When the intensity of the driving pulse is much higher than the saturation intensity of the media involved, the double peak splitting in frequency domain emerges in the generated high order harmonic spectra. The possible origins of this splitting are carefully investigated. The ionization of the gas media and the propagation effect of harmonic field are the main reason for the double peak splitting observed.

A study has been carried out on the feasibility of using high iron content wastes, generated during steel making, as a raw material for the production of glass ceramic. The iron-rich wastes were mixed and melted in different proportions with soda-lime glass cullet and sand. The devitrification of the parent glasses produced from the different mixtures was investigated using differential thermal analysis, X-ray diffraction, and scanning electron microscopy. The mechanical properties of the glass-ceramic were assessed by hardness and indentation fracture toughness measurement. A glass ceramic with mixture of 60 wt pct iron-rich wastes, 25 wt pct sand, and 15 wt pct glass cullet exhibited the best combination of properties, namely, hardness 7.9 CPa and fracture toughness 3.75 MPa·m^1/2, for the sake of containing magnetite in marked dendritic morphology. These new hard glass ceramics are candidate materials for wear resistant tiles and paving for heavy industrial floors.

The magnetic properties, structure defects of electrodeposited Fe-Ni-P alloys with various compositions and the thermostability at amorphous state have been studied by DSC, positron annihilation and electronic integrating instrument methods. The results show that the thermostability of amorphous Fe-Ni-P alloys increases with Fe content. Emergence and recrystallization of stable phases defer as the P content of the coating increases. The minimum H-c, B-r and P-h occur at 9.4 P (wt pet) content. Maximum H-c, B-r and P-h occur at the weight ratio of Fe to Ni equaling to 1/9.

The surface enhanced Raman scattering (SERS) spectra of human gallstones is investigated. Complicated Raman bands were due to multiple components that include bilirubin, bilirubinate salts, cholesterol, fatty salts and proteins. The results suggest that besides bilirubin and cholesterol, fatty salts and proteins may play an important role in the formation of gallstone. The experimental data supply an useful information for the research of the formation mechanism of gallstones.
