摘要 蛋白质和酶表面的粗糙性和不规则性具有分形特征.它们可用分形维数和质量指数来表征。用变分法计算的表面分形维数不同于用其它方法求出的值,因为变分法是适用于自仿射体系的,故本文所报导的结果对表面是可靠的.另一方面,对蛋白质和酶的胖分形和多重分形特征用模拟进行了研究。表面质量指数可视为另一种标度指数,谱f(α)提供了蛋白质和酶表面的更进一步信息.谱f(α)在酶反应体系中的应用也进行了讨论。 The roughness and irregularity of the surfaces for the protein and enzyme are of fractal features, they may be characterized by fractal dimensions and mass exponents. The surface fractal dimensions calculated by variation method are different from those obtained by other methods, since the former is applicable to the self-affine system, thus the results reported in this paper are reliable for the surfaces. On the other hand, the fat fractal and multifractal features of proteins and enzymes are studied by simulation. The surfce mass exponents are regarded to be another kinds of scaling exponents, and the spectrum f(α) Provides further detailed information about the surfaces of enzyme and protein. The applications of spectrum f(α) to the enzymatic reactions have been also discussed.
