人类未来的交通不再局限于地表,可以是三层立体式的。(1)向地心发展。地铁已开了这方面先河。将来我们还可以将整个城市移入地下,不再受风、雨、雪、雾的干扰,不论春夏秋冬、白天黑夜,地下王国将保持恒温。短距离交通可步行或靠水平移动的人行道和上下升降的电梯。长途旅行则可乘通过真空管道的磁悬浮列车。经过磁化的轨道可以对同样磁化过的列车起排斥作用,在磁场强度足够的条件下,列车会按着轨迹升离轨道,没有接触摩擦、震动和噪音,象“飞”起来一样,将管道与世界各主要居民点连接起来形成网络;车内没有地面的昼夜之分,全球可用统一的标准时间,由时差引起的生理节奏失调将成为往事。(2)向 The future of mankind’s traffic is no longer confined to the surface, it can be three-tier three-dimensional. (1) Development to geocentric. Metro has opened the first of its kind in this area. In the future, we will also be able to move the entire city into the ground without interference from wind, rain, snow and fog. The underground kingdoms will maintain constant temperature, no matter in spring, summer, fall, or winter or day or night. Short-distance traffic on foot or by moving the sidewalks and elevators up and down. Long-distance travel can take the maglev train through the vacuum pipeline. The magnetized track can repel the same magnetized train. Under sufficient magnetic field strength, the train will lift off the track according to the track without contact with friction, vibration and noise. Like the “fly” The major settlements in the world are linked together to form a network. There is no day or night of the ground in the car. The world can be used for a uniform standard time. The physiological rhythm imbalance caused by jet lag will become a thing of the past. (2) to
