中国研制超级磁悬浮列车,时速可达2900公里 外国人怎么看

esolve(中国)

The world’s fastest train is on the way, although the technology remains at a testing stage in the laboratory.

China is testing the so-called super-maglev train, which operates in a vacuum tube and could reach as high as 2,900 kilometers per hour, Hong Kong Commercial Daily reported Monday.

世界最快列车正在路上,虽然这一技术仍然处于实验室的试验阶段。

据香港《商报》报道,中国正在研制超级磁悬浮列车,采用真空管设计,未来的时速可达到每小时2900公里。

Chinese researchers at the Applied Superconductivity Laboratory of Southwest Jiaotong University in Chengdu have successfully tested a concept train encapsulated in a vacuum tube, which would help reduce the speed limitations imposed by air resistance on regular maglev trains.

Dr. Deng Zigang, who led the project, said his team has already successfully reached a speed of 25 km per minute, and researchers are now working on a vacuum tube, which could lift the speed limit to 50 km per minute in the future.

报道称,在成都的西南交通大学应用超导实验室里,中国研究人员首次成功测试一采用真空管设计的概念车。真空管能够帮助减少常规磁悬浮列车所遇空气阻力施加的速度限制。

这一项目由邓自刚博士领导,他称他的团队已经成功让(列车的)速度达到每分钟25公里,而研究人员目前在打造真空管,未来能够让列车的最大速度提高到每分钟50公里。

If successful, that would mark a great breakthrough in China’s ambitious plan to export the high-speed train to the United States.

China is now in talks to build a high-speed railway that would connect the Chinese capital Beijing with the continental US. The China-US rail link may use the magnetic levitation technology, according to media reports.

如果获得成功,那么将标志着中国向美国出口高铁的这一雄心勃勃计划取得重大突破。

中国正在讨论修建一条连接中国首都北京和美国的高铁。据媒体报道,中美高铁也许采用磁悬浮技术。

The entire journey from China to the US would take only two days.

Currently, the Shanghai Maglev Train connecting Pudong International Airport and Longyang Road subway station operates at a speed of over 430 kilometers per hour, making it the world’s fastest passenger-carrying train.

中国到美国全程将只需要两天。

目前,上海磁悬浮连接了浦东国际机场和龙阳路站,运行时速超过430公里,是世界上速度最快的客运列车。

This is nothing new, more speed of Maglev only need more investment, increasing speed is no bar.

没啥新鲜的。磁悬浮速度越快,意味着投资越大,提速不会是问题。

Kloitra(印度)

Not when you are going for supersonic speeds.

超音速就不是那么回事了

INDIC(印度)

Maglev has poor commercial value if speed goes too high. That’s why the researchers in Westerner countries only working on the speed between 500-600 kmph.

如果速度太快,磁悬浮的商业价值不大。这就是为什么西方国家的研究人员仅仅研究时速介于500-600公里之间的磁悬浮。

cirr(中国)

Yes, yes, expensive yet inferior Japanese high-speed rail tech might find widespread commercial use in India.

Good luck!

是的,不仅昂贵,而且劣等。日本高铁也许会在印度大规模商用

好运吧!

INDIC(印度)

Seeing the reputation of Chinese goods across the world, you gave me goosebump when you called Japanese tech as inferior.

鉴于中国货在全世界的名声,你说日本科技劣等,让我听了起鸡皮疙瘩

Jai_Hind(印度)

Why bring India into it man, he is just comparing the commercial value with the original maglev trains, since you named it super-maglev…..

Anyway I think it will be a very good tech demonstrator and help building the future of chinese railway manyfold….

为什么把印度牵扯进来。他只是在与最初的磁悬浮比较商业价值而已。

总之,我认为这将是非常不错的技术展示,能够成倍地推进中国铁路的未来建设。

Kloitra(印度)

That’s a given, especially when you need vacuum tubes. But having a know how is a good thing.

那是一定的,特别是你需要真空管设计。不过,能够积累知识也不错。

powastick(美国)

Not really, the problem going with higher speed is friction. Maglev has higher efficiency than the a turbojet engine. Planes cruise at 30,000 feet is to reduce friction, thus reducing the amount of fuel. Travelling at high speed at sea level at high speed is not the best idea. China proposal is to use vaccum/low pressure tube but the problem is the cost/safety.

Elon Musk did propose Hyperloop, similiar but slower and cheaper without maglev

不完全是,提高速度面临的问题是摩擦。磁悬浮比涡轮式喷射引擎的效率高多了。飞机在3万英尺高空巡航是为了减少摩擦,进而减少燃油消耗。在海上高速航行这个主意不好。中国的提案是采用真空管设计,就是会面临成本和安全的问题。

马斯克(Elon Musk)提出了超回路列车,速度较慢,但是比磁悬浮更便宜。(三泰虎注:美国亿万富翁艾伦·马斯克在2013年5月的加利福尼亚州D11会议上提出了一个“超回路”超级列车计划)

FaujHistorian(巴基斯坦)

having immense dreams and galactic hopes. Bravo.

this is similar to sending a mission to mars

or traveling to distant stars.

Bravo, our brothers to the North. Bravo.

梦想无边,希望很大,好极了

这就类似向火星发射探测器,或者来一次星际旅行

好极了,北边的兄弟干得好

STEVEN(中国)

we could use the maglev train to deliver goods.

我们可以用磁悬浮列车来运送货物

Kloitra(印度)

Would be way cheaper to use planes. Creating vacuum for long distances is not economical.

用飞机来运还更划算。建造远距离的真空管是不经济的。

powastick(美国)

20-30 years in the future, it might not be economical to use planes as they rely on fossil fuel. You may argue you can create fuel from electricity, it is not feasible using current technology. Electric powered planes are slow too. The main advantage of maglev railway directly with electricity from renewable sources.

未来20-30年,由于严重依赖化石燃料,飞机也会变得不经济。你也许会辩解称,燃料可以从电力转化而来,然而就目前科技来说是不可行的。而且电动飞机的速度缓慢。

磁悬浮的主要优势是直接采用能从可再生能源而来的电力。

STEVEN(中国)

Yes,right now it must be not commerical and the cost of construction must be very high.

I think maybe in the future,it may be achieved.Anyway firstly master this kind of technology.

是的,目前不经济,建设成本太高了

也许未来能够实现。总之,还是先掌握这种技术为妙

Mega fart!!!!!

放屁!

      现在世界兴起比赛,先比高,谁的大楼建得高谁就有本事;不久前新兴的比快,谁的计算机计算得最快,则谁就有本事;现在这比快进入了许多领域、火箭、导弹、星空探测器、飞机、车辆、等等;比深,谁的钻探钻得最深、潜艇潜、深海探测器谁潜得最深,谁就有本事。当然还有比大、比多、比富、比恶、比穷等等都有但目前还不成气候,因而不足挂齿。
