摘要： 自Haralick提出计算机纹理分析的统计模型以来,纹理分析技术在遥感图象的识别与分类及细胞显微图象等医用照片的自动诊断上都获得了很好的效果,近年来,它的研究发展很快,并不断地开拓着新的应用领域,本文将这一手段引入表面催化的研究中,以催化剂表面的SEM图象为对象,利用计算机模式识别理论和方法,对催化剂的宏观或亚宏观形貌进行纹理解析,抽取各种表面纹理特征,并将这些特征值与催化剂表面的理化参数相关联,研究了催化剂表面的形成、变迁及其规律。

Abstract: The computer image texture analysis technique was used to investigate scanning electron micrographs (SEM) of catalysts. Various surface texture features were carried out. Relationships between these features and other physical and chemical properties of catalyst were studied. The form, change and regularity of catalysts' surface were analysed. This technique would be of avail for the computer-aided design and study of catalysts.

Key words: Catalyst, Surface image, Texture analysis
