Query: Systematic study of nuclear charge radii along $Z=98$-$120$ isotopic
  chains   In this work, the evolution of nuclear charge radii along even $Z=98-120$
isotopes are systematically investigated by various approaches. The new
parametrization sets based on liquid drop model (LDM) formulas are proposed by
covering the shell closure effect at $N=126$ and odd-even staggering (OES) in
calibration procedure. In comparison with available database, high-order
neutron-proton asymmetry may be indispensable in fitting protocol. The fitted
formula within theoretical uncertainty below 0.02 fm is used to make
extrapolative calculations. Results obtained by the deduced relationship
associating to $\alpha$-decay properties and the modified charge radius formula
in relativistic mean field (RMF) model are also employed to make reinforce. The
latter shows that the abrupt change of nuclear charge radii emerges apparently
across $N=184$ shell closure. In addition, the abrupt jumps at $N=146$ and
$200$ are also disclosed remarkably due to the large deformation. These
different methods give comparable predictions of nuclear charge radii for
$^{286,288}$Fl, $^{290,292}$Lv and $^{288-310}120$ isotopes.
