摘　　要：金割效应物理摆是用黄金分割法优选物理摆周期极值的自制仪器,摆的振动周期是重要的物理量,也是测量的主要参数。当存在空气阻尼、摆角过大或增加配重时都会使周期发生变化,只有把握好影响物理摆的振动周期的各种因素,才能保证测量结果的准确可靠,收到良好的效果。The golden section effect physical pendulum is a self made apparatus which uses the golden section method to search for the period extreme value, The vibration period of a physical pendulum is an important physical measurement, and also a main parameter of measuring When air resistance exists,the sway angle is too wide or weight is enhanced, the period will be affected. Provided that a variety of factors which affect the vibration period of the physical pendulum are ascertained, the reliability of the measurement result can be assured.
