rate of mass transfer

用法例句

The relationship between flow length and mass transfer speed of volatile substances through a raicroporous flat hydrophobic Teflon film was investigated.

本文以电解氯化钾制取钾碱过程溶解在淡盐水中氯和氢氧化钠水溶液为体系,研究了挥发性物质通过微孔疏水性聚四氟乙烯平面膜的传质速度和流程长度间的关系。

The mass transfer velocity was presented based on the heat - mass transfer analogy, the Fick's first law wasdeveloped, and the mass transfer differential equation for the transient mass transfer was set up.

依据热量、质量传递的类比关系，提出了质量传播速度的概念，继而对传质本构方程－费克第一定律进行了修正，以此为基础，建立了瞬态分子扩散传质问题质量传递微分方程式，并以一维瞬态扩散传质问题为例对本文所述问题进行了理论上的分析。
