我设计的新型钢轨是将普通钢轨的两端分别制成“V”形与倒“V”形,安装时,后一节钢轨的轨尖与前一节钢轨的凹端相距一定距离。这样,既解决了热胀冷缩问题,又由于在前一条钢轨上未走完便上了后一条钢轨,可以避免火车行驶时的噪声与颠簸。无震钢轨@启迪$江苏省盐城市马沟中学!学 The new type of rail I designed was to make the two ends of the ordinary rail into “V” shape and inverted “V” shape respectively. When it is installed, the rail tip of the rear rail is at a certain distance from the concave end of the rail in the previous section. In this way, not only the problem of thermal expansion and contraction is solved, but also the rear rail can be avoided since the rail is not completed on the front rail.
