業(yè)英語 第二課翻譯的基本方法 詞義的選擇Skills of Translation acceptation selection 要提高譯文的質(zhì)量， 使譯文達(dá)到“準(zhǔn)確”、“簡練”、“通順”這三個(gè)標(biāo)準(zhǔn)，就必須學(xué)習(xí)翻譯技巧。翻譯的技巧就是在翻譯過程中用詞造句的處理方法。如詞的選擇、詞義的引伸、增詞、減詞、轉(zhuǎn)換詞類、改變句子結(jié)構(gòu)、變更詞序和改換譯法等。一、詞義的選擇 詞義的選擇實(shí)際就是英語詞在特定句子中的詞義的判斷和確定。詞在特定句子中的確切含義，在很大程度上取決于上下文。也就是說，詞的含義必須根據(jù)詞在句子中的作用詞的搭配習(xí)慣以及詞的應(yīng)用場合予以判斷和確定。一般可從下列幾個(gè)方面去判斷。 翻譯的基本方法 詞義的選擇Skills of Translation acceptation selection1、根據(jù)詞類判斷詞義英語中，有些詞用作不同的詞類時(shí)，其詞義有時(shí)是不相同的。因此我們可根據(jù)詞類來確定詞義。l Every metal part is of great importance to machines.每一個(gè)金屬部件對(duì)機(jī)器都是很重要的。(n)l Aluminum machines faster than other metals.鋁加工起來比其它金屬快。(v)l icroprocessors monitor tyre wear and brake power on cars. 微機(jī)檢測汽車輪胎的耐用性和制動(dòng)力。(v)l The patient was connected to a television wave monitor.病人的情況曾通過波形監(jiān)視器監(jiān)視。 (n) 翻譯的基本方法 詞義的選擇Skills of Translation acceptation selection2、根據(jù)上下文選擇詞義嚴(yán)格說來，孤立的一個(gè)詞很難確定它是什么意思，因?yàn)橥粋€(gè)詞在不同的場合可能具有不同的意義，因此有些詞必須根據(jù)上下文來確定其詞義。l The countrys industry has developed quickly in the last decade. 過去十年里，我國工業(yè)迅猛發(fā)展。l To develop the instrument, many experts were invited.在研制這種儀器時(shí)請(qǐng)了許多專家。l The function of the engine is to develop the necessary power. 發(fā)動(dòng)機(jī)的功用就是產(chǎn)生所需要的動(dòng)力。翻譯的基本方法 詞義的選擇Skills of Translation acceptation selectionl This cooling system failed. 這個(gè)冷卻系統(tǒng)失效了.l Newtons laws fail to describe the motion of electrons in atoms. 牛頓的一些定律未能闡述電子在原子里的運(yùn)動(dòng)。l If the beam fails, the top layers of the supports will be crushed and the bottom layers torn.如果橋梁垮斷，則支柱的上面幾層會(huì)壓垮，而下面會(huì)破裂。l Few metals occur free. 金屬呈游離狀態(tài)的很少。l One of the parts worked free. 有一個(gè)部件松了。翻譯的基本方法 詞義的選擇Skills of Translation acceptation selection3、根據(jù)專業(yè)內(nèi)容選擇詞義 英語中，同一個(gè)詞在不同的專業(yè)中往往具有不同的詞義。因此，在判斷英語詞的詞義時(shí)，必須考慮到英語著作闡述的內(nèi)容所涉及的概念屬于哪個(gè)學(xué)科、哪個(gè)專業(yè)的。例：powerpower brake 自動(dòng)制動(dòng)器power stroke 工作行程power shaft 傳動(dòng)軸rated power 額定功率power source 電源power fuel 發(fā)動(dòng)機(jī)燃料power tool 電動(dòng)工具power feed 自動(dòng)進(jìn)給power unit 動(dòng)力頭;功率單位 power country 大國翻譯的基本方法 詞義的選擇Skills of Translation acceptation selectionl Knowledge is power. 知識(shí)就是力量。l To drive machines requires power. 開動(dòng)機(jī)器需要?jiǎng)恿Α The power of such a battery is therefore about 30 watts.因而這種電池的功率約為三十瓦。l China will not be the first to use nuclear weapons although considered one of the nuclear powers.盡管中國被看作是核大國之一，但中國決不會(huì)首先使用核武器。翻譯的基本方法 詞義的選擇Skills of Translation acceptation selectionl We have finished repairing that pump.我們已經(jīng)結(jié)束了對(duì)水泵的修理。l These workpieces must be finished on a grinder.這些工件必須在磨床上精加工。l These methods convert raw plastic into finished products. 這些方法均可把塑料原料變?yōu)槌善?。l The stock market crash finished many speculators.股票市場暴跌使許多投機(jī)者破產(chǎn)翻譯的基本方法 詞義的選擇Skills of Translation acceptation selection4、根據(jù)搭配選擇詞義1)形容詞與名詞的搭配：一個(gè)形容詞與不同的名詞搭配，可能具有不同的詞義。一般來說，可根據(jù)與其搭配的名詞來確定形容詞的詞義。例：physical: 物質(zhì)的，物理的，體力的，實(shí)際的physical change ；physical circuit ;physical science 物理變化實(shí)際電路 自然科學(xué) physical constant;
