Unlike the scaling laws ({{EquationNote|1=8}}), ({{EquationNote|1=9}}), ({{EquationNote|1=14}}), and ({{EquationNote|1=15}}), which make no explicit reference to the dimensionality, the <math>d</math>-dependent exponent relations ({{EquationNote|1=16}})-({{EquationNote|1=18}}) hold only for <math>d<4\ .</math>  At <math>d=4</math> the exponents assume the values they have in the mean-field theories but logarithmic factors are then appended to the simple power laws. Then for <math>d>4\ ,</math> the terms in the thermodynamic functions and correlation-function parameters that have as their exponents those given by the mean-field theories are the leading terms. The terms with the original <math>d</math>-dependent exponents, which for <math>d<4</math> were the leading terms, have been overtaken, and, while still present, are now sub-dominant.

标度律({{EquationNote|1=8}})，({{EquationNote|1=9}})，({{EquationNote|1=14}})和({{EquationNote|1=15}})没有明显的和空间维数相联系，而({{EquationNote|1=16}})-({{EquationNote|1=18}})则是依赖于<math>d</math>的指数关系式，且仅对<math>d<4\ </math>成立。对于<math>d=4</math>，热力学函数中依据平均场理论给出的以相关函数参数为指数的项是主要项。而本身在<math>d<4</math>时，包含依赖于<math>d</math>的指数的主要项，虽然依然存在，但是被取代而变成次要项。
