rail rate

Coolidge added up the room rate and two rail tickets back to the campus.

柯立芝把住宿费和回学校的两张火车票价合计了一下.

The rate of rail creep lengthening is not the same at the different time after the new rail laying on the track.

得出新钢轨上道后的不同时期，其蠕变伸长速率是不同的。

The analysis shows that the active radial bogie can effectively reduce wheel/ rail wear, the wheel/ rail lateral force, derailment coefficient and wheel unloading rate.

结果表明，主动径向转向架可以有效地降低轮轨磨耗，对轮轨横向力、脱轨系数、轮重减载率等曲线通过性能有不同程度的改善。

The changing rate in each part of rail section size is more than 1.3% after cooling.

重轨冷却后各部分断面尺寸变化率都接近或超过了1.3%。

The rate of rail creep lengthening at the beginning after rail laying on the track is greater than that of the afterward time.

新钢轨上道后的前期，蠕变伸长速率较大，以后逐步降低。
