Abstract ： We analyse further the entanglement purification protocol proposed by Feng et al. [Phys. Lett. A 271(2000)44] in the case of imperfect local operations and measurements. It is found that this protocol allows of higher error threshold. Compared with the standard entanglement purification proposed by Bennett et al. [Phys. Rev. Lett. 76(1996)722], it turns out that this protocol is remarkably robust against the influences of imperfect local operations and measurements.
