To avoid potential human casualties and environmental pollution,flowout gas from sulphuric gas wells showing high concentrations of volatile gas must be neutralized by controlled ignition.Simulation model is built by using CFD software for flowout gas,and ignition methods are analyzed.The simulation results indicate that the optimal ignition zone is located between 150 mm and 570 mm above the gas flowout device.Two ignition methods,electronical and chemical,are developed.12 and 6 experimental tests are performed respectively for these two methods.Results from the above tests verify that both approaches are successful in igniting the gas promptly and safely.In addition,our experience proves that the former way is more suitable for the fixed position ignition case,while the latter is more suitable for the long-distance or emergent ignition case.These two approaches can potentially be applied to a wide range of situations other than the fixed position ignition case and long distance ignition case.

要成功地带领人民实现现代化,需要进一步改善党和政府的领导和执政方式。 今年是中共建党90周年,执政61年。中共从90年前一个只有10几个党员的小党,发展到如今拥有7000多万党员、管理着一个13亿人口的发展中大国的世界第一大党,是几代共产党人前赴后继、筚路蓝缕开拓和创新、奉献和牺牲的结果。 其间有胜利的喜悦,也有失误的惨痛。但不管怎样,中共在90年的历史中不断发展壮大的事实本身,就足以证明
