馬斯克將測試超級高鐵加速和剎車

Tesla CEO Elon Musk has announced plans to test fast braking of its Hyperloop high speed rail project.

特斯拉公司首席執行官埃隆·馬斯克近日宣佈了將對公司旗下Hyperloop超級高鐵項目的快速剎車性能進行測試的計劃。

Designers hope to be able to stop the carriages in just 1.2 km. This would mean going from speeds of 613 km per hour down to zero in just 14 seconds.

設計師希望能讓車輛在1.2公里內剎車，這意味着要在14秒內將時速從613千米降至零。

A report in the Science and Technology Daily suggests that while it would be technically possible to stop the carriages in 14 seconds, the likelihood of it being used in commercial applications will still be a way off.

據《科技日報》報道，雖然從技術層面上看14秒內剎車有可能做到，但這一技術被應用於商業仍需假以時日。

The Hyperloop, developed by Tesla through electromagnetic levitation technology, is based on a pneumatic tube concept.

特斯拉基於氣壓輸送管的概念，採用電磁懸浮技術發展了Hyperloop項目。

A number of countries, including China, have been testing the idea, as it would technically overcome issues such as rail friction, air friction and noise. This allows for dramatically higher speeds.

包括中國在內的多個國家一直在測試這個想法，因爲它能從技術層面克服諸如軌道摩擦、空氣阻力、噪音等問題，從而實現明顯的提速。

Reports have suggested Hyperloop technology could be ready for commercial use by 2021.

報道還表示，Hyperloop技術可能在2021年前完成商用準備。

However, emergency braking is just one of the obstacles for the program. The Science and Technology Daily report suggests designers still haven't been able to find concrete solutions for other problems, including how to keep electromagnetic levitation stable at high speeds and how to conduct passenger tests.

但是，緊急制動只是這個項目的障礙之一。《科技日報》的這則報道稱，設計師們仍然無法找到解決其他問題的具體方案，包括如何在高速的情況下保持電磁懸浮穩定，以及如何進行乘客測試。
