   min是时间单位,是分钟(minute)的前三个字母。 有关时间的缩写:yr表示:年份;h或hr表示小时;s或sec表示秒。 常用时间单位还有: 小时:h 秒:s 拓展资料 时间单位,是7种基本单位之一,长度、时间、质量、物质的量、光照度、电流 和(热力学)温度 是七种基本单位。 本词条中时间单位以时间从大到小列。 现时每昼夜为二十四小时,在古时则为十二个时辰。当年西方机械钟表传入中国,人们将中西时点,分别称为“大时”和“小时”。随着钟表的普及,人们将“大时”忘淡,而“小时”沿用至今。 min是minute的缩写,意思为分钟或者是最小值。min在数学学科里面,是指在一个区间内最小数。例如Fmin≤F≤Fmax。min还主要用在数学表达式的单位中,是分钟的单位。 min是minute的缩写,意思为分钟或者是最小值。min在数学学科里面,是指在一个区间内最小数。例如Fmin≤F≤Fmax。min还主要用在数学表达式的单位中,是分钟的单位。 min是指分钟。不用说了不用说了,就是指分钟。 时间单位 s表示秒,min表示分钟,h表示小时 如果您满意我的回答,请及时点击【为满意回答】按钮!!! 提问的朋友在客户端右上角评价点【满意】即可!!! 你的是我前进的动力!!! !!! 时间单位,是minute的简写 ,也就是分钟,一般用在切削参数的单位里,如rad/min 多少转每分钟 、 mm/min多少毫米每分钟

3、when the street lights go on at dusk,翻译

   黄昏时,华灯初上,一幅美丽的画卷呈现在眼前。 go on 本意是继续的意思,是一个动词短语。但在这个句子里是go是动词,on是形容词,形容灯亮了。go与on之间稍有停顿。 试体会:(1)I go on learning English late at night. (2)to go/on strike(去罢工)go=去 on strike=罢工中 make a picture 动宾短语。make翻译成“构成”比较好,构成一幅画卷。 原句是灯做主语,我用画卷做主语,更体现用中文描述景物的手法,这样的翻译法在翻译实务中常常使用,请楼主自己体会灯做主语和画做主语的细差别 回答者: 白色闪电琪 见习魔法师 二级 : 这位翻译得比较好,语法也讲解得不错. 黄昏时刻,渐渐亮起的街灯让这个城市与白天截然不同,俨然一副美丽的图画 黄昏时分,街灯亮起,构成一幅美丽的图画。 go on 在这里和be on 的用法一样,只不过前者更强调动作意义,后者则表状态,如,“房间里的灯一直亮了三个小时。” 可以翻译为:The light in the room has been on for three hours. make a picture中make就是构成,成为
