研究了淀粉-水混合物干燥过程中所观察到的定向裂纹扩展现象的图案动力学。为了使干燥断裂过程的三维结构可视化，进行了两种实验，即，树脂固化刨平法和用MR仪器实时测量含水率分布。在这两个实验中，具有多边形结构的横截面是可视化的。测量单元尺寸的深度依赖性。本文还讨论了水输运的唯象模型。
Pattern dynamics of directional crack propagation phenomena observed in drying process of starch-water mixture is investigated. To visualize the three-dimensional structure of the drying-fracture process two kinds of experiments are performed, i.e., resin solidification planing method and real-time measurement of water content distribution with MR instruments. A cross section with polygonal structure is visualized in both experiments. The depth dependency of cell size is measured. The phenomenological model for water transportation is also discussed.
