Chapter 4 Ultrafiltration M.J. LEWIS, Department of Food Science and Technology, The University of Reading RG6 6AP 4.1 INTRODUCTION Ultrafiltration offers the opportunity to concentrate large molecular weight components without the application of heat or a change of phase. Such components are rejected

1.矩阵的概念:矩阵就是矩形的数表。例如: 代表由pq个数字排成的数表,我们称它为p行q列矩阵。矩阵用大写黑体字母表示。其 下标表示它所包含的行列数,也可省略不写。用小写字母表示矩阵中的各个数字,如a表 示A矩阵中第i行第j列的那一个数字,称为矩阵的元素
