求翻译：The water-based Fe3O4 ferrofluid dispersion was cooled to 70 8C, and 1 N HCl was added slowly to adjust the pH to 2 to ensure that oleate was converted to OA. The liquid was decanted; the black residue was washed several times with DDI water until the pH of the washing water was 7.The precipitate was then dried in an o是什么意思？ 待解决

水基的Fe3O4 ferrofluid分散作用冷却了对70个8C，并且1个N HCl慢慢地增加调整酸碱度到2保证油酸盐被转换了成OA。液体被倾析了;黑残滓被洗涤了几次用DDI水，直到洗涤液的酸碱度是7.The沉淀物然后被烘干了在60℃的一个烤箱。干OA上漆的Fe3O4微粒在一定数量的St被分散了由在室温的缓慢的搅拌。

水基 Fe3O4 磁流体扩散被冷却到 70 8 和 1 N 盐酸加入慢慢调整 ph 值为 2，以确保该油酸被转换了成 OA。倒出液体 ；黑色残留几次用水洗 DDI 直到冲洗水的 ph 值 7.沉淀然后烘干，60 ℃ 的烤箱中。干的 OA 涂四氧化三铁粒子被驱散在一定量的 St 缓慢搅拌室温。在这种方式，获得基于石油的 Fe3O4 磁流体 （四氧化三铁 — — St）。
