As the foundation for developing general software simulating the diffusion - reaction processes involved over a pellet of catalyst, this model has obvious advantage over others used usually.

作为单颗粒催化剂上反应-扩散过程通用模拟软件开发的基础，该模型明显优于其他常规模型。

Except for considering the processes of transfer and diffusion of air pollution matter, the model covers the photochemical reaction effects as well.

模式除考虑污染物在大气中的输送、弥散过程外，还加入了光化学反应过程。

This insight allowed Dr Kealy and Dr Wollkind to create equations that, once plugged into computer simulations of reaction-diffusion processes, produce all manner of lifelike tiger-bush schemes, including the most intricate sort.
