Influence of Concentration Distribution on Cross Diffusion Level in Building Room

The relationship of contaminant gas concentration distribution influence on cross diffusion character and level among temperature, humidity was obtained according to the non-equilibrium thermodynamic theory. under different were discussed, combining real temperature in building room. results show that grads vapor mass are less than zero when additional coefficient both positive or negative, otherwise two more zero. And higher initial levels, greater absolute values grads, with same coefficient. While is finite, remarkable.
