摘要: 为了处理泊松玻尔兹曼模型由生物分子中点电荷分布引起的奇异性,文献中提出了多种解的分解式.本文比较研究了泊松玻尔兹曼模型三种常用的解的分解式.即两项分解式、生物分子区域的三项分解式、以及整个区域上的三项分解式.并通过对一个带有解析解的小球模型的数值测试比较了三个分解式各自的优缺点.

Abstract: To deal with the singularity in Poisson-Boltzmann models, which is caused by fixed charge distribution in biomolecules, several decomposition schemes have been proposed in literatures. In this paper, three commonly-used decomposition schemes for Poisson-Boltzmann models are reviewed and compared. That is, a two-term decomposition scheme, a three-term decomposition in biomolecular domain only, and a three-term decomposition in the whole domain. Numerical tests on a Born ball model with analytical solution show the performance of each scheme.
