Theoretical derivation indicates that time averaged three-order cumulant of signals, which are from(random) phase harmonic processes, is nonzero and its one-dimension slice is also a harmonic process.

理论推导表明，随机相位谐波过程时间平均三阶累积量为非零值，而且其一维切片仍然是谐波过程。

A process which is coupled to the narrow band of brain temperature could allow all normal human brains to be affected by a sub-harmonic whose frequency range at about 10 Hz would only vary by 0.1 Hz.

与大脑温度的狭窄范围相对应的一种过程可能使得正凡人脑遭到一种频次范围在大约10赫兹并且只在0.1赫兹范围内变化的次谐波的影响。
