摘要:本文介绍了制浆造纸科学中用于预测主要参数对产品和工艺过程影响的方程范例。一些方程是很久以前由其他学科导出的，沿用于制浆造纸工程技术；另一些方程是制浆造纸研究人员根据基本原理开发的，以解决现有科学未能解决的特别问题。本文简要描述了这些方程的由来、含义和应用，其中“纸浆纤维絮凝的聚集数”以前鲜有提及。

Abstract:This paper described examples of equations employed in pulp and paper science to predict the influences of key variables on pro-ducts and processes. Some equations were derived long ago in other scientific disciplines and adapted for use in pulp and paper technology. Other equations were developed by pulp and paper researchers from basic principles to meet unique needs not addressed in the existing scientific literature. The origin， meaning， and uses of the equations were described briefly.Among them， "Crowding Number for Pulp Fiber Flocculation" was rarely mentioned before.
