分钟用英语怎么说?

小时的英文单词为:hour,符号为:h分钟的英文单词为:minute,符号为:min秒的英文单词为:second,符号为: s1、小时是时间单位。小时不是时间的国际基本单位,而是一种辅助时间单位。在英文或数学中常用“h"表示。2、分又称作分钟,也是时间单位。分的英语是minute,是“微小”的意思,也表示min。3、秒是国际单位制中时间的基本单位,符号是s。有时也会借用英文缩写标示为sec.。扩展资料:小时、分钟、秒之间的换算:1小时hr(h)=60分钟min(m)=3600秒sec(s)国际单位制词头经常与秒结合以做更细微的划分,例如ms(毫秒,千分之一秒)、us(微秒,百万分之一秒)和ns(纳秒,十亿分之一秒)。虽然国际单位制词头虽然也可以用于扩增时间,例如ks(千秒)、Ms(百万秒)和Gs(十亿秒),但实际上很少这样子使用,大家都还是习惯用60进制的分、时和24进制的日做为秒的扩充。1、毫秒毫秒是一种较为微小的时间单位,是一秒的千分之一(0.001秒),简称ms。典型照相机的最短曝光时间为一毫秒。一只家蝇每三毫秒扇一次翅膀;蚊子二十毫秒振翅一次;蜜蜂则每五毫秒扇一次。由于月亮绕地球的轨道逐渐变宽,它绕一圈所需的时间每年长两毫秒。在计算机科学中,10毫秒的间隔称为一个jiffy。2、微秒微秒(microsecond)即百万分之一秒(10的负6次秒),简称μs。光在这个时间里可以传播300米,大约是3个足球场的长度,但是海平面上的声波只能传播1/3毫米。高速的商业频闪仪闪烁一次大约持续1微秒。一筒炸药在它的引信烧完之后大约24微秒开始爆炸。3、纳秒纳秒(nanosecond)即一秒的10亿分之一(10的负9次秒),简称ns。常用作内存读写速度的单位。光在真空中一纳秒仅传播30厘米(不足一个步长)。个人电脑的微处理器执行一道指令(如将两数相加)约需2至4纳秒。另一种罕见的亚原子粒子K介子的存在时间为12纳秒。参考资料:百度百科-时间单位百度百科-分钟百度百科-小时

问题五:三十秒的英语诗歌 If you think you are beaten, you are;
If you think you dare not, you don't;
If you want to win but think you can't;
It's almost a cinch you won't.
If you think you'll lose, you're lost;
For out of the world we find
Success begins with a fellow's will;
It's all in a state of mind.
Life's battles don't always go
To the stronger and faster man,
But sooner or later the man who wins
Is the man who thinks he can.
如果你认为你败了,那你就一败涂地;
如果你认为你不敢,那你就会退缩畏葸;
如果你想赢但是认为你不能;
那么毫无疑问你就会失利。
如果你认为你输了,你就输了;
因为我们发现人世间
成功从一个人的意志开始;
成功是一种心态。
生活之战中,
胜利并非总是属于更强和更快的人,
胜利者终究是
认为自己能行的人。
