In the light of the height and streamline space distributions,a visulization scheme called surface streamline mapping is developed to mirror atmospheric movement features on isobaric surfaces objectively with more marked physical meaning compared to routine streamline field drawing method and higher values in a meteorological context.

Based on the elliptic shape characteristic of metallurgical junction boundary formed by lateral diffusion and vertical diffusion,the surface electric field distribution with a single floating field limiting structure is discussed.

Furthermore,the surface electric field in this structure reaches nearly ideal uniform distribution due to the additive ele.

The self-heating effect is alleviated as a result of the silicon window and the surface electric field are optimized by different substrate electric field modulation.

In the designing of transmission lines,the conductor surface field strength is one of the restriction factors,in order to balance the charge and surface field of different phases,to increase the utilization ratio of conductors,and to reduce the investment,this paper introduces a new scheme that uses different conductors in border and middle phases.
