忽略三体和四体相互作用的粗粒度版本的Asakura-Oosawa模型的相关性进行检查。的第一个几维里系数的二元非添加剂硬球混合物的代表这个模型和那些所产生的粗粒度（成对）耗尽势近似之间的映射允许定量评估这种相互作用的效果。这对于大的尺寸比和大的储层聚合物填充分数是特别重要的。
The relevance of neglecting three- and four-body interactions in the coarse-grained version of the Asakura-Oosawa model is examined. A mapping between the first few virial coefficients of the binary nonadditive hard-sphere mixture representative of this model and those arising from the coarse-grained (pairwise) depletion potential approximation allows for a quantitative evaluation of the effect of such interactions. This turns out to be especially important for large size ratios and large reservoir polymer packing fractions.
