摘　要:該實驗實現對保溫材料導熱系數自動化的測量。把熱電偶傳感器采集到的信號經過處理，由采集卡將處理后的信號采集到計算機內，應用Labview軟件對該信號進行數據處理，從而測算出保溫材料的導熱系數，并以此方法測定幾種保溫材料的導熱系數。[著者文摘]

Thermal Conductivity Automatic Measurement of Insulated MaterialsZHAO Fa-gang,WANG Yun-xia Centre of Physics Experiment,Shanxi University,Taiyuan 030006,ChinaAbstract:In this experiment,the automatic measurement of thermal conductivity of insulated materials is achieved. The acquisition card acquire the signal from thermocouple sensor that has been processed,and then use the labview to process the signal and calculate the thermal conductivity of insulated materials. At the same time,we measure thermal conductivity of several insulated materials with this way.[著者文摘]
