With the effective-mass approximation and the method of diagonalized the Hamiltonian, the eigenvalue of energy and the eigen-wave-function of GaAs quantum dots in the polarized 10 electrons has been calculated in the parabolic potential energy , and the clear electronic structures has been gained by the methods one-body and two-body density functions. The electronic structures and the magic angular momentums in the quantum dots are analyzed with the symmetry constraints .
