| 摘 要： | 杨氏模量测定实验的关键是对钢丝微小伸长量的测量,利用差动电容传感器将微小伸长量变换为电量,研究得出,微小伸长量与电路输出的电压成线性关系,利用模拟实验,测出理论计算与实验数据之间符合的非常好,这种测量方法还可以利用计算机对数据进行处理。

| Abstract: | The key of Young's modulus experiment is the diagraph which measures to the steel wire small elongation,we make use of differential capacitive sensor to measure small elongation the transformation measure for the electricity,we find small elongation quatity and electric circuit output's electric voltage become line sexual behavior,Using simulation experiment,which find out theories calculation and experment data match of very good,this kind of diapraph method can also make use of calculator logarithms according to carry on a processing. |
