By coupling the radiation transport equations and rate equations of X-ray laser, gain saturation process of several X-ray lasers in Ne-like Ge plasma is studied and simulated results are compared with calculation of the usual saturation equation. The great differences have been found in deep saturation stage. Simulated results also show the "burn-hole" in gain curves and decrease and increase in line width with increasing target length before and after saturation.
