US carmakers are struggling to reconcile customers’ growing interest in running vehicles on newly abundant natural gas with the logistical challenges of supplying the technology for the still-niche market, according to senior automotive executives.汽车业高管表示,美国汽车制造商难以满足顾客对天然气动力汽车日益增强的兴趣,因为在这一仍属缝隙的市场供应相关技术仍有不少物流挑战。近年美国天然气供应变得充足。The interest in compressed natural gas vehicles is the latest result of the gas glut following the shale oil and gas revolution. New drilling techniques have unlocked vast, previously inaccessible gas supplies in shale rocks.对于压缩天然气汽车的兴趣是页岩油气革命之后大量天然气供应的结果。新的钻探技术从页岩中释放出以前无法获取的大规模天然气供应。Normal vehicles can use the plentiful fuel – which produces fewer greenhouse gas emissions than petrol or diesel fuel – with the addition of large fuel tanks and minor modifications to the engine. Large customers can sign long-term contracts to buy natural gas at low prices. However, Chrysler, smallest of the big three US carmakers, is offering only one vehicle with a CNG fuel option, while General Motors, largest by sales, is offering only a few models.一般的汽车可以利用这种储量丰富的燃料(其产生的温室气体排放少于汽油或柴油燃料)——只要加装体积较大的气罐,并对发动机进行少许改动。大型客户可以签订长期协议,以低价购买天然气。然而,美国三大汽车制造商中规模最小的克莱斯勒(Chrysler)仅提供一款以压缩天然气为动力的汽车,而销量最大的通用汽车(GM)推出的车型也很少。Chris Collins, director of advanced powertrains for Chrysler, said Chrysler was confident in CNG’s long-term future as a fuel. While other manufacturers handed work to install CNG equipment to smaller, after-market suppliers, Chrysler was building a CNG-powered pick-up truck on its own assembly lines.克莱斯勒先进动力总成主管克里斯#8226;柯林斯(Chris Collins)表示,克莱斯勒对于压缩天然气作为一种燃料的长远前景充满信心。尽管其他制造商将安装压缩天然气设备的任务外包给规模较小的售后供应商,但克莱斯勒正在自己的装配线上生产一款以压缩天然气为动力的皮卡。General Motors was offering only “a handful” of pick-up trucks, two full-size vans and the Chevrolet Impala passenger car with CNG, Mark Maher, GM’s chief engineer for powertrain integration, said. The company was working with after-market suppliers but wanted to keep tight control of the work, according to Mr Maher.通用汽车动力总成集成总工程师马克#8226;马赫(Mark Maher)表示,通用汽车提供的以压缩天然气为动力的车型包括“少量”皮卡、两款全尺寸货车以及雪佛兰Impala(Chevrolet Impala)轿车。他表示,通用汽车与售后市场供应商合作,但希望严格控制这块业务。Only Ford, the US’s second-biggest carmaker by sales, is offering a comprehensive range. Jon Coleman, Ford’s sustainability manager for fleet sales, said it was using after-market suppliers to install CNG equipment and offering the “broadest portfolio of vehicles” it could.只有在美国市场销量居第二位的汽车制造商福特(Ford)提供广泛的系列产品。福特车队销售可持续发展经理约翰#8226;科尔曼(Jon Coleman)表示,该公司正利用售后市场供应商安装压缩天然气设备,并尽力提供“最齐全的车型组合”。All of the companies attributed the limited demand for CNG vehicles to the shortage of CNG filling stations and the cost and size of the fuel tanks.这些公司都将压缩天然气汽车需求有限,归因于压缩天然气充气站短缺以及气罐的成本和尺寸。But John O’Dell, a senior editor at Edmunds.com, the automotive site, said that, if those challenges could be overcome, the attractions were significant. “Natural gas is as close as possible to a no-compromise replacement for gasoline or diesel.”然而,汽车网站Edmunds.com高级编辑约翰#8226;奥戴尔(John O’Dell)表示,如果能够克这些挑战,吸引力将很可观。“天然气是一种可取代石油或柴油、且不会在性能上打折扣的选择,在这方面近乎完美。” /201312/270841。

I#39;ve been snapping photos of everything in front of me for the last week. If we#39;ve passed, even for a moment, I probably have a picture of your face.过去一周我一直在抓拍出现我面前的每样东西。如果我们曾擦肩而过,哪怕就一瞬间,我也可能会有你的脸部照片。I#39;m not a spy, but I#39;ve been using gear you might associate with 007. New matchbook-size cameras that clip to your tie or shirt let you capture a day#39;s worth of encounters, then upload them to the Internet to be remembered forever.我并非间谍,但我的装备也许会让你想到007。新式的火柴盒大小的相机可夹在领带或衬衫上,让你能够抓拍值得记录的瞬间,然后上传至互联网永久保存。Why on Earth would anybody want to do that? After trying out two devices that recently began shipping, the 9 Narrative Clip and 9 Autographer, I think the answer for many will be why wouldn#39;t you?怎么会有人想干这种事?