The pressure respones of Configuration entropy and information dimension of atomic energy distribution in amorphous iron is aralysed We calculate the particle number distribution of atomic energy, and take the information entropy of it as the configuration entropy of the amorphous structure. The calculated results suggest that the atomic energy distribution curve and the configuration entropy are relate to the energy interual in statistics, e. g., there is a fractal scaling ruler between configuration entropy and the interval. The configuration entropy is determined by the average value of it in no scaling distribution range of atomic energy between lower bound and upper bound. The results of simulation indicate that information dimension is another efficient parameter to describe the degree of disorder in amorphous system, and the effects of pressure on fractal dimension and the degree of structural disorder in amouphous structure show complicated behavior.
