This paper studies the Static Electricity Field and corresponding equipotential lines,and power lines upon condition that Charged Conductor of Cylinder near by the earth.

0, we have obtained the exact solution of electrical potential functions and power line functions; Plotted the relative equipotential line maps and power line maps,which are orthogonal each other.

0 , we have obtained the exact solution of the electrical potential functions and power line functions; plotted the relative equipotential line maps and power line maps; meanwhile, we have made the necessary discussion.

A specific bursting, parabolic bursting induced by veratridine, has been observed in rat injured sciatic nerve.

Application of power lines to modern communication systems;

Power Line Communication in New Epoch;

Implementation of radio induction communication in power line;

Study and realization of wireless phase measurement for high voltage electric power line;

Aiming at the damage of thunder,it points out the necessity of discussing the lightning protection and grounding of distribution system,and makes discussion from the lightning protection and grounding of electric power line and electrical equipment and electronic equipment,to find the method of avoiding the lightning stroke and assure the line and equipment avoid the lightning stroke.

Analysed the reasons of high wastage for the electric equipments like asynchronous dynamo, electric power line, electric transformer and lighting system in normal industrial enterprise and put forward a series of alteration measures.
