颗粒间距（IPS）是用于估计悬浮液粘度的非常重要的参数。在假设每个粒子被一个虚胞包围的基础上，推导出了一个新的计算IPS的方程，虚胞是每个粒子可以占据的自由体积。这个想法是由Kuwabara提出的，并广泛用于计算浓缩悬浮液中的电泳迁移率。我们的新的IPS方程进行了评估，并与预先存在的IPS方程提出的丁格和芬克使用实验数据从三个商业来源的二氧化钛。我们的方程被发现给合理的值，包括情况下，方程的丁格和芬克给异常值。(c)2006年由Elsevier Inc.出版
Interparticle spacing (IPS) is a very important parameter for estimation of the viscosity of a suspension. A new equation for calculating IPS was derived on the assumption that each particle is Surrounded by a Virtual cell, which is the free volume that each particle can occupy. This idea was originated by Kuwabara and widely used for calculating electrophoretic mobility in concentrated suspensions. Our new IPS equation was evaluated and compared with a pre-existing IPS equation proposed by Dinger and Funk using experimental data from three commercial sources of titania. Our equation was found to give reasonable values, including cases where the equation of Dinger and Funk gave anomalous values. (c) 2006 Published by Elsevier Inc.
