Abstract：
A concept of copulative degree is Proposed in this Paper.Using the method of particle-group correlation's unction,the effects of the Particles with different correlative degrees on collective sideway now are studied for 1.2A GeV Ar+BaI₂ collisions at the Bevalac stream chamber.Our studies indicate that correlative degree is an important parameter on describing collective sideward flow Properties. The minority of correlative Particles(or fragmentS) with larger correlative degrees can produce the effect arising from the collective sideward now, but the effect arising from high-order collective flow correlations can not be dominated by these minority of Particles (or ragments).It is results from the collective contribution of the majority of collective particles(or fragments) with various correlative degrees.
