The second, the flame shape and color were determined by the concentration gradient of the place near the igniting position.

其次，火焰的形状和火焰的颜色是由点火位置附近的浓度梯度决定的。

The numerical simulation results indicate that the flow of fuel and air varies with different structures, and as the result is the difference of flame shape and temperature distribution.

数值计算结果表明，结构差异是燃料气和助燃空气的流场组织不同的原因，表现为不同的燃烧火焰形状及温度分布。
