吹氩形成的微气泡群可以显著改善中间包内流体的运动轨迹，流体运动的路线更加曲折，并且全程流动靠近液体表面。

Because, the movement track of liquid steel is improved by the argon bubbling and route of fluid flow is much more flexuous and close to the bath surface.

这一模型可以用来仿真驾驶员在操纵汽车的过程中，根据前方道路交通的可行区域，决策汽车未来期望走行轨迹的控制行为特性，并可描述驾驶安全程度、驾驶员体能极限等诸多指标。

The model can simulate the driver′s control behavior of deciding the vehicle preview course in the process of driver′s handling the vehicle, based on the feasible region of front road.
