项目摘要

Materials composed of earth an terrestrial planets and related experimental products have a variety of textures, from microscopic in atomic scales to macroscopic, depending on their conditions during formation and their histories. The purpose of the present study was to understand the formation and functions of the textures systematically by different approaches of describing, experimental and theoretical methods beyond the boundaries of individual scientific fields. Two research meetings or one meeting and one workshop were held in each academic year. In the "technical workshop on imaging, experiments and simulation (1) and (2)", establishment of basic method on quantitative description of the textures, especially on imaging technique, and experiments and simulations of texture formation were performed and discussed. In the research meetings, formation and functions of the textures were actively discussed by researchers both on earth and planetary materials and pattern formation physics. Differences between sciences on the textures of earth and planetary materials and metals were also discussed. As a result, it was concluded that the pattern formation physics in complex systems, especially in composite systems, is the most important clue to the formation of the textures, and that the development of a method which combines microscopic and macroscopic properties (e.g., combination of molecular simulation and homogenization method) is important to elucidate the functions of the textures.

由地球和类地行星及相关实验产品组成的材料具有多种纹理，从原子尺度的微观到宏观，这取决于它们形成时的条件和历史。本研究的目的是超越各个科学领域的界限，通过不同的描述方法、实验和理论方法系统地了解纹理的形成和功能。每学年召开两次研究会议或一次会议和一次研讨会。在“成像、实验与模拟技术研讨会(1)和(2)”中，对纹理定量描述的基本方法的建立，特别是成像技术的建立，以及纹理形成的实验和模拟进行了讨论。在研究会议上，地球和行星材料以及图案形成物理学的研究人员积极讨论了纹理的形成和功能。还讨论了地球和行星材料和金属的结构科学之间的差异。因此，得出的结论是，复杂系统，特别是复合系统中的图案形成物理是纹理形成的最重要线索，并且开发一种结合微观和宏观性质的方法（例如，组合分子模拟和均质化方法）对于阐明纹理的功能非常重要。
