谁给我翻一下 谢谢!
Take an any long piece of paper. Now glue(粘) the ends of the paper together. You have made a ring.
Take a second long piece of paper. Twist(扭转) the paper once and glue the ends together. Now you have made a Moby’s band(带子). For people studying maths, this band is uncommon.
This strange band was first made in the 1800s by a German named August Moby’s. Mr. Moby’s studied maths. He wanted to find a way to show how this band works with maths. Believe it or not, this band has only one surface. You can find this out for yourself.
If you draw a line on the surface of the paper before you twist and glue it, the line is only on one side of the paper. The paper has two surfaces. However, if you draw a line after you make the Moby’s band, you can follow the line around all sides of the paper. In other words, the Moby’s band must have only one surface.
It is also very interesting to see what happens when you cut the band. If you cut the Moby’s band in half once down the line you drew, you do not get two Moby’s bands. Instead, after you cut the band, it turns into one large twisted ring. Then, if you cut this ring in half along the middle of the band again, you get two connected Moby’s bands. Try it!
那个带子是怎么粘的啊?
最好全翻译过来哦!
翻译
任取一条纸,把纸的两端粘合在一起,你就做成一个纸环.
再拿第二张长纸条,把纸条扭转一次然后把两端粘在一起,你就会做成一个莫比纸带.对研究数学的人而言,这种带子是不同寻常的.
这种不为人所知的带子是由一个名叫奥格斯特•莫比(August Moby)的德国人第一次做成的.莫比先生研究数学.他想找到一种方法去表明如何把这种带子与数学联系在一起.信与不信由你,这种带子仅有一个面,你可以自己动手发现这一点.
在扭转纸条并粘合起来之前如果你在纸的表面画一条线,这条线只在纸的一面.一张纸有两个面,但是假如你在做成莫比纸带以后再画线,那么你就会沿着这条线转遍纸带所有的侧面,换言之,莫比纸带仅有一个表面.
同样有趣的是,当你剪断纸带时就会看到所发生了什么现象.如果把莫比纸带沿着你画出的线环剪为两半,你却不会得到两个莫比纸带.相反,剪断以后,它却变成了一个大的螺旋状环.假如你再把这个大环第二次沿着纸带的中间剪为两半,你就会得到两个连接在一起的莫比纸带.试试看吧!
