世界上第一台蒸汽机车和第一条由动力机械牵引的公用铁路诞生至今已近200年,由于机车设计、动力能源、轨道结构等不断改进和发展,车速由每小时20公里提高到200余公里。然而,据实验,车轮在铁轨上行进,其极限是每小时只能达350公里,超过此速车轮就打滑了。因此,要想进一步提高车速,只有使列车离开铁轨“飞”,于是便产生了“磁悬浮列车”(亦称磁垫列车)的设想和研制。目前,日本、西德、美国都在研制磁悬浮列车,并取得了可喜的成果。日本研制磁悬浮列车的积极性最高,技术最先进,计划最庞大。初步决定在东京与大阪之间修
The first steam locomotive in the world and the first public railway towed by power machinery have been built nearly 200 years ago. Due to the continuous improvement and development of locomotive design, power and energy, orbit structure, the speed has been raised from 20 km / h to 200 / h Km. However, according to experiments, the wheels traveling on rails have a limit of only 350 kilometers an hour, and skips over this speed wheel. Therefore, in order to further increase the speed, only by leaving the train to leave the track “fly”, then the “maglev train” (also known as magnetic cushion train) was conceived and developed. At present, Japan, West Germany, the United States are developing maglev train, and achieved gratifying results. Maglev train developed in Japan the highest enthusiasm, the most advanced technology, the largest plan. Initial decision to repair between Tokyo and Osaka
