摘　　要：A self-affine analysis of multiparticle production in pp collisions at 400 GeV/c was performed by using the method of continuously varying scale and the method of the factorial moments of continuous order.The self-affine generalized fractal dimensions and multifractal spectrum have been obtained.The self-affine multifractal spectrum is concave downward with a maximum at q=0,f(α(0))=D(0)=1.D(q)decreases with increasing q showing that there is self-affine multifractal behaviour in multiparticle production at the 400GeV/c pp collisions.The Levy indexμ>1 indicates that a non-thermal phase transition may exist in the pp collisions at 400 GeV/c.
