Visitors to the museum look at the Wright brothers' small plane with its cloth wings, wooden controls and tiny engine.

游客们前往博物馆观看莱特兄弟的小飞机，飞机的布制机翼、木制控制杆和小小的引擎。

What began in the early 20th century as a humble canal boat puttering along with this tiny engine has since become giant container ships that stretch as long as skyscrapers stand tall.

20 世纪早期，小小的运河平底船用它的小引擎噗噗地前进，如今已经变成巨型的集装箱船，长度长达摩天大楼的高度。

Its ion thrusters put out less force than it takes to push a single key on a keyboard, but it accelerated to over 11 km per second by firing that tiny engine for nearly six years.

它的离子推进器产生的力比按下键盘上的一个键要小，但是通过点燃这个微型发动机将近六年，它加速到每秒 11 公里以上。
