摘　　要：不同介观带电粒子(聚离子)的电双层之间的等效相互作用是目前软物质研究的前沿。本文主要评述胶体系统在这一领域的研究现状,包括标准Poisson-Boltzmann或平均场理论对于电双层研究的局限性和微离子之间空间相关性的重要性;尤其是相关性引起的聚离子之间等效相互作用为吸引的可能性,等效聚离子电荷(电荷重正化)和电荷规范化的计算方法,约束对于胶体粒子之间等效相互作用的影响和电双层溶剂粒度的统计描述,指出仍存在的问题和研究前景。Much of the present studies focus on the effective interaction between electric double layers associated with different mesoscopic charged particles(polyions). The present review mainly comments the outlook of colloidal system in this field, including the limitations of the standard Poisson-Boltzmann or mean-field theory of electric double layers and the importance of spatial correlations between microions; especially the possibility of an attractive component of the effective interaction between polyions, the effective polyion charge (or charge renormalization) and charge regulation, the effect of confinement on the effective interaction between colloids and the solvent granularity of statistical description of double layers. The problems to be further researched and the prospect of the field are pointed out.
