英語(yǔ)專(zhuān)業(yè)八級(jí)翻譯模擬練習(xí)附譯文
英語(yǔ)專(zhuān)八翻譯主要測(cè)試考生的漢譯英能力，題源一般是我國(guó)報(bào)刊雜志上的文章和一般文學(xué)作品。要考生忠實(shí)愿意，流暢翻譯，難度不小，大家平時(shí)還需熟練掌握翻譯理論和技巧.以下是小編為大家搜索整理的英語(yǔ)專(zhuān)業(yè)八級(jí)翻譯模擬練習(xí)附譯文，希望對(duì)正在關(guān)注的您有所幫助!更多精彩內(nèi)容請(qǐng)及時(shí)關(guān)注我們應(yīng)屆畢業(yè)生考試網(wǎng)!
美國(guó)洛斯阿拉莫斯國(guó)家實(shí)驗(yàn)室的科學(xué)家們采用了一種新技術(shù)，可以觀(guān)察到原本很難在物體表面上看見(jiàn)的指紋。 這項(xiàng)技術(shù)將一束密集的X光對(duì)準(zhǔn)留有指紋的物體表面，并根據(jù)掃描結(jié)果創(chuàng)建出計(jì)算機(jī)圖像。
傳統(tǒng)的方法是通過(guò)常規(guī)光線(xiàn)使指紋顯示出來(lái)，而且要借助粉末等物質(zhì)，這會(huì)改變指紋保存狀況。而該新方法使用了一種“微X射線(xiàn)束熒光技術(shù)”，可以探測(cè)到指紋攜帶的化學(xué)成分，卻不會(huì)改變指紋的保存狀態(tài)。
該實(shí)驗(yàn)室的一位科學(xué)家瓦希德·馬吉德表示，對(duì)那些大實(shí)驗(yàn)室來(lái)說(shuō)，這是獲取用其他方法看不到的印跡的最好方法。
馬吉德說(shuō)：“這項(xiàng)技術(shù)填補(bǔ)了一項(xiàng)空缺。如果沒(méi)有這項(xiàng)技術(shù)，某些印跡就會(huì)變得毫無(wú)意義。比如說(shuō)，如果是深色表面上的指紋，普通技術(shù)確實(shí)無(wú)法精確地探測(cè)到它們;如果是青少年或小孩的指紋，他們的指尖留下的化學(xué)成分(和成人)是不同的，而且這些指紋附著在物體表面的時(shí)間并不久，因此不適宜使用傳統(tǒng)的分析方法。”
豪夫里洛說(shuō)：“這是清晰顯示指紋的一種新途徑。我們查找印跡時(shí)不再只觀(guān)察手指分泌的油脂和殘留有機(jī)物，而是專(zhuān)注于其背后隱藏的特殊化學(xué)成分。”
該實(shí)驗(yàn)室發(fā)明的這種新型指紋探測(cè)法的創(chuàng)新之處在于它包含了計(jì)算機(jī)軟件技術(shù)和機(jī)器操作方法。但是這一技術(shù)也并非眾人皆宜。豪夫里洛笑著說(shuō)：“我們已經(jīng)收到了一些負(fù)面評(píng)論。一位批評(píng)者對(duì)我們說(shuō)它壓根不實(shí)用。但我們工作的目標(biāo)是證明這種技術(shù)是切實(shí)可行的。”
參考譯文：
Los Alamos National Laboratory scientists are using a new technique to see fingerprints on surfaces that typically make them invisible. The technology focuses a tight beam of X-rays on surfaces with fingerprints and creates a computer picture out of those scans.
The conventional methods are meant to bring out fingerprint patterns with regular light and they have to treat those with powder, which alters them. The new method uses a technology called mini-X-ray fluorescence to detect chemical elements in fingerprints without altering them.
For big labs, the method could be a great way to bring out prints that can’t be seen any other way, said Vahid Majidi, a lab scientist.
"The technique fills a unique niche," Majidi said. "These are prints that would otherwise be useless. If you have prints on a dark surface, for example, they really don’t develop well using normal techniques. If you have prints from an adolescent or child, the chemicals in the fingertips are different and don’t stick around long enough for traditional methods."
"This is a new approach to fingerprint visualization," Havrilla said. "We’re lifting prints, but instead of looking at the finger’s natural oils and organic residues we’re looking at elemental features left behind."
What’s new is the method the lab has created to see them which includes computer software and ways of manipulating the machinery, Worley said. But the technique isn’t for everyone.
"We’ve already had some negative comments on it," Havrilla said with a laugh. "One reviewer told us it’s just not practical. But the goal of our work was to demonstrate that it was feasible to see these things."
