gradient direction meaning in English

渐变方向

Then based on the gradient projection method , the gradient projection direction is deduced . the gradient direction is the base for sensitivity analysis
接着，根据投影梯度法，推导出了投影梯度方向，该梯度方向是灵敏度分析的基础。
The method of bispectrum reconstruction detects fracture zones by learning the difference of frequency components because fracture can change the frequency components of seismic responses . the theory of time - frequency analysis computes the difference in the gradient direction of time - frequency spectrum
双谱重构的方法就是根据裂缝会改变地震波频率成分的基本想法，通过求取具有不同频率成分的地震波的差异来实现对裂缝发育带的检测的。
