Abstract：
The generalized liquid drop model (GLDM) and the cluster model have been employed to calculate the α-decay half-lives of superheavy nuclei (SHN) using the experimental α-decay Q values. The results of the cluster model are slightly poorer than those from the GLDM if experimental $Q$ values are used. The prediction powers of these two models with theoretical $Q$ values
from Audi et al. (Q_Audi) and Muntian et al. (Q_M) have been tested to find that the cluster model with Q_Audi and Q_M could provide reliable results for Z>112 but the GLDM with Q_Audi for Z≤112. The half-lives of some still unknown nuclei are predicted by these two models and these results may be useful for future experimental assignment and identification.
