根据同时平衡原理和电中性原理研究了Ｚｎ（Ⅱ）－ＮＨ＿３（ＮＨ＿４）＿２ＳＯ＿４－Ｈ＿２Ｏ系Ｚｎ（Ⅱ）－氨络合平衡问题，全面揭示了锌的溶解度规律，发现该体系存在有锌的高溶解度区域，这为氨法锌冶金展现了光辉前景。
The Zn (Ⅱ) -NH_3 (NH_4) _2SO_4-H_2O complex Zn (Ⅱ) -ammonium complex was studied based on simultaneous equilibrium principle and electroneutrality principle. The solubility law of Zn was revealed comprehensively. It was found that Zn High solubility zone, which shows brilliant prospects for ammonia zinc metallurgy.
