Based on vector-spectrum method, the concept of vector amplitude-frequency figure and vector waterfall figure is established.

基于全矢谱理论，定义全矢幅频特性图和三维全矢瀑布图的概念。

When frequency is up to the base frequency, the amplitude of voltage vector is restricted constant.

但当频率上升到基频后，定子电压受到变频器最大输出电压的限制而不能进一步提高。

Then the every frequency amplitude of auditory correlogram was coded as a feature vector expressing present frequency band characteristic.

并将听觉相关图中每个频带的频率分量幅值进行特征编码作为表征当前频带特性的特征向量。
