Sometimes low voltage restraint outbreaking with high wave, slow waves and spikes appeared in 17 cases while wide low voltage restraint occurred in 10 cases, but false normal EEG appeared in 1 case.
发作期脑电图17例表现为高波幅慢波夹杂棘波爆发-低电压抑制，10例表现为全脑各导呈广泛性低电压抑制，1例表现为假性正常脑电图改变。
The results manifest that the dielectric-loading can lower the operating voltage of the ring-plane slow-wave structure. Good accordance was obtained between results by this method and that of CST-MWS.
计算结果与CST - MWS的模拟结果吻合良好，说明所提出的计算等效相对介电常数的方法和计算色散方程的方法对环板慢波结构是切实可行的。
