针对最常见的一类具有持续振荡特征的自发脑电（ＥＥＧ）信号情况，提出首先对其准周期特征参数统计测定，然后进行 １０次左右的错相刺激触发和叠加，使 ＥＥＧ信号的效应大部分互相对消，同时视觉诱发脑电（ＶＥＰ）信号明显增强，为后续系列文章中对叠加所得波形的处理打下较好基础．还给出了制定错相刺激触发策略所需的具体判据和应用示例．
Aiming at the most common type of spontaneous EEG signals with sustained oscillation, we propose to first measure the quasi-periodic characteristic parameters and then trigger and superimpose the wrong phase stimulation around 10 times so that the effect of EEG signals is large Part of the mutual cancellation, and visual evoked EEG (VEP) signal was significantly enhanced for the follow-up series of articles to lay a good foundation for the waveform processing. It also gives the specific criteria and application examples needed to make the wrong-phase stimulus strategy.
