　　據(jù)美國(guó)聯(lián)邦航空管理局的發(fā)言人勞拉•布朗(Laura Brown)稱(chēng)，國(guó)會(huì)限制美國(guó)聯(lián)邦航空管理局在國(guó)際民用航空組織(International Civil Aviation Organization)的建議之外，對(duì)機(jī)上電池供電設(shè)備進(jìn)行更多限制。

　　The organization, a U.N. agency, says the devices should not be transported on passengerplanes as cargo or in checked baggage.

　　后者是聯(lián)合國(guó)的下屬機(jī)構(gòu)，它表示，這些設(shè)備不應(yīng)該在客機(jī)上作為貨物運(yùn)輸，也不應(yīng)在托運(yùn)行李中運(yùn)輸。

　　As for in-cabin use, the organization defers to each country’s rules.

　　至于在機(jī)艙內(nèi)的使用，該組織留給每個(gè)國(guó)家自行規(guī)定。

　　Any attempt to seriously restrict or even ban devices powered by lithium-ion batteries wouldprobably face an outcry from travelers, who have come to consider them an indispensable partof modern life.

　　旅客們已經(jīng)把手機(jī)視為現(xiàn)代生活不可缺少的一部分，任何嚴(yán)格限制甚至禁止這些以鋰離子電池設(shè)備的嘗試都可能招致強(qiáng)烈抗議。

　　另外，還有誰(shuí)來(lái)執(zhí)行以及如何執(zhí)行這些規(guī)定的問(wèn)題。

　　Airport security check-in processes are already long and tedious, without adding a new layerof scrutiny.

　　機(jī)場(chǎng)安檢托運(yùn)過(guò)程已經(jīng)很漫長(zhǎng)無(wú)聊，更別提再加一層審查。

　　Until a few years ago, before the in-cabin use of phones and other electronic devices wasallowed below 10,000 feet, it was widely known that passengers surreptitiously defied the rule.

　　幾年前，在1萬(wàn)英尺以下的機(jī)艙內(nèi)使用手機(jī)等電子設(shè)備不再被禁止。在那之前，眾所周知，乘客往往偷偷地自行其是。

　　Flight attendants complained that it was impossible to police.

　　乘務(wù)員抱怨說(shuō)，他們無(wú)法管束。

　　So the goal is to contain the hazard.

　　所以，目標(biāo)是控制危險(xiǎn)。

　　In the event of a lithium-ion battery fire in flight, FAA standards may help minimize thedamage.

　　當(dāng)飛行中遇到鋰離子電池著火的情況時(shí)，美國(guó)聯(lián)邦航空管理局的標(biāo)準(zhǔn)也許可以幫助把損失降低到最小。

　　Seat covers, carpets, curtains and dividers are made of special materials that are flameretardant, even against a lithium-ion battery fire, which burns in the neighborhood of 1,000degrees Fahrenheit, according to Isidor Buchmann, an engineer who runs the informational siteBatteryUniversity.com.

　　座套、地毯、窗簾和分割簾由特殊的阻燃材料做成，甚至能抵擋鋰離子電池引發(fā)的火情。據(jù)信息網(wǎng)站BatteryUniversity.com的運(yùn)營(yíng)工程師伊西多•布克曼(Isidor Buchmann)稱(chēng)，這種材料在周?chē)鷾囟冗_(dá)到1000華氏度(約合538攝氏度)時(shí)會(huì)燃燒。

　　Some experts say those standards could suffice.

　　有些專(zhuān)家稱(chēng)，這些標(biāo)準(zhǔn)已經(jīng)足夠。

　　It’s damned near impossible to propagate a fire on an airplane, said George J. Ringger, anaeronautical engineer with his own consulting company who specializes in cabin interiors.

