Abstract ： We generalize a model, which was presented by Norman [Phys. Rev. Lett. 79 (1997) 3506], to calculate the Bi2 Sr2 CaCu2 O8+δ (Bi2212) single-electron tunnelling conductance. In our calculation result, the dip feature appears which has been widely observed in tunnelling experiments. It is found that this dip feature in tunnelling experiment and the dip/hump feature in angle-resolved photoemission experiment have a common physics. Moreover, it is shown from our numerical calculation method that if the spectral function A(K,ω) is known, the tunnelling conductance can be obtained.
