oscillate的注释：

7. The rather dry word oscillate may become a bit less dry as we learn its story. It is possible that it goes back to the Latin word ?scillum, a diminutive of ?s, “mouth,” meaning “small mouth.” In a passage in the Georgics, Virgil applies the word to a small mask of Bacchus hung from trees to move back and forth in the breeze. From this word ?scillum may have come another word ?scillum, meaning “something, such as a swing, that moves up and down or back and forth.” And this ?scillum was the source of the verb ?scill3re, “to ride in a swing,” and the noun (from the verb) ?scill3tio, “the action of swinging or oscillating.” The words have given us, respectively, our verb oscillate, first recorded in 1726, and our noun oscillation, first recorded in 1658. The next time one sees something oscillating, one might think of that small mask of Bacchus swinging from a pine tree in the Roman countryside.
当我们了解了与oscillate 有关的传说时，这个较为枯燥的词就会变得不那么干巴巴的了。 此词可被追溯到一个拉丁词oscillum， 可简写成os， “嘴”，意为“小嘴”。 在农事诗集 的一节中， 维吉尔用这个词指挂在树上在微风中来回摆动的酒神巴克斯的小假面具。从oscillum 一词可以得出另一词 oscillum， 指“前后或上下摆动的某物，如秋千。”而这里的oscillum 便是意为“在秋千上摆动”的动词 oscillare 和意为“摆动或摇动的动作”的名词（从动词来） oscillatio 的词源。 从这些单词中分别得出了我们今天所用的动词oscillation （首次记录于1726年）和名词 oscillation （首次记录于1658年）。 以后若看见物体在摆动，就很可能会想起古罗马乡间一棵松树上摇来晃去的巴克斯的小假面具了
