摘要
从动态杨氏模量实验共振基频存在系统误差入手,认为产生这种误差的原因,是由理论上杆的自由横振动模型和实验上具有某种约束条件的小阻尼受迫振动模型之间差异造成的。
The systemic error of the resonance base frequency existing in dynamic Young module's experiment is analyzed, and the cause of this type error is found that resulting from the difference between the theoretical model and the experimental restraint conditions.
