The net enthalpy changes for the water desorption of sun-cured tobacco have been studied. In order to compare the values of net enthalpy changes for the samples at the same moisture contents, correlation analysis have been performed. As temperature and water vapor pressure increased, equilibrium moisture content approached the saturated vapor pressure of water. The values of 1nP against the reciprocal of absolute temperature were linear for the water desorption of samples. Multiple regression was analyzed to calculate the values of 1nP at the same moisture content. The significance of x2 test for the multiple regression was 0.5%
