| 摘要: |
| 列车提速使得其空气阻力明显增大。为了减小空气阻力, 列车车厢气动外形的研究变得愈加重要。在低速风洞中获得的实验结果表明, 对现型列车车厢局部外形稍加改善, 就能使得其空气阻力大为降低。这是实现我国列车提速最为有效的途径之一。 |

| Abstract: |
| Increasing speed makes aerodynamic drag of train increase obviously. To decrease aerodynamic drag, it is important to improve aerodynamic contour of train. Experiment results show that a little change of partial contour of train can greatly decrease aerodymic drag. This is an effective way to decrease aerodynamic drag of increasing speed train. |
