Derivative of Chitosan oligosaccharide C60 was synthesized in heterogeneous phase alkalescent system.
在非均相碱性体系中,合成了C60 -低聚壳聚糖衍生物。

The auditory perception effect of the reconstructed speech is mainly dependent on the amplitude of the derivative of the additive phase with respect to frequency.
重建语音的听觉感知效果主要取决于附加相位对频率的导数的起伏幅度。

Secondly, relationship between the intensity and the partial derivative of the phase was derivate.
