摘　　要：通过金属导轨将小车的位移转换为电压信号,电压信号经微分放大处理后用DISLab电压传感器采集数据并计算,可得到小车运动过程中的各个时刻的瞬时速度。The metal guides can transform displacement into electric signals which can figure out the instantaneous velocity of every moment in the movement process after being enlarged and sorted out by differential and then being calculated the data collected through DISLab. The experiment shows the measured result is equal to the actual value.
