从幻灯片上我们可以看到的图形，是关于利用模型的不同参数值阻尼α和虚拟质量δ，求出纸张快速运动的绝对误差的平均值。我们对参数α≥0和δ>0的不同值（上限为其最优值的两倍）进行了100次不同的模拟，并计算了运动最后7秒形成的测试窗口上的绝对误差（25）的平均值。被红色标记的是参数的最优值。实际上，最优值是一个全局最小值。

The graph we can see from the slide is about damping using different parameter values of the model α And virtual quality δ， The average value of the absolute error of the rapid movement of the paper is obtained. We're talking about parameters α ≥ 0 and δ> The different values of 0 (the upper limit is twice its optimal value) are simulated for 100 times, and the average value of the absolute error (25) on the test window formed in the last 7 seconds of the motion is calculated. What is marked in red is the optimal value of the parameter. In fact, the optimal value is a global minimum value.

We can see the figure on the slide, which is about using different parameter values of the model to damp α and virtual mass δ, and finding out the average absolute error of the rapid movement of paper. We simulated different values of parameters α≥0 and δ>0 for 100 different times (the upper limit is twice of their optimal values), and calculated the average value of absolute error (25) on the test window formed in the last 7 seconds of motion. What is marked in red is the optimal value of the parameter. Actually, the optimal value is a global minimum.
