查询词典 aromatic hydrocarbon

Consider to think, although apparent gaseous state is not had in 0 derv of the interfuse in artesian well fluid,hydrocarbon exists, but fall in certain environmental temperature condition, the volatilization with have certain free hydrocarbon composition appears C_(11 the following liquid state volatilizes hydrocarbon , what cause gas to measure complete hydrocarbon thereby is unusual, but the change that this won't cause gas to measure constituent to be worth however, use this one characteristic, can lift with complete hydrocarbon and the method with not elevatory firedamp will distinguish the complete hydrocarbon holiday that mixes fluid of derv artesian well to cause is unusual.
