当<math>2\beta+\gamma=2</math>，则有<math>\alpha =0</math>，这通常意味着对数发散而不是幂律发散，并且在<math>t=0+</math>和<math>t=0-</math>之间存在叠加有限不连续。在二维伊辛模型中，仅有对数关系而这种不连续是不存在的；而在平均场近似中情形相反。

What were probably the historically earliest versions of critical-point exponent relations like ({{EquationNote|8}}) and ({{EquationNote|9}}) are due to Rice [10] and to Scott [11].  It was before Domb and Sykes [12] and Fisher [13] had noted that the exponent <math>\gamma</math> was in reality greater than its mean-field value <math>\gamma =1</math> but when it was already clear from Guggenheim's corresponding-states analysis [14] that <math>\beta</math> had a value much closer to 1/3 than to its mean-field value of 1/2. Then, under the assumption <math>\gamma
