%X Under the effective mass approximation,some empirical formulas are obtained numerically concerning the correlations between the quantum well widths of finite potential barrier structure and those of infinite potential barrier structure under the circumstance that the ground state energies of two different models are equal in electric field,which match well with the results given by others.Then the wave functions and binding energies of excitons are analyzed,verifying the rationality to replace the effective width in electric field with that in zero field.
