Diffusion scatters light, essentially making the light source broader and therefore softer.
运用漫散射分散光线的实质还是使光源变广，从而达到柔化光线的目的。
The model consists of a single advection? Diffusion equation with a source term.
此模型由一个单一的具有源项的对流扩散方程组成。
It is found that the maximum concentration often occurs near source through intensive vertical diffusion, and the values of concentration decrease with the distance downwind rather rapidly.
发现由于垂直扩散较强，最大浓度常于近源处发生，且向下风方浓度衰减较快。
