电解质中胶体体的泊松-玻尔兹曼模型是最近的一个数值计算的基础，预测了两个被限制在圆柱体中的胶体球之间的吸引力。本研究提出了一个分析证明，该模型不能预测吸引力。我们的确切结果，而不是依赖于近似值，表明需要一个新的模型来解释实验结果。
The Poisson-Boltzmann model of colloidal bodies in electrolyte is the basis of a recent numerical calculation predicting attraction between two colloidal spheres confined in a cylinder. The present study formulates an analytical proof that this model cannot predict attraction. Our exact result, not contingent upon approximations, suggests that a new model is needed to explain experimental results.
