基于虚拟仪器平台的导热系数测定仪的设计

The Design of Thermal Conductivity Coefficient Surveying Instrument based on Virtual Instrument Platform

作者依据无限大平板导热理论的傅立叶导热定律设计了平板式导热系数测定仪。由于选择了虚拟仪器平台 ,使得整机成为一套全自动化的测控仪器 ;由于选择了图形化微机语言 ,极大降低了底层程序编制的工作量。文中给出了仪器测试结果 ,指出没有先进的计算机技术 ,复杂的测控系统是难以实现的。

According to the Fourier thermal conductivity theory for infinite plate,the authors design a tabulate thermal conductivity coefficient surveying instrument.It becomes a set of automatic measure and control in- strument for the use of virtual instrument.Workload of bottom- program is reduced for the use of graph pro- gram language. The experimentresultis given. The authors also pointoutthatwithout the advanced computer technology it is hard to realize the complex control system.
