铜虫 (小有名气)

[交流] 文章中这句话怎么理解???

原文:Preparation of Mo2C/GCSs: 0.10 g (NH4)6Mo7O24·4H2O and 0.20 g sodium alginate were grounded to form homogeneous powder. The solid mixture was annealing at 200 °C for 2 h, and then heated at 10 °C min-1 up to 900 °C for 6 h in Ar atmosphere. After cooled to room temperature naturally, the resulting black solid resulting was
collected, washed by centrifugation with distilled water several times to remove the residue of reactants, and finally dried in vacuum at 80 °C. The resulting power was sonicated at 480 W for 10 min to obtain Mo2C/GCSs (最后一句话的理解?).
最后一句的意思是:上述80 °C干燥得到的粉末,用480W的超声仪器超声处理10min?干粉直接超声吗?不需要水分散再去超声啊?
