1.Maybe the sun is spinning down, is slowing down and maybe the energy that we get is nothing but rotational kinetic energy.
也许太阳转速正减慢，也许我们得到的能量，不是别的，而是旋转动能。
2.When solitude occupies my whole mind, even the rotational speed of a second hand turns into a sluggish wriggle.
当孤独占据了我的全部时，就连秒钟的转速也成了一种慵懒的蠕动。
3.The wind passing over the blades forces them to turn which in turn converts the rotational energy through a gearbox into electricity.
风越过叶片，迫使它们把这反过来又转换为旋转能量通过变速箱转化为电能。
4.Since the Earth's rotational axis is tilted, the Sun is directly over the equator just twice a year.
因为地球的自转轴是倾斜的，因此一年当中太阳光只有两次机会直射赤道。
5.I will first discuss with you the sun and the earth and see how much rotational kinetic energy is stored in the earth and in the sun.
首先讨论太阳，然后是地球，看看地球和太阳中，具有多少旋转动能。
6.Knowing the state of the rotational motion of a system, determine the external forces or external torques acting on the system.
已知质点系的转动运动，求系统所受的外力或外力矩。
7.One way to see this is to compare the energy of a nuclear blast to that of the rotational motion of the Earth.
有一种方法可以说清楚这个问题：即把核爆炸的能量与地球转动的能量作一次比较。
8.Some of this rotational energy also pours to the aurora of earth upon a recurring basis from all points upon the surface of the earth.
某部分此类能量也倾泻到地球的极光中，基于重现在地球表面的每点上出现。
9.If I know the moment of inertia, then I know how much rotational kinetic energy there is.
若知道转动惯量我就能知道，转动动能是多少。
10.I came to understand scoliosis as having a complex rotational dynamic, arising out of a growth process, albeit one that has gone awry .
我开始理解脊柱侧凸是一种复杂的转动动力，源于生长过程那块早已弯曲的骨头。
