摘 要：<正>Nd1-xSrxMnO3（x = 0.3,0.5） ceramics containing a secondary phase are synthesized by high-energy ball milling and post heat-treatment method.The 4-wire and 2-wire measuring modes are used to investigate the transport character of the grain/phase boundary（inner interface） and electrode-bulk interface（outer interface）, respectively,and the results indicate that there is a similar nonlinear l—V behaviour for both of the inner and outer interfaces,however,the electric pulse induced resistance change（EPIR） effect can only be observed at the outer interface.
