Analysis of Rock Thermal Model
岩石的热模型分析

The rock heat-transfer model which involves the rock infrared spectral behavior and thermal properties (thermal inertia) has been derived based on the analysis of several rock thermal models. Much lab or field data were used to compute the disrnal temperature variation on the rock surface. From the diurnal temperature variation curves of rocks with different thermal inertia, it can be shown that the diurnal temperature variation of the rock with high thermal inertia value is much larger than that of the rock with low thermal inertia value. When the albedo, emmissivity and vertical heat flux of the rock were changed respectively, only the magnitude of the rock diurnal temperature changed and the whole trend of temperature variation did not change greatly. This was very different from the case that the rock thermal inertia changed.
