摘    要:测量铁电材料的电滞同线是确定铁电参数、检验材料性能好坏的一个重要手段,目前采用的主要测量手段是示波器法。但是,这种传统的方法无法在测量的过程中对误差进行修正、对数据进行处理和分析。为了克服这种不足,研究和开发了一种基于美国NI公司最新推出的LabVIEW7.1Express虚拟仪器开发平台的电滞回线测试系统,通过介绍该系统的数据接口、数据处理、数据库链接以及多种语言联合作业的方法,提出了一种新的电滞回线测量方案,并获得了初步的实验结果。

关 键 词:电滞回线  数据采集  虚拟仪器

Abstract:Measurement of hystersis in ferroelectrics is very important in determination of their physical parameters and material performance.The main method which is currently available in hystersis measurement is oscilloscope.However,this type of method cannot correct,process and analyse the data measured.In order to overcome these porblems,a hysteresis measuring system was based on LabVIEW 7.1 Express virtual instrumentation.The data input,data processing,and data connection as well as the combined work in multiple languages of the system were introduced.The new design of measuring system was carried out and the preliminary experimental results were obtained.
Keywords:LabVIEW
