Large temperature and concentration differences taking place in CVD process lead to natural convection and concentrationdiffusion which interact with forced convection and complex reactor geometries.
The defining aspect of Yemen is the diffusion of power rather than the concentration of it.
对也门的形势起着决定性作用的,与其说是权力的集中,倒不如说是权力的分散。

This modeling system has the same conditions as Gaussian diffusion model, and can calculate any concentration isoline's rigor time space location and specific points location.
