摘要
采用2种空气阻力模型,推导出考虑空气阻力时复摆振动周期的表达式.将理论结果与实验测量相结合,分析比较2种情况下空气阻力对复摆周期的影响.
The vibration period formulae for compound pendulum are deduced using two kinds of air resistance models. Combining with experimental results, the influences of two kinds of air resistance on the vibration period of compound pendulum are analyzed and compared.
