摘　　要：本文根据Hadamard变换谱系数(had谱系数)与布尔列矢量的关系以及Haar变换谱系数(ha谱系数)与布尔列矢量的关系,提出了had谱系数与ha谱系数之间的图形转换方法,并举例说明转换过程。该方法揭示了had系数图与ha系数图之间的内在联系,具有简单、直观的特点。According to the relation of Hadamard transform spectral coefficients and Boolean column, and the relation of Haar transform spectral coefficients and Boolean column vector, a transform method between these two kinds of spectral coefficients is proposed, and the transform process is illustrated by examples. The essential relationship between had coefficients map and ha coefficients map is revealed. This method has such features as simplicity and intuition.
