 note = {P, Apparent cooling constant of the earth's crust was difined by the author as follows. About the 10m depth's strata of the earth has constant temperature. Above it, the soil temperature changes by season and day. By calculating 10m depth's soil temperature gradient, the apparent cooling constant which contains the thermal effect of the upper 10m soil layer was difined. Its values was found about the same order to the crust thermal effluent values.},
