摘　　要：三线摆用不同材质的摆线,会对实验结果产生不同程度的影响,摆线会出现共振。分别用鱼线和尼龙线作为摆线,对比忽略摆线伸长和考虑伸长,测量圆环和电木盘在不断增加质量情况下,周期和百分误差的变化。对实验结果进行分析。Three-wire pendulum with different materials of the cycloid,will have different degrees of impact on the experimental results.The cycloid will resonate.Using fishing line and nylon line as cycloid respectively,measure the variation of the period of vibration and percentage error of the rings and bakelite plate with increasing mass when the cycloid extension was ignored and considered.The results of the experiment were analyzed.

关 键 词：三线摆 摆线材质 振动周期 百分误差
