1. The wheel/rail contact on rail-joint is line/area contact so that the rail joint has great elastic-plastic strain. Finally, rail break in the rail-joint. 计算表明：由于接头位置轮轨接触为线面接触，造成了钢轨接头处塑性应变较大，最终导钢轨头部破损。
2. Continuously Welded Rail (CWR) track across section is a new type rail track structure, the rail joints are removed, and the rail track is completely jointless, and it has many merits. 跨区间无缝线路是一种新型轨道结构型式，完全消除了钢轨接头，彻底实现了线路的无缝化，其优点十分明显。
3. Roaring rail (or howling wheel) noise, which can exceed the smooth wheel/rail rolling noise by 10 to 20 decibels, is produced by short-pitch corrugations on the rail and/or wheels. 钢轨表面的短波波浪磨耗会导致钢轨或车轮产生轰鸣噪声，轰鸣噪声比平稳的滚动噪声高10-20分贝。
4. The response of rail/wheel can be reduced by decreasing the receptance of wheel/rail and matching of wheel/rail receptance. 降低轮/轨导纳可以有效降低轮/轨高频振动响应，轮轨导纳合理匹配有利于轮轨系统响应的合理分配。
5. light rail, heavy rail, crane rail, galvanized coil, boiler steel plate, low carbon Steel plate and other steel products. 轻轨、重轨、吊车轨、镀锌卷、锅炉板、低碳钢板等钢材。
