解释:

(n.) The act of turning, as a wheel or a solid body on its axis, as distinguished from the progressive motion of a revolving round another body or a distant point; thus, the daily turning of the earth on its axis is a rotation; its annual motion round the sun is a revolution.

(n.) Any return or succesion in a series.

(a.) Pertaining to, or resulting from, rotation; of the nature of, or characterized by, rotation; as, rotational velocity.
