摘　　要：The destruction of a regular black hole event horizon might provide us the possibility to access regions inside black hole event horizon.This paper investigates the possibility of overcharging a charged Taub-NUT regular black hole via the scattering of a charged field and the absorption of a charged particle.For the charged scalar field scattering,both the near-extremal and extremal charged Taub-NUT regular black holes cannot be overcharged.For the test charged particle absorption,the result shows that the event horizon of the extremal charged Taub-NUT regular black hole still exists while the event horizon of the near-extremal one can be destroyed.However,if the charge and energy cross the event horizon in a continuous path,the near-extremal charged Taub-NUT regular black hole might not be overcharged.
