在电镀中,衡量镀层均匀性的分散能力是一个重要的概念。在电镀书藉中,对分散能力的论述不多。本文根据已经成熟的电磁场理论,作些解释。阴极电流初次分布是影响分散能力的决定性因素,弄清楚电流初次分布对分散能力的理解有极大的帮助。有如图1所示的阴极 In electroplating, the ability to measure the uniformity of a coating is an important concept. In electroplating books, the discussion on the ability to disperse small. This article according to the mature electromagnetic field theory, make some explanations. The initial distribution of cathodic current is the decisive factor affecting the dispersion ability. It is helpful to understand the primary distribution of current to understand the dispersion ability. There is a cathode as shown in Figure 1
