Most people usually traveled by ship and train which are driven by steam engine. It played an important part in many kinds of vehicles several scores of years ago. Who invented steam engine and what units could be used to measure the power of engine？
The word “horse-power” was first used two hundred years ago. James Watt from a worker’s family made the world first widely used steam engine. At first, he couldn’t tell people how powerful it was, because there were no units at that time. Watt decided to find out how much work one strong horse could do in one minute. He named that unit one horse-power. In this way he could measure the work of his steam engine.
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 horse-power engine.

很多人选择轮船及火车作为出游工具，它们均以蒸汽发动机作为引擎。数十年前，蒸汽发动机在轮制机器方面占有重要地位。那么，是谁发明了蒸汽发动机？又是什么组合能用来衡量这种能量？
两百年前，“马力”一词首次被采用。工人家庭出身的詹姆斯·瓦特，首次将“马力”一词广泛运用到蒸汽发动机。首先，由于在当时没有量度来表示机能， 他无法向世人阐述机器的动力值。瓦特决定找出一匹强壮的马在一分钟工作量，并将此命名为“一马力”。用这种方式，他衡量了蒸汽机的工作量。
他发现，一匹马一分钟内能将3300磅的物体拉起10英尺。他的发动机能在一分钟内将3300磅重的物体抬高100英尺。因为他的发动机的工作能量是一匹马的十倍，所以瓦特将发动机命为10马力。
