So, instead of setting up the integral with bounds and integrating dx dy or dy dx or in polar coordinates, I'm just going to say, well, let's remember the definition of a center of mass.

那么我们将不会建立带上下限的积分，和积分dx, dy, dy, dx或者在极坐标做线积分，需要说，让我们回忆一下质心的定义。

Angular momentum for particles, separation of center-of-mass and relative coordinates, effective energy diagram.

微粒的角动量，质心分离以及相对坐标系，有效能量图。

Then obtaining the whole car dynamics parameters based on mass center coordinates formula of space force system and torque translation theorem.

再根据空间力系质心坐标公式和力矩平移定理求得整车的动力学参数。
