水分渗入 meaning in English

ingress of water
moisture penetration
penetration of moisture

The experimental study is designed to observe the flow process by use of morphological method in different kind of soils . macropore geometry is subsequently characterized by using fractal dimensions of staining patterns on horizontal cross - sections . the results prove that water flow in structured clay soils is strongly influenced by the presence of macro - pores and their geometries
为了更深入地了解物质在多孔介质中的运移，本论文进行了土柱模拟实验，将含颜料的水分渗入不同类型的土壤中，然后对其不同深度的剖面进行观察，并且进行了图像分析，发现颜料的分布满足分形特征，水分在土壤中的运移存在优势流现象，受到大孔隙的影响很大，这与上述随机模拟的结果是一致的。
