A process which is coupled to the narrow band of brain temperature could allow all normal human brains to be affected by a subharmonic whose frequency range at about 10 Hz would only vary by 0. 1 Hz.
加在大脑温度窄带上的一个处理能够允许所有正常的人类大脑被谐波范围在大约10赫兹正负0.1赫兹的次谐波所影响。
Although the naked eye can not see the light of the troubles within the frequency range can be achieved stealth, but the other band can still detect electromagnetic waves.
肉眼见不到的隐身衣虽然在光波频率范围内能够实现隐形，但是用其他频段的电磁波还是可以探测到。
Band-pass filter (BPF) role is to allow a certain period of signals within the frequency range, while blocking signals outside this band.
带通滤波器(BPF)的作用是答应某一段频带范围内的信号通过，而将此频带以外的信号阻断。
