real displacements of the rotational axis of the earth in space, and until Newton came and, combining his discovery of universal gravitation with his deduction of the ellipsoidal figure of the earth, proved that these displacements are due to the actions of the moon and the sun on the earth....
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。 article.yeeyan.org 2. This measurement of the year depends on the direction of the Earth's rotational axis, which unfortunate...

This chapter discusses the absolute displacement with respect to the earth's rotational axis. Several methods measure absolute displacements in latitude and orientation with respect to geographic north to supplement the information from plate tectonics for reconstructing the geographic position of the contine...
Finally, Earth´s unique and massive satellite, the Moon, plays a crucial role in stabilizing the obliquity of Earth´srotationalaxis. 最后,月球作为地球独特而巨大的卫星,在稳定地球旋转轴的倾角方面发挥了关键作用。 4. For an object to be inrotationalequilibrium about a certain point, the total...
