The analysis results show that with the increase of the deposition temperature, the H content decreases, and the densification of the film increases.When the temperature is up to 360℃, the stoichiometrical rate of Si:N is close to 0.75. The protective property of Si3N4 films is also examined.展开更多

In automated equipment for orientation research, the intensity for drawing up the pole figure is measured in detail. The present research shows that the accurate pole figure can be drawn up without measuring concretely the intensity. For directional Si steel sheet the measuring step may be 4~5 degrees. In this paper the experimental equation for defo-cusing correction was derived from the experimental data in different specimens with random orientation.展开更多
