An intraparticle diffusion was the rate-controlling step for the adsorption of phenol on activated bamboo charcoal. 颗粒内扩散模型分析表明，活性竹炭对苯酚溶液的吸附过程中，颗粒内扩散为主要速率控制步骤。
It is doubtful that the diffusion or ideal mixing stage models can satisfactorily represent the behavior of gas in fluidized beds. 扩散模型或者理想混合级模型能否满意地表示气体在流化床中的性状是可以怀疑的。
