Periodical attenuation of Al(OH)3 particles from seed precipitation inseeded sodium aluminate solution WU Yu-sheng(吴玉胜)1, ZHANG Di(张 迪)1, LI Ming-chun(李明春)1, BI Shi-wen(毕诗文)2, YANG Yi-hong... the decrease of the specific surface area of seeds, which is the major reason causing explosive attenuation of Al(OH)3 particles in seed precipitation process. Key words: Bayer process; sodium......
Synthesis and Characterization of Y-Doped Mesoporous CeO2 Using A Chemical Precipitation Method Xu Dayu1,Qiu Guanzhou1,Li Yukun1,Jiang Nan1,Song Xiaolan1 (1.Department of Inorganic Materials... using a chemical precipitation method, under an alkalescent condition. Properties of the obtained samples were characterized and analyzed with X-ray diffraction (XRD), energy dispersive analysis of X-rays......
as the research object, a universal open-circuit fault location method which can be applied to multiple control strategies is proposed in the paper. If the switch open-circuit fault happens in inverter..., to diagnose and locate the open-circuit fault in a half cycle. Moreover, this method requires neither system control signals nor sensor. The validity, reliability and limitation of the fault location method......
