Under the proper concentration, flocculation efficiencies are ideal: the structures of bridging flocculated aggregates are compact, their settling velocities are great, the residual turbidity of the supernatant is low under the quiescent settling experiment and the fractal dimension value is high. 合适浓度下的高分子架桥絮体结构密实、沉速快,静沉实验中上清液余浊低,分维值高,絮凝效果好。
Measured by a sensor, dynamic error and quiescent error are unavoidable to lie in true value C ( t) and measured value Cm ( t) of parameter. 利用传感器进行测量时,被测参数的真实值C(t)与测量值Cm(t)之间,不可避免地存在静态和动态误差。
