The result shows that nonlinearity of the system induces the fractional harmonic which roots in the noise.
说明系统运动非线性产生的分数次谐波，是诱发噪声的直接原因。

The method is to find out a fractional factor that makes the fractional differenced result closest to the white noise.
该方法实质是寻找一分数阶因子，使随机分形信号通过分数差分后的输出信号最接近白噪声。

It is shown theoretically that the fractional lower order array output power is bounded when the fractional lower order is less than half of the characteristic exponent of the noise.
