摘　要:该实验实现对保温材料导热系数自动化的测量。把热电偶传感器采集到的信号经过处理，由采集卡将处理后的信号采集到计算机内，应用Labview软件对该信号进行数据处理，从而测算出保温材料的导热系数，并以此方法测定几种保温材料的导热系数。[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]
