It is proved that the fundamental diagram of the average traffic flow speed as the function of the car density for the new model is exactly the same as for fi model.

证明新模型的基本图，即车流渐近稳态的平均速度与道路上的车辆密度之间的函数关系与FI模型的完全相同。

In the similarity analysis of floods, the extension model is developed which takes the average water level and average flow of key stations as two characteristic indices.

场次洪水的相似性分析中，以时段内流域主控站平均流量和平均水位作为特征指标建立可拓评判模型。

This model takes into account the difference of average velocities between gas-phase and liquid-phase, which overcomes the defect of mean-phase flow model.

这一模型考虑了各相平均速度之间的差异，克服了以往均相流动模型的缺点。
