The thermal diffusivity of lunar regolith was estimated to be about 1.0 x 10(exp -8) sq m/s from the attenuation factor of annual temperature variations propagating into the lunar regolith (Langseth et al., 1976). In this work, the main focus is to re-evaluate the thermal properties of lunar regolith from short term events such as the diurnal temperature variations and the lunar eclipse. In order to analyze these temperature variations preliminarily, a simple model computation was utilized with uniform thermal properties. If we assume thermal diffusivity of 1.0 x 10(exp -8) sq m/s, the amplitude of temperature variations in lunar eclipse and diurnal variations is almost consistent with those recorded by the Apollo 15 temperature sensors. However, this model can explain neither the delay of heat transfer with depth nor the outline of the temperature profile compared to that of the recorded ones. In order to be consistent with each other, the thermal diffusivity is preferable to be 1.0 x 10(exp -6) sq m/s which is two orders lager than that was estimated by previous studies.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063505014","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学 大学院理学系研究科"},{"subitem_text_value":"東京大学 大学院理学系研究科"},{"subitem_text_value":"Open University Planetary and Space Sciences Res.
