摘      要：Synchronization has great impacts in various fields such as self-clocking,communication,and neural ***,we present a mechanism of synchronization for two mechanical modes in two coupled optomechanical resonators with a parity-time(PT)-symmetric *** is shown that the degree of synchronization between the two far-off-resonant mechanical modes can be increased by decreasing the coupling strength between the two optomechanical resonators due to the large amplification of optomechanical interaction near the exceptional ***,when we consider the stochastic noises in the optomechanical resonators by working near the exceptional point,we find that more noises can enhance the degree of synchronization of the system under a particular parameter *** results open up a new dimension of research for PT-symmetric systems and synchronization.
