摘　　要：建立了用Riesz基函数表达的多分辨分析模型，在模型中研究了空间正交性条件与完全重构条件的满足，得出了包含正交小波分析的更具普遍性的多分辨分析模型。The Risez base functions are the bases of multiresolution pyramid defined by Mallat. We use them to build the model of multiresolution analyais. We also study the space orthogonality condition and the perfect reconstrution condition. This model is a general multiresolution model which includes the orthogonal wavelet analyais as its special model.
