   9月16日是墨西哥馆日,墨西哥馆五颜六色的“风筝森林”吸引了不少人的眼球,你知道小小的风筝里有什么大学问吗?其实风筝也有很多种分类哦,一起来看看吧。


  说到kite这个单词,这也许是我们刚开始学英语的时候就学到的吧,现在看来好有亲切感呐。大家印象中的风筝是不是就是那种蝴蝶形状,拖着一根线的东东?记不记得在游乐场或者学校开运动会的时候,有那种五颜六色、或者做成不同动物形状的大气球,一动不动浮在空中?其实,那也是一种kite:
  Kites are usually heavier-than-air, but there is a second category of lighter-than-air kite called a kytoon which may be filled with hydrogen, hot air, methane 1, or helium; these stay aloft with or without wind.
  风筝通常比空气重,但是有一种比空气轻的风筝,叫做风筝气球,以氢气、热空气、甲烷或者氦气填充,不论有风没风都会浮在空中。
  其实kytoon这个名字就是由kite+balloon形成的,所以这种kytoon还是属于风筝的范畴哦。
  风筝除了供孩子们嬉戏玩耍,还是一种竞技体育哦,有新型的雪地风筝,snowkiting,利用风筝的动力来滑雪;同理利用风筝提供的动力进行冲浪的运动,就叫做kitesurfing;甚至有用风筝协助滑板运动的,这种叫做kite landboarding,这些利用风筝提供动力的运动,所需要的都是特制的大风筝,power kite,依据的也就是aerodynamics,空气动力学的原理。
  怎么样?不要小看风筝哦,还是可以玩出很多稀奇古怪的花样的。

n.甲烷,沼气
  • The blast was caused by pockets of methane gas that ignited.爆炸是由数袋甲烷气体着火引起的。
