A 2D PIC model was used to simulate the PIII process for a planar target. The simulation results in one whole pulse show that the sheath expands with a decreasing speed and the sheath shape would change form elliptically cylindrical to circularly cylindrical. The dose distribution of ion implantation in the target surface is not uniform, and the concentration depth profiles of retained dose are considerably different, in different positions of the target.

The experimental result shows that when the discharge time was more than 1.5μs, small crack emerged in the fuses due to mechanical force on the heated fuse, and the metallized layer would be evaporated as the crack became long enough to generate disruptive discharge. When the discharge time was less than 150ns, small crack emerged in the fuses due to the current heat, and the metallized layer would be evaporated as the crack became long enough to generate disruptive discharge.

Results indicate that the observed salt fluxes under the two wind conditions show a marginal difference. Under the steady wind condition, a DBL with a constant thickness of 3.5 cm is observed right above the deposited sediment. The molecular diffusion is found to be the dominant mechanism for salt transport within the DBL. The latter can suppress the hydrodynamic enhancement on the exchange of substances between deposited sediments and overlying water.
