摘要
吉林大学无机合成与制备化学国家重点实验以美国QD公司出产的超导量子干涉仪SQUID-MPM3系统为基础,外接小型测试仪表,建立可在低温强磁环境下进行电输运、光电输运等电学性质测试的多功能测试平台,并利用LabVIEW13语言为其搭建了虚拟测试平台。此虚拟测试平台利用National Instruments公司提供的QDinstrument_labview.zip软件包中SQUID-MPM3系统控温、控场等模块为基础,嵌入外加测试仪表的控制和数据采集模块,设计能实时采集和处理数据的高精度材料电输运、光电输运测试软件系统,直观显示出材料在超低温度变化区间和外磁强场条件下的电输运特性图,并实时保存测试数据。
Based on the superconducting quantum interferometer SQUID-MPM3 system produced by QD Company in United States,a multifunctional platform is built for testing the properties of electric transport and photoelectric transmission under the conditions of low-temperature and strong magnetic environment by adding a small-scale instrument in State Key Laboratory of Inorganic Synthesis and Preparative Chemistry in Jilin University.Moreover,a virtual test platform is also built by using the language of LabView 13.This test platform is developed based on temperature control and control field modules from the SQUID-MPM3 system in the QDinstrument_labview.zip software package provided by National Instruments Inc.It is embedded with the control from the external test instrument and data acquisition module,which is designed to collect and deal with data in real time.The software test system for electrical transport and optoelectronic transport of high-precision materials will visually display the characteristic patterns of electrical transport under the conditions of ultra-low temperature and external magnetic field and save testing data in real time.
