One theory involves the construction of a straight or spiral ramp that was raised as the construction proceeded.

一种理论是在建设过程中使用一条不断升高的笔直的或螺旋形斜坡。

But if the coupler's locomotive traction on the ramp is same as on the straight road, the axle load transfer will be a increase slightly.

但如果在坡道上机车承担的车钩牵引力与平直道的车钩牵引力相同，则轴重转移会有少量的增加。

Under the watchful, curious and excited eyes of the villagers, I pointed Miss Daisy's nose straight across the off-ramp and up the grassy hill.

在村民们好奇而兴奋的注视下，我将小黄的车头笔直指向驶入坡道和向上的草坡。
