摘要翻译：
从理论上研究了带电胶体（宏观离子）在相反电荷的平面基底上的吸附。适当地考虑到宏观离子的有限尺寸，报道了不寻常的行为。研究发现，在宏观离子吸附过程中，碳离子（与底物带相同电荷符号的小盐离子）的作用对理解宏观离子吸附过程的机理至关重要。特别是，这些碳离子会聚集在衬底表面附近，并导致反直觉的{表面电荷放大}。

英文摘要：
The adsorption of charged colloids (macroions) onto an oppositely charged planar substrate is investigated theoretically. Taking properly into account the finite size of the macroions, unusual behaviors are reported. It is found that the role of the coions (the little salt-ions carrying the same sign of charge as that of the substrate) is crucial to understand the mechanisms involved in the process of macroion adsorption. In particular, the coions can accumulate near the substrate's surface and lead to a counter-intuitive {\it surface charge amplification}.
