摘要: 本文对哈林槽的几何尺寸与分散能力数值的关系进行了分析探讨,结果表明,在应用Haring-Blum公式和Luke公式时,分散能力数值不仅与远近阴极与阳极间距离之比(K)有关,而且与哈林槽的绝对长度(近阴极至阳极的距离Ln)有关;在应用Heatley-Pan公式和Fjeld公式时,分散能力的数值只与Ln有关,而与K值无关。在吡呵酸镀银和氰化物镀银液中的实验证实了上述分析。

Abstract：The relationship between the numerical vaiues of the throwing power (T.P.) and the absolute geometric dimensions of Haring Cell was studied by theoretical analysis and experimental examination.Assuming that the current efficiency is equal to 100% on the two cathods, the relationship between the numerical values of T. P. and geometric dimensions of Haring Cell can be expressed in the following manner.T.P.=(For Haring-Blum's definition)T.P.=(For Heatley-Pan'sT.P.=(For Field's definition)T.P.=(For Luke's definition)These expressions show that the numerical values of T.P.depend on the ratio L_n/Lf and the distance of the nearer (or further) cathod to the common anode in the case of Haring-Blum's definition or Luke's definition and only depend on L_n in the case of Heatley-Pan's or Field's definitions.These conclusions were confirmed by experimental results o btained in the case of electroplating of silver from picolinic acid and cyanide systems.
