Variational implicit solvation models (VISM), because of their relatively low computational cost and satisfactory accuracy, have been widely used in the solvation analysis of biological systems at molecular level. Central in the construction of VISM is an interface separating the solute and the solvent. Compared with sharp-interface models, diffuse-interface VISMs have shown some initial success in improving the efficiency and accuracy of the solvation energy estimation of biomolecules. However, on a theoretical level, several questions concerning the diffuse-interface VISMs remain open

变分隐式溶剂化模型(VISM)，因为其相对较低 计算成本和令人满意的精度，已被广泛应用于 分子水平上的生物体系溶剂化分析。位於中环的 VISM的结构是将溶质和溶剂分开的界面。 与尖锐界面模型相比，扩散界面VISM显示了一些 在提高求解效率和准确性方面取得了初步成功 生物分子的能量估算。然而，在理论层面上，有几个 有关扩散接口VISM的问题仍然悬而未决
