英语翻译
The word horsepower (马力) was first used two hundred years ago .James Watt had made the world’s first widely used steam engine (蒸气机) .He had no way of telling people exactly how powerful it was ,for at that time there were no units for measuring (测量)power .
Watt decided to find out how much work one strong horse could do in one minute .He called that unit one horsepower .With this unit he could measure the work his steam engine could do .
He discovered that a horse could lift a 3300-pound weight 10 feet into the air in one minute .His engine could lift a 3300-pound weight 100 feet in one minute .
Because his engine did ten times as much work as the horse ,Watt called it a ten horsepower engine .

马力这个词在200多年前已经被首次使用了.詹姆斯•瓦特已经制造出世界上第一台广泛使用的蒸汽机.然而,他不能清楚的告诉人们蒸汽机能够产生多大的功率,因为当时没有衡量功率的单位.
瓦特决定看看健壮的马匹能够在一分钟内做功多少.之后他称之为一马力.有了这样的单位,就可以测量出他的蒸汽机产生的功率了.
他发现一匹马可以在一分钟的时间里将3300磅的物体升高10英尺,而他的蒸汽机在相同的时间里将同样重的物体升高100英尺.
由于他的蒸汽机可以产生十倍于一匹马所产生的功率,所以瓦特称其为10马力机车.
