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。

While the sample was dissolved in nitric acid and hydrofluoric acid, the silicon in sample was removed through evaporating in the form of silicon fluoride. As a result, the matrix interference was eliminated, and meanwhile the high blank value as well as the influence on the life span of graphite tubes due to perchloric acid was avoided.

使用硝酸和氢氟酸消解样品，使硅生成氟化硅蒸发掉，消除了基体的干扰，也避免了使用高氯酸作为消解试剂所引起空白值高及对石墨管寿命的影响。

Commonly used white and other light-colored Shoushan stone, soak in nitrite iron [Fe (NO3) 2] solution, and then out to dry; also be directly used yellow, orange and light red Shoushan Stone carving, and placed in the shell fire or electric rice chaff box, temperature 3000C ±, about 12 ~ 30 hours, you can get red ocher ~ thick ocher.

通常使用白色及其他浅色寿山石雕，浸泡于亚硝酸铁[Fe(NO3)2]溶液中，然后取出使其干燥；也可直接用黄、橙和浅红色寿山石雕，置于稻糠壳炉火或电热箱中，恒温3000C±，约12~30小时，即可获得红赭~浓赭色。

The La0.6Sr0.4Co0.2Fe0.8O3-δ composite oxide was prepared via combined EDTA-citrate complexing process with concentrated nitric acid treatment. The treatment would result in the self-combustion of solid state precursors at low temperatures.

在EDTA-柠檬酸联合络合法制备LSCF复合氧化物的过程中，利用浓硝酸对LSCF的固态前驱体进行处理，实现前驱体低温自燃烧反应。
