| 摘 要： | 为探究夏日冰洞地温异常的形成机制，结合热电学、矿物学、地球物理学等相关知识，提出一种基于热电效应的地温异常成因说。此假说认为：某些难以解释的地温异常现象可能是由地下电流经过导电矿物界面时产生的帕尔帖效应引起的，而地下电流可能来自某种自然电场，也可能来自地下温差所产生的塞贝克电势。在研究各类夏日冰洞乃至其他某些地温异常现象的成因时，建立了若干简单电路模型来推测地下可能形成的电路，并结合热电效应进行分析，对目前已有的地温异常现象做出成因推测。 |

| Abstract： | To investigate the formation mechanism of the geothermal anomaly of ice caves in summer, a hypothesis that attributes the geothermal anomaly to the thermoelectric effect from the relevant knowledge of thermoelectricity, mineralogy and geophysics was proposed in this paper. It was suggested that some unexplained abnormal geothermal phenomena may be caused by the Peltier effect when the earth current flows along the interfaces between two conductive minerals. The earth current arises from either a certain natural electric field or the Seebeck potential originating from the underground temperature gradient. When studying how various types of ice caves in summer and other geothermal abnormity form, the paper formulated several simple circuit models to conjecture the possible underground circuits, and thus successfully explained the presently known abnormal geothermal phenomena by thermoelectric effects. |
