An ultra-low loss and high conversion efficiency silicon waveguide is used as sampling gate via four waves mixing, and 5.2 effective number of bits of signal at 40-GHz is achieved by 2-GHz cavity-less pulse source.
Polychromatic sets theory is summarized. Based on the study of process demand for silicon piece manufacturing and process sequence, the polychromatic sets theory was applied to construct the mathematical model of silicon piece process planning. The model was comprised of contour matrix and polychromatic graph, which were respectively used to describe the process demand for silicon piece manufacturing...
A new process of directly smelting boron steel from boron-containing pig iron has been established. The starting material boron-containing pig iron was obtained from ludwigite ore, which is very abundant in the eastern area of Liaoning Province of China. The experiment was performed in a medium-frequency induction furnace, and Fe2O3 powder was used as the oxidizing agent. The effects of temperature,...
