在临界区，我们给出了简单立方晶格上伊辛模型比热的定量表达式。该表达式基于蒙特卡罗方法获得的数值结果的有限尺寸标度。它与级数展开式和一组实验结果令人满意地吻合。我们的结果包括确定了临界点两侧比热散度的普遍振幅比。
We provide an expression quantitatively describing the specific heat of the Ising model on the simple-cubic lattice in the critical region. This expression is based on finite-size scaling of numerical results obtained by means of a Monte Carlo method. It agrees satisfactorily with series expansions and with a set of experimental results. Our results include a determination of the universal amplitude ratio of the specific-heat divergences at both sides of the critical point.
