Molecular Dynamics Simulation on Diffusivity of Pure CO_2 System 纯CO2体系扩散性质的分子动力学模拟
Determination of Molecular Sieve Diffusivity by Gas Chromatography 气相色谱法测定分子筛扩散系数
Effective Knudsen diffusivity, viscous flow parameters and effective molecular diffusivity of gases in a reforming catalyst were measured with a single pellet diffusion reactor based on the "dusty gas" model. 根据多孔介质的尘埃气模型,用单片扩散反应器测定(?)气体在重整催化剂中的有效努森扩散系数、粘性流动参数及有效分子扩散系数。
The results indicate that magnetic field have positive effect on the molecular mass-transfer process of water, methanol, ethanol, formic acid and acetic acid in the air, viz diffusivity increase in the magnetic field. 研究结果表明,磁场对水、甲醇、乙醇、甲酸及乙酸在空气中的分子传质过程具有正效应,即在磁场中的扩散系数增大。
