这有一个例子，可以说明角冲量和角动量概念的用途。

Here is an example of the usefulness of the concepts of angular impulse and angular momentum.

着重探讨了来流攻角和扰流片高度对过冲量的影响。

As a primary purpose, the effect of Angle of attack and height of spoiler on the unsteady flows are investigated.

结果表明：当锥角固定时，冲量和冲量耦合系数随无量纲因子先增大后减小，极大值对应的无量纲因子仅与气体比热比相关；

The results show that, impulse and impulse coupling coefficient firstly increase and then decrease with the augment of the dimensionless factor when cone angle is fixed;
