摘　　要：强子统计的判据是广义Pauli定理;反常维度γ_(BF)(δ_p)是广义Pauli定理中的导数的连续阶数.在强子—核,核—核碰撞中的外强相互作用场内产生的质子枚举动量,用符合广义Pauli定理的理论分布做分析.这些带参数ν_B的分布已与大量实验数据符合.结果表明:新生质子与反冲质子的枚举动量数据与带参数ν_F的理论一致.有效理论指出:维度(正则维度,反常维度)是可测物理量.从理论与数据的比较,我们有:2γ_F(g_R)=-5/6(质子).The generalized Pauli theorem is the criterion of hadron statistics. The anomalous dimensions γBF(gR) are the continuous order of the derivatives in the generalized Pauli theorm. The inclusive momentum data of protons produced in the external strong interaction fields of hadron-nucleus and nucleus-nucleuss collisions are analysed by the theoretical distri butions which are consistent with the generalized Pauli theorem. These distribution expressions with VB is in agreemet with a lot of the experiment data. The new born protons and the recoil protons in the hadron-nucleus, nucleus-nucleus and proton-proton collisions, have the momentum distributions which are loincident with the theoretical ditributions with VF. The effective theory shows that the dimensiongrad(can-onical dimension, anomalous dimension) is a measureable physical quantity. By comparing theory and data, We have 2γrF(gR) =- 5 / 6 for the proton quantum fields.
