稳态法测不良导体导热系数实验装置的改进

传统的稳态法测量不良导体的导热系数是用红外线灯泡当作热源，用热辐射的方式对被测样品进行加热，新改进的加热方式是用电熨斗当热源，采用接触的方式进行加热。实践证明：新改进的加热方式具有实验操作简单，测量的结果误差小，节省电能，降低成本等特点。

The Improvement of the Experimental Device of Measuring the Thermal Conductivity of Poor Conductor by Using the Steady State Method

The traditional steady state method uses infrared bulb as heat producer to measure the thermal conductivity of poor conductor and thermal radiation to heat the measured sample, while the improved heating way uses electric iron as heat source and adopts the way of contact to heat up. The practice shows that the improved way of heating posesses the qualities of easier operation, smaller error of the measuring result, saving electric energy and reducing cost.
