摘      要：A coupled heat and formaldehyde migration model based on the non-equilibrium thermodynamic theory and molecule movement theory was *** effect of temperature on the transport coefficients was simulated,and the simulation results were validated with experimental data from the *** calculation shows that air exchange rate larger than 2 h-1 should be prevented,if the purpose is only for formaldehyde emissions *** effects of temperature on formaldehyde migration are obvious.
