摘要
严格推导了待测金属丝纵向振动频率与其杨氏模量的关系,并根据此测量原理，将光电光杠杆应用于拉伸法杨氏模量测量仪中，设计了一种高精度杨氏模量智能测量系统。
The relations between the longitudinal wave vibration frequency of a wire under given condition and it＇s Young＇s Modulus. According to this measuring principle, photo-electric optical lever is used in pulling and stretching measuring instrument to develop a high-accuracy intelligent system to measure Young＇s Modulus.
