摘　　要：在“受迫振动与共振”实验中应用计算机进行测量,测定了无负载无阻尼音叉受迫振动的共振频率,振动曲线,品质因素;负载与振动频率的关系;有阻尼时的共振频率和品质因素.提高了本实验的精确度和效率.Through measuring with computer in the experiment of 'forced vibration and resonance vibration',some quantity has been mensurated,such as the frequency of resonance vibration,curve of vibration and quality in forced vibration without load and damp;relation between load and frequency of vibration;frequency of resonance vibration and quality with damp.It also improves the accuracy and the efficiency in this experiment.

关 键 词：受迫振动 共振 计算机 阻尼 品质因素
