分别取２秒与２０秒为单元对１０例失神发作３Ｈｚ棘慢波放电作ＣＳＡ研究，结果发现每阵放电均于３Ｈｚ附近峰最高，在此峰之外的较高频段伴或不伴１～３个次高峰，与综合波的棘波有关；名峰频均从放电开始到结束逐渐减慢。表明ＣＳＡ可对此型放电进行识别和深入认识，值得进一步研究。此外，本文还就单元长短对放电检出的影响进行了讨论，认为适时检测中以取较短单元为宜 Taking 2 seconds and 20 seconds as the unit, respectively, 10 CSH studies of 10 Hz spike-and-slow wave discharges of absent-onset seizures were performed. The results showed that the highest peak near 3 Hz was observed in each array of discharges, with or without 1 to 3 Each peak, and the spike wave of the integrated wave; peak peak frequency gradually slow down from the beginning to the end of the discharge. This indicates that CSA can recognize and deepen this type of discharge and is worth further study. In addition, this article also discussed the impact of cell length on the discharge detection, that timely detection to take shorter units is appropriate
