随着分形概念及理论的广泛应用和向分子生物学的渗透，人们从单个蛋白质的研究上升到对蛋白质网络的研究。

Along with the widespread of fractal concept and theory and its application in molecular biology, the research has been richened from the single protein to the protein network.

为此，研究了利用分形理论对农作物病变叶片自然纹理图像进行了处理，利用BP网络来实现自然纹理图像的分类问题。

So, the problems, that utilize the theory of analyzing figure to dispose crop pathological changes laminate nature texture image, and utilize BP network to class nature texture image, are studied.
