The variation of combustion velocity, fired gas temperature and flame propagation speed, when the press, excess air ratio and ignition timing changed, was calculated by this quasi-dimensional model.

此模型能根据实测的燃烧压力曲线计算出层流燃烧速度、已燃气火焰温度及火焰传播速度等参数随压力、当量比、发动机转速、点火提前角的变化规律。

For the present experimental conditions, it is found that the flame propagation velocity is a weak function of dust concentration in cornstarch dust clouds.

在所考察的实验条件下，粉尘浓度对于玉米粉尘火焰传播速度的影响不大。
