摘要:在稳态法的前提下，TC-3B导热系数仪采用开启风扇和不开启风扇两种方法，DR-II导热系数仪采用电压调为200V使加热盘温度达到80℃再把电压调为100V,电压调为100V，电压调为150V三种方法，对各种材料的导热系数进行测量，通过对测量结果以及达到稳态所用时间的比较分析得出在测量方面哪种方法好以及哪套仪器好的结论以及仪器需要改进的地方。

Abstract:With the premise of steady-state method, there are two kinds of methods to utilize the TC-3B thermal conductivity meter. They are the use of the meter with its ventilator open and the use of the meter without its ventilator open. The DR-II thermal conductivity meter works to heat the platen to 80℃ with the voltage of 200V, then switch the voltage to 100V, then to 100V, and then to 150V. The present study will measure the coefficient of heat conductivity of several different kinds of materials. Through the analysis and discussions of the data and founding, as well as the time period of becoming steady state from measuring, the author will make a conclusion about the better meter and the better measuring method. Some suggestions are also offered to improve the measurement with thermal conductivity meter in steady-state method.