在试用了新近上市的279美元的Narrative Clip和399美元的Autographer两款设备之后,我想对很多人来说,是为什么不呢?Yes, I took gigabytes of boring photos of me sitting in front of a computer at work. But when I took the tiny cameras hiking or hanging out with kids, they produced Instagram-worthy shots. (I also discovered surprising uses, like when I scanned my photo log to discover where I#39;d misplaced my watch.)没错,我拍了大量自己坐在电脑前工作的无聊照片。但当我徒步或和孩子们出去玩的时候,这些袖珍相机会拍出很适合分享到Instagram的快照。(我还发现了意外的妙用,比如通过检索照片记录来找出我把手表丢在了哪里。)Wearable cameras are a potential solution to the growing annoyance of people holding their phones in front of their faces throughout birthday parties, concerts and other important moments, instead of just living them.在生日聚会、音乐会及其他重要场合,人们总是把手机举在面前到处拍,而不懂得享受当下,这样的行为越来越令人讨厌。可穿戴相机或许是很好的解决办法。But there#39;s a cost to amassing so much photographic evidence. The tiny cameras made others uncomfortable when they found out they were being recorded. Some friends wouldn#39;t hug me; gossiping colleagues kept asking, #39;Is that thing on?#39; These devices upset a fundamental (though arguably flawed) assumption that even in public, you aren#39;t being recorded.但要积累足够多的照片也不是轻而易举的事。当人们发现袖珍相机正在拍摄自己时,会感到很不自在。一些朋友不再拥抱我了;八卦的同事们总是问:“那玩意儿开着吗?”这类设备颠覆了一个基本观念(虽然不一定正确):就算是在公开场合,随便拍人也是不应该的。Makes you squirm, doesn#39;t it? One reason I wanted to review these cameras is that this kind of technology isn#39;t going away. #39;Always on#39; cameras are becoming popular in home electronics like the Xbox One and a new wave of streaming security systems. Now you can buy cameras that attach to your wrist, ear, bike helmet and eyeglasses.让人不舒,对吧?我之所以想对这种相机发表的一个原因是此类技术正方兴未艾。“无间断”摄像头正在Xbox One等家用电子设备以及新一轮流媒体视频安全系统产品中日益受到追捧。现如今,你可以买到戴在手腕和耳朵上、安装在自行车头盔和眼镜上的相机了。The two cameras I tested are meant for everyday use. On the surface, they seem very similar: plastic clip-ons that silently take photos and store them until you upload them to a phone or computer. They arrange the photos in a contact sheet on your phone and use software to highlight the most interesting shots, or give you a sped-up of your day.我试用的这两款相机是为日常使用设计的。其外观大同小异,都是可夹式塑料外壳,它们默默地拍照并存储,直到你把照片上传到手机或电脑里。它们把照片储存在手机的图片索引里,还会用软件高亮最有趣的照片,或者快速播放照片,以视频的形式把你的一天呈现出来。The Narrative is the least obtrusive. It could be easily mistaken for a tie clip. The Narrative has no buttons or screen, and just one function: It takes a photo of whatever is in front of it every 30 seconds, more than 2,000 a day, with quality comparable to the iPhone 4#39;s camera.Narrative很不起眼,很容易被误认为是领带夹。它没有按键和显示屏,只有一个功能:每隔30秒拍下它面前的景象。一天下来就有超过2,000张照片,其画质堪比iPhone 4的摄像头。A sensor makes sure the photos are always upright, no matter how the clip is oriented, while a GPS chip inside notes where you are each time it takes the photo. Tap on the Narrative twice and it will snap a photo right away.无论相机处于何种方位,它的感应器都会确保照片端正。同时,内置的GPS芯片会记录每张照片的拍摄地点。连续敲击两下,相机就会立刻抓拍一张。The pricier Autographer is three times larger, making it flop over when I attached it to my shirt pocket. It packs a 5-megapixel camera with fisheye lens and five sensors -- including an accelerometer, compass and thermometer -- in order to take a picture when it thinks your surroundings have changed. It can use Bluetooth to transfer shots wirelessly to a phone or computer right away. All of this extra tech means the battery lasts about 10 hours, compared with the Narrative#39;s 30.Autographer价格较贵,比Narrative大三倍,夹在衬衫衣兜上会外翻。它配置了一个500万像素的鱼眼镜头和五个传感器――其中包括加速计、指南针和温度计――这使它能感知周遭环境变化,及时拍照。它还可通过蓝牙即时把快照无线传输到手机或电脑上。所有这些额外的技术配置意味着它的电池只能续航约10小时,而Narrative是30小时。What are you supposed to do with all of those photos? More than 1,000 shots taken on my hike this Sunday weren#39;t worth keeping. But 15 were delightful, unposed shots of my friends and their kids at sunset. You can#39;t get a 7-year-old kid to look that naturally happy with a regular camera pointing in his face, but the candid camera did. I could imagine taking one of these cameras to special events or on vacation.该怎么处理这么多照片呢?我周日徒步途中有1000多张快照都没有保留价值,但有15张非常赞,抓拍到了我朋友和他们的孩子在日落时分最自然的瞬间。让一个七岁的孩子在普通镜头前表现得如此开心大方是不可能的,但袖珍相机做到了。我想我会带个袖珍相机去特殊活动或度假的。