对于相互作用势具有硬核和负值部分的流体，如果第一个转变已经存在，则硬核的软化可以产生第二个转变。我们给出了晶格气体中第二次跃迁发生的一般论证，以及具有两个一阶跃迁的一维流体模型的明确结果。一个这样的模型还提供了一个打破直线直径定律的例子。
For a fluid in which the interaction potential has a hard core plus a negative part, softening of the hard core can produce a second transition if a first already exists. We give a general argument for the occurrence of the second transition in the lattice gas, plus explicit results for one-dimensional fluid models with two first-order transitions. One such model also provides an example of the breakdown of the law of rectilinear diameters.
