Abstract: A few of polynomial identity structures defined on complex field have been discussed and studied. The removing of correlation between polynomial coefficients and their zero center of gravity can be obtained from the distribution identity structure. The number of zero can be changed with the center of gravity identity structure. The dynamic displacements of polynomial zeros can be realized by spreading identity structure on the skeleton of balance. So that, the studies on the zeros of polynomial can be looked upon as the studies on the constructions of polynomial identity structure, its properties and the way to pick them up.
