主　　题：resistance superconductivity transition 

摘      要：The recent report of superconductivity in nitrogen-doped lutetium hydride(Lu-H-N)at 294 K and 1 GPa brought hope for long-sought-after ambient-condition ***,the failure of scientists worldwide to independently reproduce these results has cast intense skepticism on this exciting *** this work,using a reliable experimental protocol,we synthesized Lu-H-N while minimizing extrinsic influences and reproduced the sudden change in resistance near room *** quantitative comparison of the temperaturedependent resistance between Lu-H-N and the pure lutetium before reaction,we were able to clarify that the drastic resistance change is most likely caused by a metal-to-poor-conductor transition rather than by ***,we also briefly discuss other issues recently raised in relation to the Lu-H-N system.
