Furthermore, a new tensor splitting algorithm is proposed by incorporating Anderson acceleration techniques.展开更多
A new kind of Anderson type chromium molybdates containing the rare earth elements are synthesized, which have the general molecular formula of (NH4)6[CrMo5Ln(OH2)2O24H6]·xH2O (Ln=La,Ce,Pr,Nd,Sm,Gd and Yb).

The components of theseheteropoly complexes are determined by chemical elemental analysis, ICP and TG DTA. And IR, UV, ESR,XPS and 1H NMR are also applied to characterize the complexes as well. The results indicate that the structures of these complexes are Anderson B type and the rare earth elements are in the inner sphere of the heteropoly salts. The thermal stabilities of these complexes studied by TG DTA show that the range of pyrolysis temperature is between 490℃and 500℃.展开更多
