首先用无皂乳液制备了聚苯乙烯微球，并以此为内核；再利用正硅乙酸乙酯在氨水催化条件下水解，形成带负电性的二氧化硅，或者利用六水亚硝酸铈、六亚甲基四胺水溶液分解出带负电性的氧化铈，均匀的包覆到PS微球表面，形成核-壳结构的PS-CeO2和PS-SiO2复合微球。

A method for the analysis of zinc oxide phase content in sulfide ore was studied. On the basis of the characteristics of each phase component, the sulfide ore sample was leached twice with NaOH and acetic acid-ascorbic acid, respectively, so that the oxide mineral and zinc oxide were dissolved completely. The leaching rate of zinc oxide phase was up to 98 Vo. Moreover, the dissolution of zinc sulfide phase was effectively inhibited, solving the problems of selective leaching and determination for zinc oxide.

研究了硫化矿中氧化锌相含量的分析方法，根据硫化矿中各物相组分特点，提出了用氢氧化钠溶液和乙酸－抗坏血酸溶液二次浸取硫化矿，使锌氧化矿、氧化锌充分溶解，氧化锌相的浸取率达到98%以上，同时有效地抑制了硫化锌相的溶解，较好地解决了氧化锌相选择溶解测定的问题。
