The pseudorapidity distributions of charged particles produced in relativistic heavy-ion collider experiment are analyzed by the thermalized two-cylinder model. The calculated results are compared and found to be in agreement with the experimental data of $\chem{Au}$- $\chem{Au}$ collisions at the maximum RHIC energy (the energy in the center-of-mass reference frame is $\sqrt{s}=200A$ $\un{GeV}$) which is the maximum energy in the present accelerator energy region.
