Results show that the conversion rate of methane is mainly determined by plasma power and methane flow rate, the product selectivity is sensitive to reactor configuration.
结果表明：天然气在氮热等离子体中热解反应强烈，其转化率主要由输入功率和甲烷流量决定，产品的选择性亦即乙炔的收率与反应器的结构密切相关。
The result from the diagram analyse would be useful to determination of the possible location of spontaneous combustion and the possible direction of methane flow in the goaf.
图解的结果，对分析采空区内的瓦斯流动方向和可能发生自燃的位置是有益的。
Mr. Howarth included methane losses associated with flow-back and drill-out processes in hydraulic fracturing and other unconventional gas drilling techniques.
