一个标度形式的配分函数的对数适用于零温度临界点，并发现持有的球形模型在小于两个维度和经典的n分量海森堡线性链。然而，几种情况下，发现涉及比热的临界指数关系失败。这些异常情况并不意味着重整化群理论基本公式中隐含的标度分解。（auth）
A scaling form for the logarithm of the partition function suitable for a zero-temperature critical point is obtained and found to hold for the spherical model in less than two dimensions and the classical n-component Heisenberg linear chain. Nevertheless, several cases are found where the critical-exponent relations involving the specific heat fail. These anomalous cases do not imply a breakdown of the scaling implicit in the basic formulation of renormalization-group theory. (auth)
