number of axles meaning in English
轴数
Examples
- The results show that the wayside noise increases 8db - 12db , if the train ' s velocity increase two times ; and increases 3 db , if the number of axles increase tow times ; and decreases 3db , if the distance far away from the track increase tow times damping loss factor increases , the wayside noise decreases ; coupling loss factor increase , the wayside noise increase
预测结果表明：列车通过时，在其他条件不变的情况下，列车速度增加一倍，轮轨辐射噪声大约增加8db 12db ；列车轴数增加一倍，轮轨辐射噪声大约增加3db ；预测点距轨道距离增加一倍，轮轨辐射噪声大约降低3db 。
