The Research and Application of Digital Image Measurment Technique for Surface Flow Field and River-regime in Physical Model;

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.

Based on the approximation of the surface distribution of the ground current due to the skin effects and of the equivalence between the surface magnetic field and surface current density, this paper designs a novel magnetic field measurement apparatus which is applied to the test of th.

For S polarization,the angular distribution of fast electrons can be explained by taking account of the surface magnetic field qualitatively.
