摘要翻译：
弱多分散体系的相行为，如粒径较小的胶体，可以微扰地与单分散体系的相行为联系起来。我展示了如何将这种方法推广到临界点附近保持良好的行为，避免了现有方法的分歧，并提供了多分散相平衡的一些关键定性特征。分析还解释了为什么在纯尺寸的多分散系统中，临界点异常地位于云和阴影曲线的最大值附近。

英文摘要：
  The phase behaviour of a weakly polydisperse system, such as a colloid with a small spread of particle sizes, can be related perturbatively to that of its monodisperse counterpart. I show how this approach can be generalized to remain well-behaved near critical points, avoiding the divergences of existing methods and giving access to some of the key qualitative features of polydisperse phase equilibria. The analysis explains also why in purely size polydisperse systems the critical point is, unusually, located very near the maximum of the cloud and shadow curves.
