观察自然频率对振动模态的影响（固定阻尼系数），可对有强迫振动项 的情形进行观察，将阻尼系数和自然频率固定，选择一种 的形式，观察 对振动模态的影响。
2、对由方程刻画的单自由度阻尼系统做动画仿真，观察阻尼系数，固有频率以及强迫振动项 对弹簧振动的影响，并和振动曲线图进行对比，写出你的观察结论。
-1、To observe the natural frequency of the vibration mode of (fixed damping coefficient), may have forced vibration of items to observe the situation, the damping coefficient and natural frequency is fixed, choose a form of observation of the impact of vibration mode.
2, characterized by the equation of a single degree of freedom to do animated simulation of damping system to observe the damping coefficient, natural frequency and vibration forced vibration of the impact of spring items, and to compare and vibration curve, write your observations conclusions.
