A turbulent combustion of hydrocarbon fuel-richgas with air two-dimensional supersonic shear flow was numerically simulated.
数值模拟碳氢富燃燃气与空气二维超声速剪切流动的湍流燃烧。

But in the fuel lean and fuelrich explosive gas, the electrical conductivity increases gradually from bottom to top.
贫燃料与富燃料爆炸气体中，由管道底部向上，其电导性是逐渐增大的。

The results show that the effects of speed on the exhaust gas emission and fuel economy are related with the ratio value and the absolute time of lean burn and rich burn.
