摘要
在改进传统稳态测量方法的基础上，开发了一套基于LabVIEW图形化编程语言的虚拟测试系统，利用PC机强大的数据处理能力对采集的数据进行实时处理并直观地显示处理结果，极大地简化了测量设备和操作步骤。将此系统应用于某实验材料导热系数的测定，达到了比传统测量仪器更高的精度和更快的速度。
In this paper, a virtual measuring system based on LabVIEW is designed after improving the traditional steady-state method, the sampled data are real-time processed and the result is displayed visually by utilizing the powerful ability of data processing of the PC, then the measuring equipment and the operation process are predigested. When this system is applied to measuring the thermal conductivity of an experimental material, it gains higher precision and faster speed than the traditional measuring instruments.
