一九七九年底,日本《朝日新闻》评选出一九七九年世界十大科技新闻,其中一条是:磁浮列车的时速突破了五百公里。什么叫磁浮列车呢? 一九六六年,美国最早提出了超导磁浮列车的设想。到一九七二年七月,日本首次进行了实验行车。一个晴朗的早晨,万里无云,阳光洒落在试验场上,这里正在进行着世界上第一次超导磁浮列车的实验性单车运行试验。乳白色的模型车,紧紧吸住在场人们的注意。它长四米,宽一米五,高零点八米,重二吨。开车以后,列车徐徐离开了路面上的轨道,浮了起来,在一段长二百二十米的笔直的线路上,来回飞跑了几次。一九七九年十二月六日试验时,车辆长已为十三点五米,宽三点八米,高二点七米,有十吨重。列车速度快,噪音少,振动
At the end of 1979, Japan’s Asahi Shimbun named the world’s top-10 science and technology news in 1979, one of which was that maglev trains broke through 500 kilometers an hour. What is a maglev train? In 1966, the United States first proposed the idea of a superconducting maglev train. By July 1972, Japan had its first experimental drive. On a sunny morning, cloudless, the sun shines on the test ground, where experimental cycling trials of the world’s first superconducting maglev train are under way. Milky model car, tightly absorbing the attention of the people present. It is four meters long, one meter wide and five meters high, eight meters and weighs two tons. After driving, the train slowly left the track on the pavement and floated up and down several times over a straight 220-meter long line. At the trial on December 6, 1979, the vehicle length was 13.5 meters, 1.3 meters wide and 2.7 meters high, with ten tons of weight. Train speed, less noise, vibration
