中文摘要：

介绍了近年来化学领域中有关分形体的制备及分形现象的实验研究,重点介绍了结合小波分析方法的分形理论在催化领域的应用情况。催化剂多为构型复杂材料,利用传统分析方法难以对其进行细节描述和定量分析。引入结合小波分析方法的分形理论,能同时利用分形标度不变性和小波多尺度分析这两方面的特点,定量描述催化剂复杂的表面形态和活性点分布等规律,有助于准确把握催化剂的结构,正确理解有关催化的现象与效应。最后对未来该领域的研究方向提出展望。

英文摘要：

The experimental study of the preparation of fractals and investigation of the phenomena of fractals and their application on chemistry,especially the application of fractal theory containing wavelet in catalysis were introduced.Most catalysts have complex structures.It is hard to describe in details and analytic quantitatively using traditional method,but fractal theory containing wavelet could do it.The combination of fractal scalar invariability and wavelet multi-scales analysis may be used to characterize the surface morphology of the catalysis and the distribution of active points quantitatively.Therefore,it is helpful to set up the structure of the catalysis appropriately,and understand the mechanism and efficiency of catalytic reactions.Finally,the prospect of fractal containing wavelet in catalysis is outlined.
