1·Do not confuse ever the tangential acceleration, which is along the circumference, with centripetal acceleration.

不要把沿圆周的切向加速度与向心加速度混淆。

2·Do not confuse ever the tangential acceleration, which is along the circumference, with a centripetal acceleration.

但是别把这个切向加速度，它是沿着圆周的，和向心加速度混淆。

3·An analytical solution is presented to compute the state transfer function when both normal and tangential acceleration are constant. This model can give a better priori acceleration estimation.

该方法把切向加速度和法向加速度作为状态变量，给出了切向加速度和法向加速度为常值时解析计算状态转移的方法。
