Filtration operation is in constant pressure differentials, called the constant pressure filter.

过滤操作是在恒定的压差下进行，称为恒压过滤。

The polynomial regression based on the constant-pressure filtration rate equation has been presented to handle the experimental data and compared with the methods in literature through an example.

本文从恒压过滤速率方程出发，利用多项式回归的方法求取过滤常数，并以一实例将之与教材中介绍的方法进行了比较。
