At last, the paper analyzes the kinematics of the Ice-skater Robot when it turns and skates forwards respectively.
最后,以溜冰机器人为例分析了其转弯和直线滑行时的运动学问题。
A typical exam question went something like this: an ice-skater weighs 150 pounds and is doing figure-eights on ice an inch thick.
举个典型的例子,有个问题是这样的:一个溜冰者,体重150磅,在一英寸厚的冰面上划“8”字形溜冰。
The general low level of friction on ice allows a skater to glide along the surface smoothly without friction stopping the motion as soon as it´s begun.
冰面上摩擦力通常较低,这使得滑冰选手一俟启动,就能不受摩擦力牵绊,顺畅滑翔冰面。
Since that pulls mass closer to the planet´s spin axis, it causes the planet to rotate faster - just as an ice skater spins faster when she pulls her arms towards her body.
由于质量朝地球旋转轴靠拢,这就导致地球旋转速度加快- - -就像一个速度滑冰选手,当她把胳膊向身体收拢时就会旋转得更快。
Ranked third in the world in May 2010, 19-year-old Asada is Japan´s top ice skater.
2010年3月的世界排名第三,使19岁的浅田真央成了日本最好的花滑选手。
