摘 要：We present an analytical solution to reconcile the vibration frequency shifts of graphene under the stimuli of the uniaxial-strain and pressure from the perspectives of bond order-length-strength(BOLS)correlation and the response of the BOLS to the applied *** duplication of measurements clarified that:(i)the pressure-stiffening of phonons results from bond compression and work hardening;(ii)
