研究了二维周期晶格上随机场Ising模型的临界迟滞现象，该模型的配位数z（eff）在3≤z(eff)≤6的范围内变化。我们发现模型支持4<z(eff)≤6范围内的临界行为，但临界指数与z（eff）无关。本文结合非平衡临界现象的普遍性和该领域已有的结果对结果进行了讨论。
We study critical hysteresis in the random-field Ising model on a two-dimensional periodic lattice with a variable coordination number z(eff) in the range 3≤z(eff)≤6. We find that the model supports critical behavior in the range 4<z(eff)≤6, but the critical exponents are independent of z(eff). The result is discussed in the context of the universality of nonequilibrium critical phenomena and extant results in the field.
