具有细胞结构的材料在自然界中广泛存在，包括木材、软木、植物薄壁组织和骨小梁。天然多孔材料通常具有很高的机械效率：例如，木材的蜂窝状微观结构使其具有极高的抗弯曲和屈曲性能指数。在这里，我们回顾了各种各样的天然细胞材料的力学，并研究了它们在轻质天然三明治结构（例如鸢尾叶）和天然管状结构（例如植物茎或动物刺）中的作用。我们还描述了两个工程生物材料的细胞结构的例子，旨在取代或再生体内组织。(C)2004爱思唯尔有限公司保留所有权利。
Materials with a cellular structure are widespread in nature and include wood, cork, plant parenchyma and trabecular bone. Natural cellular materials are often mechanically efficient: the honeycomb-like microstructure of wood, for instance, gives it an exceptionally high performance index for resisting bending and buckling. Here we review the mechanics of a wide range of natural cellular materials and examine their role in lightweight natural sandwich structures (e.g. iris leaves) and natural tubular structures (e.g. plant stems or animal quills). We also describe two examples of engineered biomaterials with a cellular structure, designed to replace or regenerate tissue in the body. (C) 2004 Elsevier Ltd. All rights reserved.
