Abstract: The electronic states in the symmetric N - potential wells are studied. Based on the Schrdinger equation,the linear equations determined by the standard conditions in the case of N = 1,2,3 and 4 are solved,the energy level and wave function are accurately calculated by using Mathematica. The mechanism of the energy level splitting into energy band is exhibited.
