The experimental results indicates that the optimum pH range was 1.60~2.20, and the optimum H2O2 concentration was 10.0 mmol/L. The degradation ratio increased with the increasing concentration of ammonium ferric oxalate in the range from 0.1 to 1.0 mmol/L, but no significant increase in degradation ratio was observed when the concentration was above 1.0 mmol/L. When the concentration of fuchsin basic increased, the degradation ratio dropped, while the concentration of degraded fuchsin basic rised. When the concentration of fuchsin basic was low, the degradation followed first-order kinetics, but when it was high, the degradation could be fitted by zero-order kinetics. The absorbtion of fuchsin basic at 543 nm disappeared quickly, while the absorbtion of intermediates formed during the course of fuchsin basic dagradation at 298 nm vanished slowly.

The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.

Firstly, the incommensurate magnetic scattering of the doped single-layer triangular lattice in the normal state has been studied. It is shown that away from half-filling the commensurate peak is replaced by six incommensurate peaks located at [ (1-δ〓), ] , [ (1-δ′〓), ] , [ (1-δ"〓), ] , respectively, and 〓〓. The incommensurability parameter δ increases with doping at lower doping concentration, while saturates at higher dopings. These peaks broaden and weaken in amplitude with increasing energy and temperature, with the positions of the incommensurate peaks not changing with the energy.
