通过分析近年发表的相关傅氏算法的文献，提出对几个问题的质疑，结合实际的工程实例和信号的物理意义，认为信号的虚部是-b即相量用In=an-jbn表示，才能正确计算出阻抗、负序分量等。

After the phase inversion point,the dynamic rheological parameters increase greatly with adding water.

实验结果表明，体系在相反转点前表现为牛顿流体行为，粘度几乎不变﹔相反转点时，体系粘度增加幅度很小，体系的有关动态流变参数(剪切储能模量、损耗模量和复数粘度)均出现极小值，将此归于局部连续水相的润滑作用﹔进一步加水，体系的动态流变量增加，意味著相反转在相反转点后仍在继续进行。
