摘　　要：强子质量与横动量间的非线性关联依赖于质量反常维度γｍ（ｇＲ），βｍ（ｇＲ）＝３［１＋γｍ（ｇＲ）／２］／２π（α※Ｓ＝０．１２８［ＱＣＤ］）与普适量〈Ｍ〉（０．１９２ＧｅＶ／ｃ２）．能量极小（动量极大）定理与强相互作用饱和性造成几个强子发射源的形成．关联链〈ｐ⊥（Ｍｉ）〉Ｍｉ／〈Ｍ〉，〈ＮＫＭＫ（ＮπＭπ）〉Ｎπ／〈Ｎπ〉，〈Ｎ（ｐ⊥）〉ｐ⊥／〈ｐ⊥〉反映的是非线性效应．The nonlinear correlations between hadronic mass and transverse momentum are connected with theanomalous massdimension γm(gR) and an universal quatity 〈M〉 (0.192GeV/c2),βm(gR)=3[1+γm(gR)/2]/2π,α*S=0.128(QCD) at fixed point.theorem of energy minimum (momentum maximum) and the saturation of strong interaction cause the formation of a few hadron emission souvce.The correlation chain,〈p⊥(Mi)〉Mi/〈M〉,〈NKMK(NπMπ)〉Nπ/〈Nπ〉,〈N(p⊥)〉p⊥/〈p⊥〉,relects the nonlinear effects.The massmass correlations reflect that the mass creation processes are all nonlinear in Multihadron Production.
