Abstract：
We study the ground state properties of even Dy isotopes, from the proton drip line to the neutron drip line, in the Relativistic Continuum Hartree-Bogoliubov theory with the NL-SH parameters. Firstly, our results show that theoretical binding energies and nuclear root mean square radii are in good agreement with the available experimental data. Secondly, we draw the following conclusions by investigating the calculated results: 1. within the neutron shell on N=82—126, there is an obvious sub-shell between the ranges of N=84—92 and N=94—126; 2. the predicted neutron drip line nucleus is $^{250}_{66}\rm Dy_{184}$; 3. characteristics of halos and giant halos appears in $_{\hspace{5.8ex}66}^{\text{240—250}}\rm Dy_{\text{174—184}}$ nuclei, among which there my be the giant halos.
