I had to dismount and walk , maneuvering the bike on foot , up and down hills , on potentially ankle - breaking terrain 我不得不下车步行，边走边小心地推着车，在那随时都可能崴脚的地面上，上上下下地爬坡。
The electromotor power rating and the motor gear ratio to the drive wheels can then be determined based on the acceleration and gradeability 然后再通过加速或者爬坡的需要来确定电动机的额定功率以及电动机与驱动轮之间的传动比。
When cruising under low power demand conditions , the engine & motor will turn relatively slowly , while they will turn faster when accelerating or climbing a hill 在低功率条件下巡航时，发动机和电动机转速相对较慢，然而，加速和爬坡时，旋转快。
When the coach stops the hill repeats as just the right time , and the rider says , “ i could have done more , ” stopping is not a loss ? it ' s a victory 当教练在适当的时间停止爬坡训练时，而骑手却说“我可以再多骑一些” ，停止并不是一个损失-它是一项胜利。
For example , let ' s say you are training for a hilly , a - priority road race that is always won or lost on the last climb and one of your weaknesses is climbing 举例来说，你正为一个多山的优先级为a的公路赛而训练，这个比赛总是在最后一个爬坡段决出胜负，而你的弱项之一就是爬坡。
All the cross - river tunnels , slope climbing cableways , ferries and yachts peculiar to the city will continue to serve as a supplement to the city ' s public transport and will therefore play a very important role 城市中所特有的过江隧道、爬坡索道以及轮渡游艇，将继续作为公共交通的补充，发挥着积极重要的作用。
A hybrid vehicle can get by with a smaller internal - combustion engine than a conventional automobile because the battery and electric - motor system provides additional power when it is needed for acceleration or hill - climbing maneuvers 由于在需要加速或爬坡时，混合车的电池和电动马达系统可额外提供动力，因此混合车可以使用比传统汽车更小的内燃引擎。
Because a hybrid ' s battery and motor can provide the boost required for acceleration or hill climbing , engineers can both downsize the car ' s engine and optimize it to run only at high - efficiency operating points that burn much less gas 由于混合车的电池和马达可提供加速或爬坡所需的额外马力，因此工程师可以缩小引擎，设计让引擎只在耗油率最低的高效率运作点附近运转。
As a novel environment - protected vehicle , the middle and low speed maglev train has a large climbing gradient , small swerving radius , low noise , no pollution and can be compatible with any circumstances . it is the most competitive in the future city traffic 作为一种新型环保交通工具,中低速磁浮列车爬坡度大、转弯半径小、低噪声、无污染、对环境兼容能力强,在未来城市交通中具有较强的竞争力。
Arid regions in the southwestern have become increasingly inviting playgrounds for the growing number of recreation seekers who own vehicles such as motorcycles or powered trail bikes and indulge in hill - climbing contests or in caving new trails in the desert 美国西部的不毛之地正成为玩耍的地方，对越来越多拥有摩托车或越野单车类车辆的，喜欢放纵于爬坡比赛或开辟新的沙漠通道的寻欢作乐者具有不断增长的吸引力。
