      다국어 초록 (Multilingual Abstract)

      Recently thermal properties of rocks have been highly concerned in geothermal energy development and in many field of engineering.
      An experimental apparatus based on the transient hot wire comparison method was built for measuring the thermal conductivity of both plate and curved surface.
      A new method was developed for deforming the time range necessary for calculation of the thermal conductivity in order to measure it accurately. The range is determined by using the second derivative of hot wire temperature with respect to logarithm of time.
      The thermal conductivity of samples was measured in an airconditioned room.
      The thermal conductivity of metal materials is able to be measured both in the plate and model in the curved surface model within ±17% accuracy and in case of none-metal material is able to measured with in ±7.5% accuracy.
      Therefore, we can be easily obtained a new measuring method of thermal conductivity of curved curved surface in coring material.