　　在飛機(jī)上，火勢(shì)幾乎不可能蔓延，航空工程師喬治•J•林格(George J. Ringger)說(shuō)。他自己的咨詢(xún)公司專(zhuān)門(mén)提供機(jī)艙內(nèi)部設(shè)施方面的建議。

　　Could a passenger get burned? Yes.

　　乘客是否有可能被燒傷?有可能。

　　Would there be smoke that would propagate in the cabin? Do crews have protocols? Yes.

　　煙霧是否有可能在機(jī)艙蔓延?機(jī)組成員是否有應(yīng)急方案?是的。

　　But some other fire and safety experts are not as sanguine.

　　但是其他一些火災(zāi)和安全專(zhuān)家不這么樂(lè)觀。

　　A laptop battery fire could take hours to burn itself out.

　　如果手提電腦的電池起火，可能要在數(shù)小時(shí)后才能燒盡。

　　And the smoke emitted would be abundant and toxic.

　　可能釋放大量有毒煙霧。

　　Michael Gilchrist is an engineer and co-owner of PlaneGard, a maker of a case meant to containthe fire and smoke if a battery starts to malfunction.

　　工程師邁克爾•吉爾克里斯特(Michael Gilchrist)是PlaneGard公司的聯(lián)合所有者。該公司生產(chǎn)一種箱子，電池功能失常時(shí)放進(jìn)去，可以限制火和煙霧蔓延。

　　Customers include Air Tahiti Nui, which carries the PlaneGard case on transoceanic flights.

　　它的客戶(hù)包括塔希提航空公司(Air Tahiti Nui)，后者在跨大洋的航班上配備了PlaneGard盒。

　　With a full-blown laptop, you see what happens, Gilchrist said. You have a 35- or 40-minuteevent.

　　對(duì)于一臺(tái)完整的筆記本電腦，情況會(huì)是這樣，吉爾克里斯特說(shuō)，那會(huì)是一場(chǎng)持續(xù)35至40分鐘的事故。

　　That could cause a lot of problems.

　　會(huì)導(dǎo)致很多問(wèn)題。

　　谷歌旗下DeepMind在語(yǔ)音生成領(lǐng)域取得突破

　　Google’s DeepMind division has claimed a big leap forward in producing computer-generatedspeech, potentially bringing forward the day when machines sound as natural as humans.

　　谷歌(Google)旗下的DeepMind稱(chēng)，在計(jì)算機(jī)語(yǔ)音生成領(lǐng)域取得巨大飛躍。這一技術(shù)進(jìn)步可能會(huì)令機(jī)器像人一樣自然發(fā)聲的一天提前到來(lái)。

　　Researchers at the UK-based artificial intelligence arm said tests of their system with humanlisteners, though unavoidably subjective, had shown that the technology halves the qualitygap that exists between today’s computer systems and human speech.

　　這家總部駐英國(guó)的人工智能分公司的研究人員表示，由人類(lèi)聽(tīng)眾對(duì)其系統(tǒng)的測(cè)試(盡管這種測(cè)試不可避免地帶有主觀性)顯示，該技術(shù)將目前計(jì)算機(jī)系統(tǒng)與人類(lèi)說(shuō)話間存在的質(zhì)量差距縮小了一半。

　　One person familiar with the research said the system, called WaveNet, was not being employedin any of Google’s products yet, and that the massive computing power it needed to generatespeech made it impractical for real world use for the foreseeable future.

　　一位知情人士表示，這一名叫WaveNet的系統(tǒng)尚未被用于谷歌任何產(chǎn)品。該技術(shù)在生成語(yǔ)音時(shí)需要極大的運(yùn)算能力，令它在可以預(yù)期的未來(lái)無(wú)法實(shí)際運(yùn)用到真實(shí)世界。

　　The research that led to WaveNet, along with a number of samples of speech generated by thesystem, was published online on Thursday.

　　周四，WaveNet的相關(guān)研究以及一系列該系統(tǒng)生成的語(yǔ)音樣本被發(fā)布到網(wǎng)上。
