Then we discuss the graphs which the GLR equation contains. We find that GLR had summed up some unreasonable cut graphs but lost some necessary cut graphs because of the application of the AGK cutting rule. Further more, GLR ignored the interference diagrams and their equation does not satisfy the momentum conservation.
