Estimating calculation method of consistencycan be used to calculate bleach agent consistency in the saturation water of fiber cell wall.. The main cause of the reaction rate of displacement bleaching being faster than that of conventional bleaching is that the bleaching agent consistency in the saturation water of fiber cell wall, when bleach liquor mix with pulp by displacement way, is bigger than that of by conventional way.

浓度估算法可用于估算漂剂在纤维细胞壁饱和水分中的浓度，置换漂白比常规漂白反应速度快的主要原因在于漂液以置换方法与纸浆接触混合后纤维细胞壁饱和水分中漂剂的浓度比常规方法的高。
