AZUZ: Finally today, ants -- the insects, not your mom`s sister. They`re strong, capable of lifting more than 100 times their own weight and banding together to drag relatively massive objects, like this unfortunate millipede. 最后,蚂蚁——一种昆虫,而不是你妈妈的妹妹。它们的力量非常强大,能够搬动比自己重100多倍的的东西,并且可以联合起来拖拽比较巨大的物体,像不幸的千足虫。 Well, researchers at Stanford University are trying to use micro-robots to mimic the super strong team work of ants. Working alone, they can move objects more than 2,000 times their own weight. Working together, they can move a car. 斯坦福大学研究人员正在尝试使用微型机器人来模拟蚂蚁的超强团队工作。一个微型机器人独自工作,可以拉动超过自身体重2000倍的物体。通过合作,它们可以移动一辆车。 This is three-and-a-half ounces of robots slowly moving 3,900 pounds of vehicle. 总重量为3.5盎司(99克)的6个微型机器人可以缓慢拉动重达3900磅(1769千克)的汽车。 A truly gargantuan feat though it moves at an almost stagnant pace. Of course, you could drive faster results by using a crank, but at 20 bucks a pop, the robots or ant, that is expensive. So, it`s really hard to say which is better. 虽然它们的移动速度很缓慢,但这是一个真正的壮举。当然,你可以通过使用曲柄使速度更快,但每个需要20美元,与蚂蚁相比,机器人更加昂贵。因此,真的很难说哪个更好。 We hope you`ll pull together to join us again tomorrow. 我们希望您明天继续齐心协力加入我们。 |
