Current, be carried for railroad by the traffic means with the world's accepted highest security. Railroad is carried have security, quick, locomotive amount is large wait for an advantage, be applied extensively by world each country. Some closer year come, as a result of the promotion of science and technology, railroad is carried also improvement are carried fast, invent and construction applied high speed railroad. And in high speed railroad this one, our country goes in world front row. Although China is tall iron technology is later than the developed country such as Japan, but, as the promising young person's China, had obtained the result that attract worldwide attention on tall iron technology and tall iron construction, at present course of development of Chinese tall iron ranks the world the first. And, china still sells Gao Tie external, wide suffer reputably.
Why can Chinese tall iron take door going abroad, it is safe stability above all, and rate is rapid also, the price is favourable still. All traffic are built, must assure safety above all. I answer back and forth now why Gao Tie is so fast, do not need safety belt however.
The plane encounters convection air, perhaps rise fall to be able to bump. No matter ship has storm, be in maritime it is ramshackle. And the car, as a result of road surface, the metropolis when speed or brake has bigger jolt, but Gao Tie is different. Although tall iron speed is fast, but it has special track, have special amortize brake time, below majority circumstance, it is extraordinary stability, won't have bumpy feeling. So, before tall iron operation, can have tests of all sorts of safe stability test. And most classical is Gao Tie in above of 350km/h of speed per hour, a cup of water that does not cover a lid or coffee, won't asperse because of jolt do not come. Quality of bulk of a cup of water is so small, won't asperse because of stability come out, it is a person what is more,the rather that. Person weight is great, the strength with inertial control is great, stability is much taller than a cup of water. Since Gao Tie is without giving thought to below what circumstance, stability is so good, so safety belt also is bring owls to Athens.
Actually in the final analysis, appropriative moving orbit and enough and sufficient time of reasonable apply the brake, the safe stability that assured high speed railroad moves. And superhigh stability also need not the safety action of safety belt.
