A systematic analysis of the icosahedral hierarchic structure in the 3D icosahedral quasicrystal and its approximants have been made. There is an icosahedron at the center surrounded by 12 icosahedra. If two neighboring icosahedra are vertex-sharing, the multi-shell Mackay cluster consisting of 127 atoms will form. If two neighboring icosahedra penetrate into each other, the multi-shell Samson-Bergman-Pauling cluster consisting of 137 atoms will form.

The research results are highly reproducible owing to the repeatable micro-model technique.(2) Quantifying the Kr-S-P curves in two-phase flow. The validity and adaptability of multi-phase curves are verified using micro-model testing bed tailored to adequate scale of pores. Results obtained from the P-S micro-model tests generally agree with the threshold values of displacement mechanism offered by researchers using geometric shapes. The hysteresis of .experimental Kr-S curves of numerous two-phase flows are depicted in terms of connectivity and humidification. The P-S and Kr-S curves of two-phase flow are well-derived in conjunction with micro-model test results and empirical van Genuchten model. For the curve expressing the relation between saturation and capillary pressure, experimental results of water-air flow system corresponds to the theoretical data.
