Abstract：
The variation of the quadrupole deformations β of the ground state even-even nuclei with A≥100 are investigated systematically. The studied nuclei are classified into different groups not only by their mass numbers but also by if the valence nucleons are particles or holes. Smooth behaviors of the β values against (N_pN_n)^1/2 are found with different slopes and trends in different groups of nuclei. This is explained as that the contribution to the quadrupole deformation from valence particles and that from valence holes are different. The behavior of the β values against (N_pN_n)^1/2 are also investigated for the nuclei near the drip lines. This seems to imply that the universal correlations under the N_pN_n scheme is still valid for nuclei far from stability.
