摘要翻译：
颗粒间势具有硬核，在中等分离度时具有吸引力，在较大分离度时具有排斥性的流体表现出新的相行为，包括稳定的不均匀相。在这里，我们报告了一个联合模拟和理论研究这样一种流体，重点是液-汽转变线与任何新相的关系。在一定的长程斥力振幅下，研究了相图与吸引振幅的关系。我们发现斥力的作用是用两个一级跃迁取代液汽临界点和部分相变线。其中一个转变是将蒸气从球状液体团簇的流体中分离出来；另一个将液体从球形空隙的流体中分离出来。在低温下，两条过渡线相交，在三相点处为汽液过渡线。虽然大多数积分方程理论无法描述新的相变，但Percus Yevick近似确实成功地捕捉到了汽-团簇转变以及团簇流体结构的各个方面，与模拟结果合理一致。

英文摘要：
  Fluids in which the interparticle potential has a hard core, is attractive at moderate separations, and repulsive at greater separations are known to exhibit novel phase behavior, including stable inhomogeneous phases. Here we report a joint simulation and theoretical study of such a fluid, focusing on the relationship between the liquid-vapor transition line and any new phases. The phase diagram is studied as a function of the amplitude of the attraction for a certain fixed amplitude of the long ranged repulsion. We find that the effect of the repulsion is to substitute the liquid-vapor critical point and a portion of the associated liquid-vapor transition line, by two first order transitions. One of these transitions separates the vapor from a fluid of spherical liquidlike clusters; the other separates the liquid from a fluid of spherical voids. At low temperature, the two transition lines intersect one another and a vapor-liquid transition line at a triple point. While most integral equation theories are unable to describe the new phase transitions, the Percus Yevick approximation does succeed in capturing the vapor-cluster transition, as well as aspects of the structure of the cluster fluid, in reasonable agreement with the simulation results.
