【 摘 要 】

Thermal conductivity is one of important indexes of material's quality evaluation. This material's thermal conductivity detection system was designed and made based on the least square support vector machine algorithm. The system hardware was made mainly by microcontroller ATmega64, the temperature detection circuit and heating and refrigeration circuit. The system software was based on virtual instrument development platform of Labwindows/CVI and the least square support vector machine algorithm, which has data collection and processing, and the results display and control functions. Application shows that this system has advantages of reliable operation, precise temperature control and high thermal conductivity detection accuracy.
