摘　　要：利用Tracker视频软件的自动追踪功能,有效地跟踪气垫导轨上弹簧振子的阻尼振动,实时描绘出振动的位移-时间曲线,利用软件自带的功能拟合出振动曲线方程和包络线方程,计算出该气垫导轨的阻尼常数,并由坐标转换功能得到运动的相图.By the automatic tracking function of the software Tracker, the damped vibration of spring oscillator has been tracked effectively. The displacement-time curve is depicted in the real time. The vibration equation and envelope equation are fitted by the fitting function of the software. The damping coefficient of air track is calculated. The phase diagram can be obtained by the function of coordinate transformation.
