| 摘 要： | 在分形理论的基础上，对多普勒声谱图进行了分数维分析，首次提出了以多普勒信号的分数维为Ｚ轴调制的声谱图，并应用于提取多普勒信号中的最大频移（最大速度），对这种新方法的优缺点也进行了探讨。

| Abstract: | The fractal anylysis of Doppler sonogram based on fractal theory was made,and the sonogram modulated in Z axis by the fractal of Doppler signals was developed the first time,which was applied to extract the maximum Doppler frequency shift(corresponding the maximum of velocity). The advantages and disadvantages of this new method was also reported in the paper. |
