摘　　要：在枣庄学院物理实验室所用FD-HY-I型霍尔位置传感器法杨氏模量测定仪的基础上,改进为横梁劈尖干涉法测杨氏模量.运用劈尖干涉原理测量横梁下降的微小位移,提高了测量精度,同时将光学实验与力学实验有机结合,提高实验的综合设计程度.By replacing Hall position sensor method with wedge interference mthod to measure the Young＇s modulus based on our FD-HY-I measuring instrument,the measurement precision can be relatively improved by measuring the tiny position of the beam with the wedge interference mthod.The measurement mode is the combination of optical and mechanical modes,and improves the integrated design level of the traditional experiment.
