事实上在那一点存在一个侧向的加速度，即使它的速率没改变。

And, in fact, there is a sideways acceleration at that point even though the speed is not changing.

该方法采用主动转向技术来改变转向轮的转向角度，有效地减少了汽车的侧向加速度，提高了汽车的防侧翻的能力。

The strategy adopts the active steering technique to change the wheel steering Angle, and hence can reduce the lateral acceleration and improve the anti-rollover ability of vehicles.

在轴向和侧向两个方向上存在明显的各向异性，侧向能更快速和灵敏的反映应力变化引起的流变特性的改变；

Obvious anisotropy exists both in axial and lateral direction, and the phenomenon on the lateral can be more rapid and sensitive to reflect the rheological properties caused by the stress changes.
