摘要
通过金属线膨胀系数测定实验与光纤传感器实验中的测量技术相结合,设计并改善了对金属线膨胀系数的测量方法。首先介绍了金属线膨胀系数和光纤传感器的研究概况,提出自己的设计理论,推出基于光纤传感器的金属线膨胀系数测定的公式。通过实验验证并利用Mat Lab中的Basic Fitting对数据进行优化处理得到比较精确的金属线膨胀系数。
This text spreads a feeling machine diagraph technique within experiment to combine together and designs according to metal line coefficient of expansion measurement experiment and the fiber optic and improved the diagraph to metal line coefficient of expansion.Introduced metal line coefficient of expansion and fiber optic to spread the research general situation of feeling machine first,then put forward own design theory,release the formula that spreads metal line coefficient of expansion measurement of the feeling machine according to the fiber optic.Pass an experiment verification and make use of the Basic Fitting logarithms in the MATLAB according to carry on excellent turn a processing to get more accurate metal line coefficient of expansion.
