Abstract: Based on the principle of superposition，the distribution of electric field intensity on the central axis

of the three-dimensional point charge system with fullerene C60 lattice structure is calculated. Two kinds of electric

field intensity distribution are given respectively: the x-axis ( i.e.，the central axis) is selected from the Pentagon

center at the bottom to the Pentagon center at the top and the x-axis is selected from the hexagon center at the bottom

to the hexagon center at the top. It is found that the electric field intensity at the center ( the original point) is

zero. The electric field intensity on the central axis varies with the axial direction，but the distances between the

maximum value of the electric field intensity in the axial direction and the center ( the original point) are the same.

Key words: 3D-point charge system, fullerenes structure ( C60 ) , axial electric field