Judging based on price, shape and battery life, the Narrative would seem to be the better product. But after using both cameras, I realized the Autographer was superior because its design better respected my interactions with friends and strangers alike.综合价格、外形和电池续航来看,Narrative看起来是更好的产品。然而在试用过这两款相机之后,我意识到Autographer更胜一筹,因为它的设计更好地尊重了我与朋友及陌生人之间的互动。Very few people noticed I was wearing the Narrative#39;s tiny clip. It made me feel like a creep for not disclosing to friends and people on the street that I was photographing them. It offers no indication it#39;s taking a picture and continues snapping away unless you turn it over or put it into a pocket (which you need to remember to do when you go to places like the toilet). After wearing it for a few days, I decided to tape a camera icon on it.只有很少几个人注意到了我戴着Narrative。不告诉朋友和街上的行人自己在拍他们让我觉得自己像个怪人。它没有任何拍照提示,并且除非你把它翻过来或放进兜里(当你要去洗手间等场所时一定记住这点),否则它会不断地拍摄。在戴了几天之后,我决定给它贴上一个相机图标。The Autographer announces itself as a camera. Each time it snaps, a faint blue light flashes on its front. More important, its lens is highlighted by a bright yellow circle and has a rotating cover so everyone can see when it is and isn#39;t watching.Autographer则会标榜出自己的相机属性。当它拍照时,机身正面会闪一下微弱的蓝光。更重要的是,其镜头用一个醒目的黄圈标出,还有个旋转镜头盖,这样所有人都能看出它是否正在拍摄。In short, Autographer#39;s design helps keep people from being jerks. The fisheye lens means you can#39;t accidentally take head-on photos of people unless you are very close to their faces. Since the camera connects wirelessly to your phone, you can review your shots right away -- and delete shots if anybody asks. By default, Autographer only saves all your photos on your computer or phone rather than its own servers.简言之,Autographer的设计有助于防止人们被偷拍。鱼眼镜头使你不会无意间拍到别人的正脸,除非你离他们的面部非常近。由于它与你的手机无线连接,所以你可以立即查看照片,如果有人要求的话也可以立即删除。根据默认设置,Autographer只会把照片保存到你的电脑或手机内,而不是它自己的务器内。All these concerns are rooted in civility. There#39;s nothing actually illegal about using one of these cameras in most venues in the U.S., outside of restrooms, casinos and other businesses that expressly forbid them.所有这些顾虑都是出于礼仪考虑。除了洗手间、及其他明文禁止拍照的场所之外,在美国大部分场所使用这种相机都没什么不合法的。Narrative#39;s Swedish creators say their clip wouldn#39;t make a good spy camera because it isn#39;t as small as the latest snoop gear and its 30-second automatic timer is too arbitrary. Also, their research found people who spotted it did generally understand that the device was a camera. #39;If you want a camera to spy on your friends, we don#39;t want you as a customer,#39; company co-founder Oskar Kalmaru said, #39;And we intentionally made the Narrative Clip bad for use in cases like that.#39;Narrative的瑞典制造商称其产品并不是一款好的间谍相机,因为它没有最新的侦查装置小巧,并且30秒的自动计时器太刻板了。同时他们的研究表明,注意到Narrative的人基本上都会认识到它是个相机。公司联合创始人奥斯卡#12539;卡尔玛鲁(Oskar Kalmaru)说:“如果你想要一款相机来侦查你的朋友,那我们并不希望你成为我们的客户。我们是有意让Narrative Clip在这种情况下表现不佳的。”The U.K.-based makers of Autographer take the extraordinary step of including an etiquette guide in its box, with suggestions like #39;pause your image capture if you are in proximity to people you don#39;t know for a long period of time.#39;Autographer的英国制造商则更进一步,在包装盒内附上了一份礼仪指南,包括诸如“若您长时间近距离接触不认识的人,请暂停拍摄图像”这样的建议。For me, wearing either camera meant I was constantly on guard, y to turn it off if a situation became too private to capture.就我而言,戴着任何一款相机都意味着我得时刻保持警惕,如果遇到了不宜拍摄的私密场景,要马上把它关掉。We might eventually get used to the idea that we#39;re being constantly watched, but for now I think a baseline rule ought to be some kind of notice: I#39;m taking your photo.也许终有一天我们会习惯时刻被监视这个概念,但在现阶段我认为一个基本准则应当是某种告知:我正在给你拍照。The experience made me realize we need a big public conversation about how to live with ubiquitous sensors. Part of that means developing criteria to judge technology beyond basic hardware or software design. Let#39;s call it the #39;relationship test#39;: How does this piece of technology change not just my life, but how I interact with you?这两款相机的体验使我意识到,我们需要一场公开大讨论,讨论如何去忍受无处不在的传感器。这种讨论还意味着形成评判除基础软硬件设计之外的科技的标准,让我们称之为“关系测试”吧:这项技术如何改变了我的生活以及我与你互动的方式? /201402/276436。
