用Poisson-Boltzmann方程,计算了在具有单价离子的电解质溶液中均匀地带同号电荷的两无限大平行平板间的有效相互作用,以及用Derjaguin近似研究了边界对带电胶体球的影响.不考虑微离子相互作用时,两带电平板只有排斥作用,而且边界条件(面电荷密度)的改变对它们之间的有效相互作用影响不大.带电平板与带电胶体球之间的相互作用也有类似规律.
The Poisson-Boltzmann equation is used to calculate the effective interaction between two uniformly parallel plates with uniformly charged charges in an electrolyte solution containing monovalent ions. The Derjaguin approximation is used to study the effect of boundary on charged colloidal spheres. In the case of ionic interaction, the two charged plates have only repulsive effect, and the change of the boundary conditions (surface charge density) has little effect on the effective interaction between them. The interaction between the charged plate and the charged colloidal sphere has a similar rule.
