## 摘要

The variation of hole states with Pr doping for Y _{x} Pr _{1-x} Ba _{2} Cu _{3} O _{7} and Y _{x} Pr _{1-x} Ba _{2} Cu _{4} O _{8} has been investigated by O K-edge X-ray absorption spectroscopy. Upon Pr substitution, T _{c} suppression rate in Y _{x} Pr _{1-x} Ba _{2} Cu _{4} O _{8} is slower than that in Y _{x} Pr _{1-x} Ba _{2} Cu _{3} O _{7} . For both systems, hole carriers in the CuO _{2} planes and CuO chains decrease monotonically with increasing Pr doping level. The depletion rate of hole carriers in the CuO _{2} planes with Pr doping in Y _{x} Pr _{1-x} Ba _{2} Cu _{4} O _{8} is considerably slower than that in Y _{x} Pr _{1-x} Ba _{2} Cu _{3} O _{7} . The oxygen content affects the depletion rate of hole carriers in cuprates with Pr doping.
