The use of the word is analogous to its use in verse, with its traditional metrical units of iambus, trochee, dactyl and so on. 节拍在此处的用途与其在诗文中长音节的抑扬短长等作用相似。
In poetic meter, a trochee/ˈtroʊkiː/, choree, or choreus, is a metrical foot consisting of a stressed syllable followed by an unstressed one, in English, or a heavy syllable followed by a light one in Latin or Greek. In this respect, a trochee is the reverse of an iamb.
