It was established that, the fish skin was stirred two times with 2.5% or 5% NaCl solution at a ratio of material to solvent of 1:10 at about 5℃ for 12h, about 5.9%, 6.7%, 9.1% soluble non-collagenous protein could been separated from skin of silver carp, bighead carp and grass carp, then by homogenizing with acid at a ratio of material to solvent of 1:30, about 78.9%, 84.1%, 82.0% of collagen from skin of silver carp, grass carp and bighead carp could be extracted by acetic acid or citric acid.

结果表明，鲢、鱅鱼皮经2.5％NaCl溶液(1：10)，草鱼鱼皮经5％NaCl溶液(1：10)，温度5℃左右，12h磁力搅拌处理二次，除去的可溶性蛋白分别占原总蛋白的5.9％、6.7％、9.1％。鱼皮再经加酸(1：30)溶胀、均质处理后，即可得到鱼皮胶原蛋白的粗提取液，鲢、草鱼鱼皮的酸提取回收率以醋酸为最高，分别为78.9％、84.1％，鱅鱼皮以柠檬酸为最高，约为82.0％。

First use soap-free emulsion preparation for polystyrene spheres, and the kernel, Reuse are silicon acetic tetraethyl ortho-silicate in ammonia catalytic hydrolysis, formed under the condition of silica, charged by six water or their cerium, six of methylene amine solution HMT (4) into the negatively charged, uniform cerium oxide coated surfaces to PS microspheres, core-shell structure of PS - CeO2 and PS - SiO2 composite microspheres.

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。
