查询词典 methane

From this perspective, flammable ice can be regarded as the natural gas in the highest purity, and you know, the general state of the natural gas, methane is only about 92% less, in addition to about 3% of the ethane, about 2% of the nitrogen and about 1% of the propane, as well as a very small amount of butane, pentane and oxygen and so on.

从这个角度说，可燃冰可算是自然中纯度最高的天然气了，要知道，一般状态下的天然气中，甲烷大约只占92%不到，此外还有3%左右的乙烷、2%左右的氮气和1%左右的丙烷，以及极少量的丁烷、戊烷和氧气等。
