diffusion controlled surface reaction model 扩散控制表面反应模型
The leaching process is controlled by mixed steps:the surface chemical reaction and the diffusion passing through the silicon and iron mineral phases.
浸出过程属于混合控制，即表面化学反应与通过不溶硅、铁矿物相的扩散为过程的控制步骤。
The calculation results show that the greater the flow velocity, the lower the supersaturation degree, and the easier the scale formation process will be controlled by a surface reaction.
计算结果表明流速越大，过饱和度越小，结垢过程越易为表面反应所控制；流速越小，过饱和度越大，结垢过程越易为对流传质所控制，且往往发生在液壁温差较大，壁温较高的情况下。
