渗透性是生物膜所具有的特性,指由浓度差引起的水分净移动的能力,如土壤和多孔岩石,指其允许水通过的能力;对于空气扩散器而言,是指允许空气通过的能力。从广义说,除了水以外,在外部环境的影响下,如:地震、自然界(太阳、风、雪、闪电等)同样可以使材料有渗透性。渗透性同溶质引起的渗透压大小与溶质分子或离子的数目多少成正比。

...物理边界界定工作与生活的场所,时间边界界定工作与生活的时间,心理边界则界定了人们在工作和生活的领域里分别适用的行为和情绪模式。边界有两个特征,一是渗透性(permeability),是指一个领域内的元素客观上进入另一个领域的程度,比如工作时间占用了家庭生活的时间,便是工作边界渗透性的表现。
