| Abstract: | In order to decrease the effect of automobile emission, more and more experts are studying the dispersion models for exhaust pollutants. This paper introduces several such models applied in the field of vehicle exhaust pollutants and in the same time, aims at perfecting these models based on the understanding of the absorbing function of green plants and their effect of dispersion- the diffusion function of plants-as well as the geographical environment, buildings, the direction and speed of wind and the time of shining. We hope that this can promote the dispersion models and further develop the control techniques. |
