Coordinates and moments of equivalent sources of various kinds of slow activity--local, generalized and synchronous (delta- or theta-ranges) -- were estimated on a computer on the basis of a model of single equivalent dipole, by the method of the coordinates descent. Investigation of local delta-activity caused by a volume process in the brain shows that its localization coincides with the peripheral zone of the tumour. Localization of the delta-focus enables to indicate its position not only on the surface, but in the depth of the brain as well. The dipole localization method helps to specify the concept of "secondary" slow waves and to differentiate slow activity of total brain-, brain-stem and local nature.
基于单个等效偶极子模型，通过坐标下降法，在计算机上估计了各种慢活动（局部、全身性和同步性，δ或θ频段）等效源的坐标和矩。对大脑中体积过程引起的局部δ活动的研究表明，其定位与肿瘤的周边区域一致。δ波灶的定位不仅能够在大脑表面，还能在大脑深部指示其位置。偶极子定位方法有助于明确“继发性”慢波的概念，并区分全脑性、脑干性和局部性的慢活动。
