The paper offers the method of drawing the electric fluxline in ordinarycircumstances and discusses the application of the method through examples.

This paper-goes into details of measuring electrostatic field by analogy and points cot that the density of electric fluxline at any point is directly proportional to field intensity of this point.

On the basis of defination about electric line of force,properties of some special electric line are discussed.

The present article analyses the two different graphes of electric line of force for a pair of the same charge given in many general physics textbooks both at home and abroad.

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.
