英文摘要	Influence of the deformable substrate potential on Shapiro steps is investigated in the overdamped Frenkel-Kontorova model with incommensurate structure. Both the number and size of Shapiro steps are strongly affected by the deformation of substrate potential. As substrate potential gets deformed, the oscillation of Shapiro steps reduces and the periodicity of oscillation significantly changes. For some value of shape parameter r, the odd and even maxima oscillation forms of harmonic steps still maintain the Bessel-like form. Compared with those in standard potential, the amplitude dependence of harmonic step exhibits obvious difference. The dynamical DC threshold force correspondingly increases with rising the value of r.
