| 释义 | 〔mill〕Tomill, in Western U.S. English, means "to halt a cattle stampede by turning the lead animals.”In theOxford English Dictionary we find this 19th-century example of the verb: "At last the cattle ran with less energy, and it was presently easy to ‘mill’ them into a circle and to turn them where it seemed most desirable" (Munsey's Magazine).This usage ofmill comes from the resemblance of the cattle's circular motion to the action of millstones. A related intransitive sense of the verb is better known in Standard English: A crowd milled around in the street. Originally this sense ofmill also meant "circular motion"; now it means "to move around in churning confusion"with no pattern in particular.Mill 这个词在美国西部所说的英语中， 意为“通过让领头牲畜绕圈子跑来制止牛群的惊跑”。在牛津英语词典 中， 我们可以找到该动词19世纪用法的例子： “最后牛群终于跑得快没劲儿了，这时候可以容易地驱赶头牛，把其它牛绕进圈子里，然后把它们赶到最合适的地方去” （芒西杂志）。Mill 的这种用法来自牛群绕圈跑与磨石运作的相似之处。 该词作不及物动词时所具有的与此相关的意义在标准英语中更为常见： 一群人在大街上兜圈子。 Mill 的这一含义本来亦指“旋转运动”； 现在它指“在旋涡般的混乱中到处移动”，不再有其它特指〔pivot〕The act of turning on or as if on a pivot.转动，旋转运动：在枢轴上或似乎在枢轴上转动的行为〔boomerang〕The words we have borrowed from native languages of Australia,such asbillabong, budgerigar, dingo, kangaroo, koala, kookaburra, waddy, and wallaby, generally have the exotic sound of down under, andboomerang is no exception. In a book about the languages of New South Wales published in 1790 is found the native termboo-mer-rit, glossed "the scimitar,” because of the curved shape of the boomerang.In 1825 in a passage containing the first recorded instance of the English formboomerang we are told it is "a short crested weapon which the natives of Port Jackson [now part of Sydney] project with accurate aim into a rotary motion.”In 1827 another commentator says that this term "may be retained for want of a more descriptive name.”我们从澳大利亚本土语言借来的单词，比如billabong（死水潭），budgerigar（虎皮鹦鹉），dingo（骗子），kangaroo（袋鼠），koala（树袋熊），kookaburra（笑翠鸟），waddy（木棍） 以及 wallaby（沙袋鼠） 等， 一般都有来自异国的声音，boomerang 也不例外。 1790年出版的一本关于新南威尔士的语言的书中有个本土词汇boo-mer-rit， 意为“偃月刀”，是因为其回飞镖的弯形。在1825年的一篇短文中有boomerang 的英语形式的最早记录， 我们被告知那是“一种杰克森港［今悉尼的一部分］土著设计的带有饰章的短武器，能在旋转运动中精确击中目标。”1827年另一位评论者说这个词汇“由于缺少一个更富描述性的名字可以保留”〔pallet〕A projection on a machine part, such as a pawl for controlling the motion of a ratchet wheel in a watch escapement, that engages the teeth of a ratchet wheel to convert reciprocating motion to rotary motion or vice versa.棘爪：机器部件上的一个突出部分，例如在一个观察棘轮装置中控制棘轮运转的棘爪，用来衔接棘轮的齿，以将往复运动转换为旋转运动；反之亦然〔revolution〕A turning or rotational motion about an axis.旋转：围绕一轴的转动或旋转运动〔Kovalevsky〕Russian mathematician known for her work on partial differential equations and equations of rotatory motion.科瓦列夫斯基，索雅：(1850-1891) 俄国数学家，以她对微积分方程和旋转运动方程的研究而出名 |
