【摘要】 Brand等作者认为,以S=RT/nF为初值时,迭代法得不到未知浓度C₀的收敛解。本文理论分析证明,以不同初值（S=RT/nF或C₀）的迭代法的收敛性和发散性具有一定的客观规律性。进而又成功地计算了氯、钙和铬离子等实例。计算结果与现有资料中的电算结果完全相符。更多还原

【Abstract】 Brand et. al. consider that it is does not lead to convergence of anunknown concentration C₀ when the iteration method is to put S=RT/nF. Theoretical analysis of this paper shows that convergence anddivergence of the method with different initial values （S=RT/nF or C₀）have definite objective laws, and then it is successfully used tocalculate the concentrations of chloride calcium and lead cations. Theresults are completly consistent with those obtained by computer incurrent literature.更多还原
