摘　　要：针对教材中简谐振动的DIS探究实验的不足,对实验进行了改进.首先,用小车做弹簧振子,并利用滑轮连接砝码,以减小摩擦力,同时以静止时小车的状态为平衡态,以解决弹簧被压缩变形的问题,实验还通过DIS实验系统采集数据,由此可以得到各个物理量间的关系.The DIS exploring experiment of simple harmonic oscillation in teaching material is improved. Firstly, in order to decrease the friction, the author uses vehicle as the spring oscillator, and uses pulley to link weights. Secondly, to resolve the problem of spring deformation, the author uses the vehicle at rest as an equilibrium reference, and uses DIS experiment system to collect data, and then the relation of physical quantity is obtained.
