水溶液氧化

The oxidations were performed in H2O2 aqueous solution at temperature not higher than 60℃.

氧化反应在H2O2水溶液中和不高于60℃的温度下进行。

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。

Generation I type capacitors having electrodes comprised of ruthenium oxide and an aqueous electrolyte were investigated extensively during the past 25 years but have never reached commercial scale production, primarily, because of cost issues.

第一代的电容器电极上负载了氧化钌，采用水溶液电解质，在过去的25年中开展了广泛的研究，但是从来没有商业化的密封产品出现，只要原因是因为价格因素。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
