具有广泛性的层状结构的普适模型研究进展

Preliminary Study on the Universal Model of Layered Structure With Universality

从地理、生物、环境、材料、化学和物理等不同领域列举了普遍存在的自然界和人工制备的层状物质,说明了层状结构物质存在的广泛性,且发现高科技前沿领域中(如石墨烯、有机太阳能电池、航空复合材料和仿生材料等),为获得多功能于一体,越来越多新材料采用层状结构;同时也发现,层状结构虽种类繁多,但都客观存在层间界面上特定参数(如位移、声压和应力等)连续和各层依次递推影响的特点,故对于任何领域的任意多层层状结构,能否构建一个能体现该特点的普适的数学模型以研究其内在关联和综合整体性能,是个值得研究的重要基础性难题,本研究对此进行了初探,创建了该普适模型的基本构架。

This paper enumerated ubiquitous natural layered materials and artificially layered materials from different fields, such as geography, biology, environment, materials, chemistry and physics, illustrating the extensive existence of layered structures. It has been found that in the high-tech frontier areas, more and more new materials adopt layered structure(such as grapheme, organic solar cells, aviation composites and biomimetic materials)in order to achieve multi-function integration;at the same time, it has been also found that although there are a variety of layered structures, they all objectively have the characteristics of continuity of specific parameters(such as displacement, sound pressure and stress, etc.) on the interlayer interface and recursive influence of each layer in turn. Therefore, for any multi-layered structure in any field, it is an important and fundamental problem to build a universal mathematical model that can reflect these features so as to study its internal correlation and comprehensive overall performance. In this paper, a preliminary discussion has been made on this and the basic framework of the universal model has been established.
