摘　　要：本文仔细分析了高能强子-强子碰撞中,间歇程度对矩阶数、多重数和横功量的依赖性通过考虑α模型对多重数的依赖发现,只要在低能时间歇程度对多重数具有与高能情况相反的依赖性,那么,间歇程度对矩阶数在高能和低能时具有不同依赖性的实验现象便能得到很好的理解,这一事实可能表明:间歇程度更基本地依赖于横动量,本文的预言可以从对低能实验数据的分析中得到检验。The dependences of intermittency degree on moment-order, multiplicity and transverse momentum are discussed. It is pointed out that the difference between the dependences of the anomalous exponents of factorial momen s on moment order at energies lower and higher than top ISR energy implies that the dependences of intermittency degree on multiplicity are in opposite directions in the two energy tegimns. It is argued that these different trends imply that intermittency degree depends on other more basic quantity, such as transverse momentum. These assertions and their deductions remain to be examined experimentally.
