Chapter 3 Pressure-activated membrane processes M. J. LEWIS, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP 3.1 INTRODUCTION Over the last 30 years, a number of membrane processes have evolved, which make use of a pressure driving force and a semi-permeable membrane in order to effect a separa- tion of components in a solution or colloidal dispersion. The separation is based mainly on molecular size, but to a lesser extent on shape and charge. The three main processes

前面学习了极限、连续函数、实数的连续性,以及导数于微分,特别是重点学习了导 数、微分的概念。我们知道求导是一种运算,它的被运算对象是函数。在以前我们也学过 很多的运算。例如,加、减、乘、除、乘方、开方、指数、对数等等。我们可以将求导运 算与这些已知的很熟悉的运算相类比。(用旧的概念和新的概念相类比,从已有的经验中来 发现新概念、新知识中的规律,这是一种数学方法)我们看看这些旧的运算,我们很快会 发现它们都成对出现,而且每对都是互为逆运算。我们不禁会想到,求导运算是否有逆运 算,它的逆运算是什么?
