In order to investigate the protect effect of Mg sacrificial anode on the pipeline with interference of DC stray current along the length direction, we simulated field condition that Mg sacrificial anode was equipped at 4-meter intervals when Q235 pipeline (40 meters long) buried into soil with resistivity...

Based on the principle of chemical power source primary battery, the material selections of the positive and negative electrodes of the metal modified battery were studied. The selection methods of the positive and negative electrodes materials and the modification and correction of the copper thin and...

As a kind of negative dielectric constant material, finite plasma has some effect on antenna radiation. Results show the plasma layer with negative permittivity is inductive, which can compensate the capacitivity of the vacuum and enhance the radiation with proper para-meters. Furthermore, the shape...

The as-cast structure of C19400 copper alloy (Cu-2.32%Fe-0.035%P-0.11Zn in mass%) under electromagnetic field had been researched in this paper. It is shown that applying electromagnetic field during the solidification of C19400 copper alloy can promote columnar-to-equiaxed transition, refine grain,...
