The equation of advection and diffusion for the related problem was analyzed in thispaper. The conditions for the definite solution to the equation were given. The analytic solution ofpoisonous gas concentration distribution was worked out. The reasonableness of this solution wasdiscussed. The result is also of significance for other similar problems.展开更多
