A location axis A and transmission lines, and a certain axis parallel to that coordinates of the points that the original point on the line between the current, two-line voltage is variable and coordinates the function variable, respectively, to time E R , said.

Takes position coordinate axis A and the transmission reel parallel, and takes some for this coordinates zero point, on-line electric current, two space voltage all is the coordinates variable and the time variable function, respectively by E, R indicated.

Get location parallel to the axis a and transmission spool, and take a point to the origin of the coordinate, electric current, the voltage between the two lines on the line is a function of coordinates and time variables, respectively, e, r, said.
