Methane
甲烷
Methane is the lightest hydrocarbon of the class called alkanes.
甲烷是烷烃类中最为轻的烃类
The first four alkanes are methane, ethane, propane, and butane with the Lewis symbols shown below.
前四个烷烃分别是甲烷、乙烷、丙烷和丁烷，其路易斯符号如下所示。
Methane is the major constituent of natural gas. It is lighter than air and very flamable. Both of those properties are shown in the images below which feature physics professor Clint Sprott of the University of Wisconsin in his "Wonders of Physics" demonstration show. Natural gas is passed through a bubble mixture to produce bubbles on the order of 10 cm in diameter. As these bubbles rise, he touches a lighted candle to one of them.
甲烷是天然气的主要成分。它比空气轻，而且极易燃烧。这两种性质在下面的图片中得到展示，这些图片展示了威斯康星大学物理学教授克林特·斯普罗特在“物理学奇观”演示中的实验。天然气通过一种气泡混合物被通入，产生直径约为10厘米的气泡。当这些气泡上升时，他将点燃的蜡烛触碰其中一个气泡。
