摘　　要：传统的阻尼振动实验中,人们需要靠肉眼观测,用电子秒表记录半衰期,才能求出对数减缩等一系列关键数据.然而,肉眼观测和电子秒表记录必然带来较大的偶然误差.本实验中我们利用Phyphox深度传感器对整个阻尼振动过程进行测量,可以直接呈现振动物体的位移与时间关系图像,进而得到每个周期的振幅和半衰期的数据,该方法在一定程度上提高了实验精度.In the traditional damped vibration experiment,people need to observe with the naked eye and record the half-life with an electronic stopwatch to obtain a series of key data such as logarithmic reduction.However,naked eye observation and electronic stopwatch recording will inevitably bring large accidental errors.In this experiment,we use the Phyphox depth sensor to measure the whole damping vibration process,which can directly present the displacement and time relationship image of the vibrating object,and then obtain the amplitude and half-life data of each period.This method improves the accuracy of the experiment to a certain extent.
