Question

The first spring-powered clock was invented by Peter Henlein of Germany around 1510. The power for this clock came from a metal coil inside called a mainspring.To operate the clock, a person would wind the spring by turning a key. As the spring wound, it moved the hands of the clock. This was more accurate, but there was a problem; as the spring unwound, the hands of the clock moved slower, and the clock lost time.

Answer 1

世界上第一只发条钟是在1510年由德国人彼得亨利发明的.这只钟的动力由叫做发条的内置金属线圈提供.人们通过旋动发条键给发条上劲,这样绷紧的发条就能使指针转动.这种方法计时更加准确,但也有一个问题;就是随着发条伸展开来,指针走动减慢,时钟计时就会变慢.

Answer 2

声明我不是英语专业，也不是用Google弄的：
德国的Peter Henlein 在1510年左右发明了历史上第一个以发条为动力的钟。钟的动力来源于一个叫做主发条的金属螺旋弹簧。操作这种钟表的时候，得有一个人以转动一个钥匙的方式带动弹簧。当发条工作时，它可以带动指针的转动。这种钟更精确，但是存在一个问题，就 当发条不紧了的时候，指针运动变慢，也就使指示的时间变慢了。
