[简答题]High-speed ground transportation (HSGT) technologies with vehicle speeds exceeding 150 mph can be divided into two basic categories: High-speed rail (HSR) systems, with top speeds between 150 and 200 mph, use steel wheels on steel rails, as with traditional railroads, but can achieve higher speeds because of the design of both the rail bed and cars. High-speed magnetic levitation (MAGLEV) systems, with top speeds between 250 and 300 mph, use forces of attraction or repulsion from powerful magnets placed in either the vehicle or the guideway beneath it both to lift the vehicle above the guideway and to propel it forward. A MAGLEV vehicle can be likened to a flying train or a guided aircraft. If linked effectively with highways and air service, HSGT technologies-particularly MAGLEV—could have a significant impact on congestion in the future. When comparing HSR with MAGLEV technologies, MAGLEV appears to be the technology of choice. Though the new generation of HSR technology can reach co
[单项选择]Vibrations in the ground are a poorly understood but probably widespread means of communication between animals.
It seems unlikely that these animals could have detected seismic "pre-shocks" that were missed by the sensitive vibration-detecting equipment that clutters the world’s earthquake laboratories. But it is possible. And the fact that many animal species behave strangely before other natural events such as storms, and that they have the ability to detect others of their species at distances which the familiar human senses could not manage, is well established. Such observations have led some to suggest that these animals have a kind of extra-sensory perception. What is more likely, though, is that they have an extra sense-a form of perception that people lack. The best guess is that they can feel and understand vibrations that are transmitted through the ground.
Almost all the research done into animal signaling has been on sight, hearing and smell, because these are s
