Study on the specific heat of wood by statistical mechanics

摘要

From the microstructure of wood, theoretical expressions of the wood specific heat were derived by statistical mechanics. With the theoretical expressions derived, the theoretical values of specific heat for 33 tree species. With different moisture contents and under varied temperature conditions were calculated and compari- son was also made to the experimental values under the same conditions. The results showed that the maximum error and mean error by the theoretical expressions of this paper are only 7.8/100 and 2.5/100 respectively, while those error of the theoretical values for 33 tree species calculated with Dunlap's empiric equation were 15.2/100 (max.) and 9.3/100 (mean), and for Kиpиллов empiric equation, they were 20/100 (max.) and 11/100 (mean).
