According to the scaling idea of local slope,we investigate numerically and analytically anomalous dynamic scaling behaviour of(1 + 1)-dimensional growth equation for molecular-beam epitaxy.The growth model includes the linear molecular-beam epitaxy(LMBE) and the nonlinear Lai-Das Sarma-Villain(LDV) equations.The anomalous scaling exponents in both the LMBE and the LDV equations are obtained,respectively.Numerical results are consistent with the corresponding analytical predictions
