Abstract: In this paper the influence of the differently distributed phase-randomozed to the data obtained in dynamic analysis for critical value is studied. The calculation results validate that the sifficient phase-randomized of the different distributed random numbers are less influential on the critical value. This offers the theoretical foundation of the feasibility and practicality of the phase-randomized method.
