温特森是英国皇家艺术学院的硕士生,来自伦敦郊区的乡下。他的父亲经营一个小型牧场,饲养着几百上千头奶牛。他很讨厌去牧场,因为牛屁的气味让人难以忍受。牛屁的气味为什么这么臭,牛屁到底是一种什么气体呢?它是怎样形成的?在好奇心的驱使下,温特森上网查阅了资料。原来,牛屁中含有一百多种混合气体,但最主要的是甲烷气体。奶牛吃了大量青草和苜蓿等植物,经过胃的消化和反刍过程,会产生大量的甲烷等气体,然后通过牛屁排放出来。温特森知道,天然气的主要成分就是甲烷,现在很多汽车

Winterson knows that the main component of natural gas is methane, and now a lot of cars
