摘　　要：通过观察发现,闭孔泡沫陶瓷气孔几何结构不是一个整形结构,而是具有分形特征的分形结构。采用分形几何对其气孔结构进行描述,首次获得了闭孔泡沫陶瓷分维表达式D=lnN/lnK。讨论了分维D的大小与闭孔泡沫陶瓷气孔微结构之间关系,并用计算机模拟出闭孔泡沫陶瓷的分形结构。In order to describe the cell microstructure of closed-cell ceramic foam,the fractal geometry was used and the formula of the closed-cell ceramic foam fractal dimension D=lnN/lnK was obtained firstly and simulation was performed with the computer.The results show that the cell microstructure of the closed-cell ceramic foam with computer simulation accords with the true microstructure of the sample.The relationship between the size of the fractal D and the cell microstructure of the closed-cell ceramic foam is discussed also.
