摘　　要：The erraticity in the random-cascading α model is investigated. It is found that, contrary to previous expectations, even in the pure single-α random-cascading model without putting in any particle, erraticity behaviour exists and the corresponding entropy indices do not vanish. This means that the dynamical fluctuations in a pure single-α model have already occurred event-by-event. The models with multiple-α strengthen this fluctuation. Taking the double-α model as example, the variation of the event-space fluctuation strength with the mixing ratio of the two αs is studied in some detail. The influence of the particle number on the results when the particles are put into the system is also investigated.
