The next decade could see commuters
speeding to work at about 300 miles per hour aboard magnetic levitation
vehicles, according to a report by Argonne National Laboratories. But before
"maglev" vehicles can become commercial successes, the report says, people need
to stop thinking of them as high-speed trains. Instead, consider them low-flying
aircraft. Argonne contends that maglev vehicles will be best suited to replace
commuter aircraft. Plane flights under 600 miles are the least energy-efficient,
and maglev "planes" should cut these fuel needs by up to 75 percent. Reportedly,
the money saved by a 2,000- mile maglev network linking major cities world more
than pay for its construction in 20 years. The quiet purr of levitating crafts
would also be a balm for neighborhoods tormented by the roar of conventional
takeoffs and landings. The technolo A. The Future of Transportation B. Argonne Develops Maglev Train C. The Disadvantages of Commuting by Airplane D. Commuting in the Future [单选题]在进行重大危险源评价时,如果一种危险物质具有多种事故形态,且它们的事故后果相差不大,则评价事故后果时应遵循的原则是()。
