摘要: 针对简谐振动实验数据处理存在的问题进行分析,提出以t到t+Δt的平均速度表示t+Δt/2时刻的瞬时速度而不是t时刻的瞬时速度,利用多项式最小二乘法拟合实验数据得到与理论计算相吻合的振动曲线.

关键词: 简谐振动, 误差分析

Abstract: Using the average speed from t to t+Δt to express the instantaneous velocity at t+Δt/2 rather than t is proposed for the experimental data processing of the problem of simple harmonic analysis.Polynomial least-squares fitting of experimental data obtained is consistent with the theoretical calculation of the vibration curve.

Key words: simple harmonic vibration, error analysis
