The smaller the electronegativity is, the higher oxidation activity is. Thus phosphomolybdic acid shows better catalytic oxidation activity than phosphotungstic acid.

由于磷钨酸中的钨可以脱出并少量沉积到催化剂表面，而且从电负性来说Mo-O的键能小于W-O，键能小的杂多酸有较强的氧化性，所以钼系杂多酸催化活性要好于钨系杂多酸。

RESULTS AND CONCLUSLON: A total of 2 of 6 autogenous bone grafting cases suffered from graft bone dislocation, 1 suffered from pseudoarthrosis formation, and 1 suffered from donated ilium. Six of 21 autogenous bone graft with cervical plate-screw fixation suffered from loss of intervertebral height, and 3 suffered from pain of donated ilium.
