謝謝大家參與,上周活動(dòng)鏈接:http://www.gaoyang168.com/bbs/viewthread.php?tid=7533502&fpage=1 詞匯講解: 1. consider vt.考慮; 認(rèn)為 例句:You could even consider designing your own internship. 甚至可以考慮自己設(shè)計(jì)實(shí)習(xí)機(jī)會(huì)。 2. limitation n.限制; 局限 例句:This limitation is to prevent your making the target too narrow. 這樣的限制是為了防止你的定位太窄。 3. rigid adj.嚴(yán)格的; 僵硬的 例句:The rigid rules are intended to protect workers. 這種死板的規(guī)則就是為了保護(hù)工人。 4. electronic adj.電子的; 電子操縱的 例句:Helen became an electronic engineer. 海倫成了一名電子工程師。 5. improve vt.提高 例句:We can improve quality, reliability, and durability. 我們可以提高質(zhì)量、可靠性和耐久性。 6. flexible adj.靈活的; 易彎曲的 例句:I am converted to flexible work. 我現(xiàn)在轉(zhuǎn)變?yōu)閺椥怨ぷ鳌?br /> 7. prove vt.證明,證實(shí) 例句:A deficit deal will prove impossible. 赤字處理方案會(huì)被證明是無法執(zhí)行的。 短語講解: 1. Scientists hope these new 2D transistors will be used for building high-resolution displays that need very little energy. be used for 用來做… 例句:The grease from pork can be used for frying. 豬肉煉出的油可用來煎炸食物. 2. He adds that researchers have been looking for new materials with special features. look for 尋找 例句:The searcher fannned out to look for the missing boy. 搜尋者散開去找那個(gè)丟失的男孩。 3. "If the layers are very thin the transistor can become flexible, so it doesn't have to be rigid, like it would be in a silicon chip. So people can think of applications like wearable electronics, like, you know, television screens and other things," said Ioannou. think of 考慮; 想起; 有…想法 例句:Don’t think of your product as a computer 不要把你正在設(shè)計(jì)的產(chǎn)品認(rèn)為是計(jì)算機(jī) 4. This is the first time every layer is a single [atom] layer, more or less, and that's the novelty of it. more or less 差不多, 幾乎; 大約 例句: It is now more or less settled. 現(xiàn)在這件事差不多定下來了。 全文翻譯: It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions. 看來電子設(shè)備正在變得越來越小。美國科學(xué)家宣布發(fā)明了首個(gè)二維晶體管。 A transistor is a small electronic device that transfers or carries electronic current. The device helps to create an electrical circuit that provides power to other devices. Scientists hope these new 2D transistors will be used for building high-resolution displays that need very little energy. 晶體管是傳輸電流的小型電子設(shè)備。該設(shè)備幫助創(chuàng)造一個(gè)電路為其它設(shè)備提供電源。科學(xué)家希望這些新型2D晶體管能被用于開發(fā)低能耗的高解析度顯示器。 Two groups of scientists created these 2D transistors. One group is at the Argonne National Laboratory outside of Chicago, the other group is at the University of California. They report that the transistors are only a few atoms thick, any layer of any material that thin may be considered two-dimensional. 兩組科學(xué)家創(chuàng)造了這些2D晶體管。一組在芝加哥郊外的阿貢國家實(shí)驗(yàn)室,另一組在加利福尼亞大學(xué)。他們報(bào)告說,這種晶體管只有只有幾個(gè)原子厚,任何材料的任何一層極薄都可以被認(rèn)定為二維。 Usually transistors are made with the element silicon. But the scientists say they use materials that have even better electronic properties. Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations. 通常晶體管由硅元素制成。但科學(xué)家稱,他們使用了具有更好電學(xué)性能的材料。計(jì)算機(jī)處理器,內(nèi)存芯片,電視屏幕和其它電子裝置包含了數(shù)十億個(gè)硅基晶體管。但這些極小的電氣部件都有一定的局限性。 Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be. He adds that researchers have been looking for new materials with special features. He says researchers want transistors to be see through and soft. Dimitris Ioannou是喬治•梅森大學(xué)的一位電氣工程教授。他說傳統(tǒng)晶體管已經(jīng)耗盡其潛能。他補(bǔ)充說,研究人員一直在尋找具有特殊功能的新材料。他說,研究人員希望晶體管能夠透明、柔軟。 "If the layers are very thin the transistor can become flexible, so it doesn't have to be rigid, like it would be in a silicon chip. So people can think of applications like wearable electronics, like, you know, television screens and other things," said Ioannou. Ioannou說,“如果各層非常薄,晶體管就能變得更靈活。它不一定要像它在硅芯片上那樣是剛性的。人們能想象到的應(yīng)用包括可穿戴設(shè)備,電視屏幕等等! These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens. 這種新型晶體管可以承載更高的電流。與傳統(tǒng)晶體管相比,它們的傳輸速度也更快。這對(duì)高清晰屏幕來說非常重要。 Dimitris Ioannou says the scientific success could prove very useful in the future. Dimitris Ioannou稱,這一科學(xué)成就在未來將被證明非常有用。 "This is the first time every layer is a single [atom] layer, more or less, and that's the novelty of it. Now, how good and how useful it will be, it's still in research phase, but it certainly is an advance," said Ioannou. Ioannou說,“這是第一次每層都是單個(gè)原子層左右,這就是它的新穎。現(xiàn)在來說,它未來的優(yōu)點(diǎn)和用途仍處于研究階段,但它確實(shí)是一次進(jìn)步。” Scientists say there is no good method for printing a large number of these new transistors on one base material, but they believe that someday it may be possible. 科學(xué)家說,目前尚沒有什么好辦法基于一種基礎(chǔ)材料打印大量這種新型晶體管,但他們認(rèn)為總有一天可實(shí)現(xiàn)這點(diǎn)。 |
