摘要(中)

熱探針法是以等向性材料做為考量設計的，不能直接測量異向性材料，本研究嘗試將熱探針法推廣至量測橫向等向性材料。
參考前人的實驗配置，將橫向等向性岩石依照片理方向進行裁切，利用熱探針法進行熱傳導係數的量測，並使用非定常細線加熱法與暫態平面熱源法量測以驗證熱探針法量測橫向等向性岩石熱傳導係數之可行性。
實驗結果顯示，在熱探針適用性方面，以電壓12Volt跟熱傳導係數為3W/mK的導熱泥即足以提供實驗所需。在數據處理方面，使用改良加權移動平均可以有效的降低誤差及計算偏差的發生。於暫態平面熱源法、熱線法及熱探針法的量測結果大致相符，可看出以熱探針法量測橫向等向性岩石的熱傳導係數是可行的。

摘要(英)

This paper presents the characteristics of thermal conductivity in transversely isotropic rocks by using thermal probe method, transient plane source method, and transient hot-wire method, respectively. Schists (8 samples) were tested in this paper. In thermal probe method tests, this paper used moving average algorithm to tackle the excessive noise in measuring thermal conductivity. To investigate the relation between thermal conductivity and P-wave velocity, this paper also addressed the ultrasonic measurement instrument to obtain different orientated P-wave velocities in transversely isotropic rocks, hence, the thermal conductivities can be verified with the data of P-wave velocity. The results show that the thermal conductivities obtained from thermal probe method, transient plane source method, and transient hot-wire method are fairly agree well with each others. This paper proposed the above mentioned three methods can be used in measuring thermal conductivity in transversely isotropic rocks.
