For fluids of molecules with short-ranged hard-sphere-Yukawa (HSY) interactions, it is proven that the Noro-Frenkel "extended law of corresponding states" cannot be applied down to the vanishing attraction range, since the exact HSY second virial coefficient diverges in such a limit. It is also shown that, besides Baxter's original approach, a fully correct alternative definition of "adhesive hard spheres" can be obtained by taking the vanishing-range-limit (sticky limit) not of a Yukawa tail, as is commonly done, but of a slightly different potential with a logarithmic-Yukawa attraction.
对于短程硬球- Yukawa（HSY）相互作用分子的流体，已经证明，Noro-Frenkel“扩展对应状态定律”不能应用于吸引力范围消失的情况，因为精确的 HSY 第二维里系数在此极限下发散。还表明，除了 Baxter 的原始方法之外，通过取 Yukawa 尾部而不是通常情况下的粘性极限，即取具有对数 Yukawa 吸引力的略有不同的势能，可以获得“粘性硬球”的完全正确的替代定义。
